The Additional Harbour Crossing as currently proposed is a pair of tunnels containing six traffic lanes between the motorway at Esmonde Rd rejoining it at Spaghetti Junction [The CMJ] in the city. The publicly available schemes also show additional rail tunnels between Akoranga and Wynyard Quarter, but no connecting network for any trains to actually use. It is clear to see the appeal for NZTA of straightening and simplifying SH1 past the bridge, but the outcomes for the city are much less certain. Below for example is version T1:
Clearly this or the other versions that date from 2010 are not the current versions NZTA are developing now, but until new versions are released these are still worth looking at in some detail as neither the various physical constraints or the overall aims that drive these options have changed. The options can be seen here.
Considering these there are several high altitude observations I think are important to begin with:
- This will be the most expensive urban transport project ever undertaken in NZ; claimed to be $4-$6 billion. Two to three times the cost of the CRL.
- Not least because of the massive cost it is extremely unlikely that both sets of tunnels and systems would be undertaken at the same time. They will be staged; one will precede the other.
- The road scheme is essentially a SH1 bridge bypass, and therefore optimises through traffic, however it does not make any new connection that is not currently available nor in fact any increase in capacity on SH1.
- There is little spare capacity in the CMJ for additional vehicles so the new connection will remain the current three lanes north and a reduction from four to three lanes south.
- Essentially the bridge becomes a massive on/off ramp for city traffic and unless and until the rail tunnels and line are built more buses on bus lanes across the bridge will be the PT part of the project.
Here’s the set of variations currently available for the city end, all versions involve four tunnels under Victoria Park [3 new ones]:
All schemes also involve massive new interchanges on new reclamations at the North Shore end with flyovers and multiple connections between crossings, not unlike the new interchange at Waterview currently being built. Like the outcomes for traffic on North Shore local roads, the impacts of this project will be neither small nor all positive north of the bridge. However for this post I just want to focus on the city-side implications.
Assuming the road crossing is built first, which is consistent with assertions by politicians and officials with phrases like it will be ‘future proofed for rail’, as well as the lack of any real work yet on a rail crossing, it is worth asking exactly where will the new traffic enabled by the extra capacity across the harbour go once in the city?
Because the new crossing plugs directly into the CMJ, three lanes in and three lanes out, and because there are no planned increases in capacity through the CMJ, nor any space for any without further massive tunnelling, in effect the new capacity will be all on the bridge, so coming from the Shore this new traffic will all have to be accommodated by just three off ramps [same in reverse heading north]:
- Cook St; with new direct connections through Victoria Park
- Fanshawe St, especially for buses on new bus lanes
- Shelly Beach Rd, and then on to Jervois and Ponsonby Rds.
None of these exits can accommodate any increasing in traffic well, or without considerable disbenefit, especially if that increase in traffic is large.
- Cook St is pointed directly at the heart of the city, so this contradicts policy of reducing vehicle volumes in the city centre and is likely to infarct daily at the peaks as Cook St is close and perpendicular to Hobson and Nelson Sts which serve the Southern and Northwestern motorway flows. Gridlock is likely at the controlled intersections unable to handle large and peaky traffic volumes to and from these motorways. Additionally land use in this area is changing and intensifying making it even less suitable for the high speed motorway offramp it already hosts.
- Fanshawe will have reduced capacity for general traffic as a multilane Busway will be required to take the increased bus volumes from the bridge, and anyway is already at capacity at the peaks.
- Shelly Beach Rd is a narrow residential street not suited to the high volumes and high speeds it already suffers from the bridge now. Furthermore there is no benefit and little capacity for the streets beyond Shelly Beach Rd, particularly Jervois and Ponsonby Rds for a large increase in vehicle volumes.
Nonetheless, here are the forecasts they have come up with, Shelly Beach Rd with a 63% increase, is basically filled with bridge traffic by 2026 and the new crossing:
20,300 additional cars modelled for Fanshawe + Cook St with the AWHC option (assume that is all day on a weekday?). Even at the best sorts of turnover that would require around 10,000+ new carpark places. The downtown carpark has 1890 spaces. So where exactly do we put six new downtown carpark buildings? And what six streets get sacrificed to feed them?
20,300 cars carry perhaps 25,000 people. The CRL at capacity will carry that entire amount in 40 minutes. As could a North Shore rail line of similar specification. If the net outcome of this project is to take 20,000 commuters to midtown, why not do it with rapid transit at a third the cost with none of the traffic congestion?
“The significant increase in traffic movements conflict with many of the aspirations outlined in current Council policies, strategies, frameworks and master plans.”
–P 65 Additional Waitemata Harbour Crossing Network Plan, NZTA, 2010.
Obviously these higher traffic volumes are not good for every pedestrian, resident, and general city user in these areas but there is one other group that this situation in particular is going to make miserable, and that’s the motorist. There is a word for all this additional driving everywhere on city streets: congestion. Yup this increase in capacity across the harbour may speed that part of the journey but it’s going to make arriving anywhere in the city in your car much more hellish than it is now. And don’t even think about finding or affording somewhere to park.
What NZTA’s consultants say about this:
The increased traffic flows through St Marys Bay on both Shelley Beach rd and Curran St look to lead to particularly poor and unfixable outcomes:
It seems optimistic to say that because there are cafes, and strongly increasing pedestrian volumes, on Ponsonby Rd, that drivers won’t try to drive there, especially if other bridge exits are controlled or too busy. After all the first rule of urban traffic is that it will expand to wherever it is allowed to go. So, in the end, taking measures to dis-incentivise drivers to use these exits, is the consultant’s advice:
It does seem kind of odd to spend $4-6 billion to increase capacity across the harbour only to then introduce other measures to try to stop people using it.
And it won’t be just parking, there’s also likely to be tolls, it appears the model says they can pretty much eliminate the traffic problem with an $8 toll!:
If only there was a way to enable more trips without inducing more and more cars to also be driven into the crowded city streets. After all the City Centre has been growing strongly without adding more cars most of this century:
In fact it looks like we are already at or even above the limit of desirable vehicle numbers in the city, and future developments like replacing car access to Queen St with Light Rail are likely to make even current numbers face pressure.
Additionally there is an issue with bus volumes as well as car numbers on the city streets, even though the New Bus Network, the CRL, and Light Rail, if it happens, will reduce bus numbers from other parts of the city, there is certainly a limit to the numbers of buses from the Shore that can be comfortably accommodated too. Below is the predicted year of maximum bus capacity at major entry points to the city. The role of the CRL in reducing bus number pressure from the Isthmus is obvious, so why not do the same thing for buses from the Shore?
So perhaps the answer is to reverse the assumed staging and build the rail Rapid Transit tunnels first, leaving space for the road crossing to come later. This certainly looks physically possible in the maps above. This would enable all of those possible trips across the Harbour that NZTA identifies to still be served but without any of the traffic disbenefits that so clearly dog the road only crossing. In terms of people capacity two rail tracks can carry twice the volume of six traffic lanes. Furthermore it can be built without disturbing the current crossing and its connections. And rail crossings have proven in the past to be good alternative routes in an emergency.
This would add the real resilience of a whole other high capacity mode across the Harbour instead of simply more of the same. It would make our Harbour infrastructure more closely resemble Sydney’s where most of the heavy lifting in terms of people numbers is done by Rapid Transit, as shown below. We already have ferries, buses, and cars bringing people across, isn’t it time we added the particular efficiency of electric rail?
It seems particularly clear that whatever we add next really can’t involve trying to shove ever more vehicles [cars and buses] onto our crowded city streets; that will simple hold everyone up.
All the information above was gleaned from the work done some six years ago for NZTA, from here, and Auckland has moved on a great deal from where it was then. Among other things that have been proven recently is that when we are offered a high quality rail system we will use it. We are also discovering the value of our City Centre as a place to live, and work, and just be in, and how this is only possible to continue this improvement with fewer cars on every street. We certainly believe that there are more options for a far greater Auckland than the simple binary ones studied above: the road crossing ‘future proofed’ for rail, or the ‘Do Minimum’ which is nothing.
So we have asked, as part of the Auckland Transport Alignment Process, for a Rapid Transit crossing as the next additional crossing to be modelled too. So we can compare the status quo with the road crossing, and with a Rapid Transit crossing separately. Additionally we know that AT are now working on how various rail systems could work so in time there will be properly developed rail options to compare with the road one.
There is time as well as the need to get this right, the Western Ring Route will begin to become more complete next year with the opening of the Waterview tunnels, and that whole multi billion dollar system is of course an alternative harbour crossing system and will alter both the performance of both the Bridge and the CMJ. Similarly decisions about AT’s proposed LRT system too has a bearing on options, as will the opening of the CRL next decade. Not least because the addition of these high quality systems will make movement through the city without a car much more common, as is the case in many overseas cities of Auckland’s size and quality.
The road crossing looks very much like an extremely expensive ‘nice to have’, that duplicates and tidies up the State Highway route, something to add when the missing alternatives have been built and there is spare budget to spend on duplication. Because on balance the road first additional crossing proposal really achieves little more than this:
There are many reasons to be concerned about the plan to add more road lanes across Auckland’s Waitemata Harbour: from the extreme cost of building such big tunnels and interchanges [$5-$6 billion and four times as much as just building rail tunnels], to the undesirable flooding of city streets and North Shore local roads with even more cars, to the increase in air pollution and carbon emission this will create, the loss of valuable city land to expanded on and off ramps and parking structures, to the impact on the harbour of exhaust stacks and a supersized motorway on the Shore, to the pressure this will put on the rest of the motorway system particularly through the narrow throat of Spaghetti Junction. It is both the most expensive and least efficient way to add capacity across this route, and if resilience is the aim then the double-down on reliance the motorway system rather works against this. This one project will simply crowd out any other changes we could make of scale in Auckland or the country for years; yet it changes almost nothing; it simply enables more vehicles to travel across a short point in the middle of the city, yet this is by no means an obviously good thing: The list of unwanted outcomes from the current proposal is so extensive that the benefits had better be so extraordinary and so absolutely certain in order to balance them all.
But perhaps there is no greater reason to not do it than that it simply won’t improve things for drivers.
Really? How can this be? As well the obvious problem with this project that it will add super capacity for a short stretch of the motorway network and therefore just shifts any bottleneck to the next constriction, particularly the extremely difficult to expand CMJ or Spaghetti Junction, there’s also a bigger structural problem with building more roads to fight traffic congestion. It can’t work. We all have experienced being stuck in traffic on a motorway and sat there wishing if only the authorities had just built an extra lane all would be sweet, well it would, wouldn’t it? However the evidence from all round the world shows that while that may help for a little while it never lasts, especially in a thriving city and especially if these extension starve the alternatives of funding, condemning ever more people to vehicle trips on our roads. Soon we’re stuck again wishing for another few billions worth of extra lanes all over again.
Here’s how it works; each new lane or route simply incentivises new vehicle journeys that weren’t made before; a well known phenomenon called induced demand. Road building is also traffic building, the more we invest in roads the more traffic and driving we get, and not just on the new road; everywhere. Traffic congestion is, of course, simply too much traffic, too much driving. Take for example the I-10 in Houston, the Katy Freeway. In that famously auto-dependent city they freely spent Federal money and local taxes disproportionately on just one way to try to beat traffic congestion, the supply side: ever more tarmac [Houstonians can boast the greatest spend per capita on freeways in the US]. The I-10 which began at six to eight lanes has just had its latest ‘upgrade’ to no fewer than 26 lanes! That ought to be more than enough in a flat city with multiple routes and only half the population Los Angeles. So what happened? According to recent analysis it has made driving this route significantly worse.
Traveling out I-10 is now 33% worse – almost 18 more minutes of your time – than it was before we spent $2.8 billion to subsidize land speculation and encourage more driving.
But hang on, those trips must need to be made, right, or people wouldn’t make them. Well in the absence of direct pricing it is hard to know exactly how valuable these new trips are. So first they really ought to price routes like the I-10 properly to reduce unnecessary journeys clogging up the valuable ones, like the truckies and trades [it is partially tolled now]. But the real problem in cities like Houston is the absence of any useful alternatives to driving [an earlier extension of I-10 took out an existing rail line!]. Providing those alternatives is how congestion is best dealt with. Not completely solved of course, that can only happen by collapse of the city economy like in Detroit, and no-one wants that solution. But traffic congestion can be made both manageable and, for many, no longer an issue, by providing them with attractive alternative options. And in turn this frees up the roads sufficiently for those who have to or prefer to drive. Especially when this is done in conjunction with direct price signals- road pricing; tolls or network or cordon charges.
Houston may be forever too far gone down this hopeless road but that doesn’t mean we have to follow it. Here is a description of the same problem in Sydney, with the solution:
Most people will take whichever transport option is fastest. They don’t care about the mode. If public transport is quicker they’ll catch a train or a bus, freeing up road space. If driving is quicker, they’ll jump in their car, adding to road congestion. In this way, public transport speeds determine road speeds. The upshot is that increasing public transport speeds is one of the best options available to governments and communities wanting to reduce road traffic congestion.
This is called the Nash Equilibrium [I would rather say better than faster; there are a number of variables including speed that inform our choices];
This relationship is one of the key mechanisms that make city systems tick. It is basic microeconomics, people shifting between two different options until there is no advantage in shifting and equilibrium is found. We can see this relationship in data sets that make comparisons between international cities. Cities with faster public transport speeds generally have faster road speeds.
Which brings us to the Waitemata Harbour. It currently has 13 general traffic lanes across two bridges, one walking and cycling lane on the upper harbour bridge, and some ferry services generally not competing with these crossings. The Harbour Bridge carries increasing numbers of buses from the hugely successful Northern Busway, the very success of which exactly proves the theory of the equilibrium described by Dr Ziebots above. In the morning peak the buses carry around 40% of the people without even a single dedicated lane on the bridge itself. And it is all the people using the busway that allow the traffic lanes to move at all. In fact NZTA argue that one of the main reasons for building a new crossing is the numbers and the size of the buses now using the current one.
The Upper Harbour Bridge is about become significantly busier because of the multiple billions being spent on the Waterview connection between SH20 and SH16, the widening of SH16, and the bigger interchange between SH81 and SH1 on the Shore. These huge motorway expansions will generate more traffic of course, but also will provide an alternative to driving across the lower Harbour Bridge.
What is missing anywhere between the North Shore and the city is a Rapid Transit alternative to these road lanes. Like Sydney always has had.
It is its [Sydney Harbour Bridge] multi-modality that makes it truly impressive, some 73% of the people entering Sydney on the Bridge from the Shore at this time are doing so on just one of the train lines and one bus lane; a fraction of the width of the whole structure. So not only does it shame our Harbour bridge aesthetically it completely kills it for efficiency too.
Auckland’s bridge was always only ever designed for road traffic, and should be left that way, the clear way forward is to add the missing Rapid Transit route as the next major additional crossing [after adding the SkyPath to the existing bridge].
In 1992 it [Sydney Harbour Bridge] was supplemented by a pair of two lane road tunnels that up the cross harbour tally for this mode to match the number coming over by train [bridge plus tunnels = 12 traffic lanes], but that wasn’t done until the population of the city had hit 3.7 million. The high capacity systems on the bridge saved the people of Sydney and Australia from spending huge sums on additional crossings and delayed the date they were deemed necessary by many decades. But anyway, because the additional crossing is just road lanes it only adds around 10% extra capacity to the bridge. To think that the government here and NZTA are seriously proposing to spend multiple billions in building a third Harbour Crossing in Auckland with the population only at 1.5m, but not only that but they are planning to build more capacity for the least efficient mode; more traffic lanes.
The good people at NZTA of course know this, but we just seem stuck in a bad habit of road building in a similar way as Houston is, because the money for motorway building comes from central government some people believe this makes it free, in a similar way that the highways in the US are largely funded by the Federal government, unlike public transport, which is more locally funded [Known as ‘path dependency’ and is well covered in the academic literature: Imran, Pearce 2014]. This means the pressure to evaluate the effectiveness of motorways over the alternatives is much weaker. Here is a slide from an NZTA presentation proudly proclaiming how much more traffic this massive project will generate:
Of course this growth can be met by a parallel Rapid Transit system instead. The success of the Busway here and the enormous uptake of the recently improved Rail Network show that Aucklanders are the same as city dwellers everywhere and will use good Transit systems when they get the chance. And two much smaller and therefore cheaper train tunnels have much greater capacity than the proposed six traffic tunnels. Twice as much in fact: the equivalent of twelve lanes and without adding a single car to city streets. Furthermore converting the Busway to a rail system, which is entirely possible, and depending on the system may even be quick and easy, means that buses can be completely removed from bridge freeing up more capacity there for general traffic; cars and trucks:
- Removing buses from the existing bridge would free up some capacity. 200 buses per peak hour ~= 1,000 cars ~= 60% capacity of a traffic lane. So a dedicated PT crossing provides car users with an extra lane (once you account for reverse direction). Not huge, but not negligible either.
- Mode shift: by providing a fast and more direct alternative route you will get mode shift, providing more space to the cars that remain. So you have more vehicle capacity and less demand = a real congestion benefit.
So compared to a new road tunnel where both crossings would need to be tolled, and simply generate more competing traffic for drivers through the whole city, the dedicated PT option would seem to be better even for motorists. The better, faster, and more attractive the Rapid Transit route the freer the driving route will remain; with more people choosing the car-free option: The higher the Transit utility; the higher the driving utility.
Of course while a rail crossing will be considerably cheaper to build than a road crossing it still needs a network either side of the harbour to make it useful. Are there good options for this? In fact there are a number of very good options, all with varying advantages and disadvantages that need serious investigation. And it is important to remember by the time this project is being built the public transit networks in Auckland will be considerably more mature. The City Rail Link will have transformed the newly electrified rail network to a central role in the city, it will quickly have doubled from 2015’s 15 million annual trips to 30 million and more. The New Bus Network will be functioning and with the new integrated zonal fare system meaning people will be used to transferring across routes and modes to speed through the city. The increase in bus numbers and population will make driving in the city less functional. There will certainly many tens of thousands more people in the city without their car, many with business or other reasons to travel across to the Shore. And importantly there will almost certainly be a new Light Rail system running from the central isthmus down Queen St and terminating downtown.
The quickest and cheapest to build will probably be to take the city Light Rail system through Wynyard Quarter and across the harbour, as outlined by Matt here. The busway can be most easily converted for this technology, as it is already designed for it. Furthermore being the only rail system that can run on streets it can also most easily include branches to Takapuna and even Milford to the east, and from Onewa up to Glenfield. This also has the advantage of balancing the existing city-side routes, unlocking a downtown terminus, not unlike the CRL does for the rail network.
What a North Shore light metro network map might look like.
Higher capacity and with the great advantage of cheaper to run driverless systems are is Light Metro like the massively successful SkyTrain in Vancouver. As described for Auckland here. However like extending our current rail system to the harbour it would require a more expensive city-side tunnel to Aotea Station for connection to city network. We know work has been done to prepare Aotea station for this possibility. Matt has also explored other variations here.
Perhaps the best answer for both the near term and the long term is to build tunnels that can take our new Light Rail vehicles for the years ahead but are also capable of being converted to the higher capacity Light Metro when the demand builds so much to justify the further investment of the city tunnel between Wynyard and Aotea Station. Bearing in mind the LR vehicles AT are planning for are high capacity [450pax ] and they can run in the cross harbour tunnels and the busway at very high frequencies. And that Light Metro systems can use track geometries much closer to LR than can conventional rail systems.
So in summary, the bane of the motorist and the commercial driver, traffic congestion, is best dealt with on the demand-side as well as the supply-side. We have spent 60 years just supplying more tarmac, and now it is time to get on with addressing the demand side: Building quality alternatives and providing clear incentives to fine-tune peoples choices.
And, just like road building, investing in quality Rapid Transit will grow the demand for more of it. It will also shift land use, incentivising agglomeration economies and greater intensification around transport nodes, as well as individual habits to suit this option more. What we feed, with infrastructure investment, grows. And vitally, inducing this sort of movement instead of driving is entirely consistent with other the demands of this century; especially our country’s new commitments to reduce our carbon emissions, and the use of our own abundant and renewably generated energy.
This project is both so expensive and potentially so valuable or so damaging that it needs a fully informed public debate about the possibilities. Gone are the days that NZTA can just keep building what its used to without real analysis of all alternatives, or that a politically expedient option sails by without serious evaluation. Because it can be transformed into a truly great asset for the city and the nation on this important route from the eye-wateringly expensive and clearly dubious idea from last century that it is now.
What’s clearly missing from this picture, especially once Light Rail fills ‘The Void’, and some form of rail goes to the airport?:
Body without a head: Official post CRL rail running pattern
The more I look at the events and data of 2015 the clearer it becomes that this has been a profoundly significant year for Auckland. It is my contention that this year the city reached a critical turning point in its multi-year evolution back to true city pattern. I have discussed this change many times before on this forum, most notably here, as it is, I believe, an observable process that has been building for years. Generally it has been gradual enough, like the growth of a familiar tree, as to easily pass unobserved, but now I think it has passed a into a new phase of higher visibility. The group who see it most clearly are people returning from a few years overseas. Many ex-pats express surprise and wonderment at the myriad of changes in quantity and quality they find here on returning.
Changing City: New apartments with views over the city and harbour, a Victorian school and park, 20thC motorways, and the new LigthPath.
Below is a summary of evidence for 2015 being the year Auckland returned as a city, in fact the year it crossed the Rubicon onto an unstoppable properly re-urbanising path. Later I will add another post on how 2016 and beyond is certain to see the city double-down on these trends, and why this is very good news. This transformation is observable in all five keys areas:
DEMOGRAPHICS. New Zealanders returning in big numbers are one of the key metrics of 2015. Along with new migrants and natural growth, the other change driving Auckland’s demographic strength is fewer people leaving, all of which, of course, are a vote of confidence in the city as a place to want to live and to likely fulfil people’s hopes for a better future. Population growth for the year was at 2.9%, the strongest rate since 2003, the strongest in the nation, and biggest raw number on record. See here for Matt’s [Population Growth in 2015] and Peter’s [Why is Auckland Growing?] posts on these issues.
And importantly for my thesis many more people are moving into the centre, particularly into new apartments. This is a evidence that the The Great Inversion is happening in Auckland as it is all over the developed world; the return of vitality to centre cities all over. Auckland’s urban form is reverting to a centred pattern; with proximity to a dense centre as a key determinant of value.
TRANSPORT. The huge and sustained boom in rail ridership way in advance of population growth is the headline transport news of 2015, and is the result of the upgrade in quality, frequency, and reliability of the service brought by the new electric trains. Sustained growth of over 20% is very strong; this year every four months an additional million trips have been added to the running annual total; 13 million in March, 14 million in July, 15 million in November. I am not overstating it to say that these numbers change a great deal: They change the argument for further investment in rail systems in Auckland, and significantly they change growth and development patterns across the city:
Elsewhere on our Public Transport systems the news is great too; The New Bus Network is just beginning, and is already showing huge growth in the few areas it is in effect. This year we have also seen new ferry services, including a new private Waiheke service that means there is much more like a real turn-up-and-go service there [started late 2014]. Ferry modeshare is holding its own at 7% which is a strong showing given the explosion in rail and bus numbers.
Importantly AT is now routinely rolling out long overdue bus lanes across the city. And now that they are doing this confidently and more consistently, surprise and anguish about this more efficient re-purposing of roadspace by car drivers has fallen away to nothing- there surely is a lesson there.
So total PT ridership cleared 80 million annual trips this year, for an overall growth of 8.1%, a rate running at nearly 3x population growth, evidence of a strong shift to public transport at the margin. Growth that is certain to continue despite capacity issues becoming pressing at peak times on both buses and trains.
HOP card use also became strongly embedded this year [except on the ferries] which is another sign of a maturing system.
More population and a growing economy of course means more vehicles and more driving on our roads, [see: What’s Happening to VKT?] but because of the powerful trend to Transit outlined above the per capita number is flat to falling. This is a historic shift from last century when the two tended to move strongly in lockstep.
Another discontinuity from last century is that GDP and employment growth have also separated from driving VKT, as shown in the following chart from Matt’s post linked to above. Another sign that the economy too is shifting on the back of public transport, and not driving as much as it was last century:
So whereas investment in the rail network has been answered by an extraordinary boom in uptake the multi-year many billion dollar sustained investment in driving amenity has not led to massive uptake. It is hard to not conclude from this that 1. We are far from discovering the latent demand ceiling for quality Transit; only the degree of investment will limit it. And 2. Driving demand in Auckland is saturated; this mode is mature, well served and not the area to invest in for new efficiencies or growth.
2015 also saw the launch of the Urban Cycleways programme; a multiyear government led investment in infrastructure for walking and cycling. This, like the Transit boom is another shape changing departure from the past. Although the active modes are not well counted [what a culture counts shows what it values] it is clear that the shift back to the centre is also accompanied by a growth in active mode transport. This is one of the great powers of Proximity; the best trip is the one that isn’t need because the potential traveller is already there, or near enough to use their own steam:
DEVELOPMENT. All over the city investment is going into building projects of various kinds, the retirement sector is particularly strong, as is terrace house and apartment buildings, all three at levels not seen for a decade and together support the argument that Auckland is not just growing but also changing shape into a more more city-like pattern, as John Polkinghorn has kept us up to speed on all year on the Development Tracker:
Significantly there is also renewed investment into commercial projects especially in the City Centre, led by Precinct Property’s 600 million plus Downtown rebuild and tower, and Sky City’s massive Convention Centre and Hotel project between Hobson and Nelson. Additionally Wynyard Quarter is also moving to a new level soon with a mix of Hotel, Residential, and Commercial buildings. Somewhere in the region of 10 billion dollars of projects are underway or close to be in the City Centre. And as Peter clearly illustrated recently this is in no small part due to improved regulatory conditions [The High Cost of Free Parking].
ECONOMY. Cities exist simply because of the advantages for humans to be in close proximity to each other for transactions of all kinds; financial, cultural, social, sexual. And Auckland is beginning to show real possibility of opening up an agglomeration advantage over the rest of the country now that it is really intensifying. The latest data on Auckland’s performance shows a fairly consistent improvement over the last five years
POLITICS. Two major political programmes begun this year will have profound impacts on Auckland for decades to come. The first is the Auckland Transport Alignment Process. Something we haven’t discussed on the blog because we are involved in it and are awaiting the first public release of information which will be soon. Then we will certainly be discussing the details of this ongoing work. But the importance of this process is already clear; it is a reflection of a new found acceptance but the government that Auckland’s economic performance matters hugely to the nation and that transport infrastructure investment is, in turn, critical to that performance. We are of course striving to make the case for a change in the balance of that investment in Auckland away from a near total commitment to urban highways now that motorway network approaches completion [post Waterview and Western Ring Route] and that the evidence of success from recent Transit improvements, particularly to the Rapid Transit Network, is so compelling. There are hurdles here in the momentum and habits of our institutions and politics but also huge opportunities to really accelerate our cities’ performance across a range of metrics through changing how they are treated.
The other political shift is another we are yet to cover in depth but soon will, and that’s the agreement in Paris on Climate Change. This does indeed change a great deal. The city and the nation will have to ask the question of all decisions around urban form and transport how they fit with the new commitment to reduce our carbon intensity. This will clearly lead to a further push for higher density and greater emphasis on Public and Active Transport, as these are current technology and long term fixes to this global challenge. Unleashing further the urban power of proximity and agglomeration economies. So much of the conversation around New Zealand’s carbon intensity is around the agricultural issue and this tends to ignore the opportunities our cities offer, particularly Auckland, and particularly the Auckland transport systems, to this problem.
Cities are emerging as the key organising level that are most able to react to this problem as discussed here in The Urban Planner’s Guide to a Pst-COP21 World:
In many ways, Melbourne’s experience represents a coming-of-age of the urban sustainability movement. The private sector is listening to cities and responding. Now it’s up to cities and national governments to continue the conversations that began at COP21 and continue the evolution.
“The commentary for a long time has been ‘nations talk and cities act.’ We’ve been part of that dialogue too. That’s changing now,” said Seth Schultz [director of research at C40 Cities]. “National governments are coming to organizations like ours and saying ‘help us. We get it.’ I want to change the trajectory of the conversation. Cities are a vehicle and everyone should be getting in that vehicle and joining in for the ride.”
So in summary 2015 has seen:
- Completion of Electrification of the Rail Network and the New Trains
- The start of the New Network
- New Interchange Stations
- New Buslanes
- Improvements to Ferry services
- Start of the Urban Cycleways Programme
- CRL start
- Paris COP 21
I will follow this post with another looking ahead to what is going to be a huge 2016/17. Here’s a short list to start with:
- Fare Integration
- Further Interchange Stations
- Western Line frequency upgrade
- New Network rollouts

For all the frustrations and compromises that we’ve highlighted over the year I think it’s very clear that there are many very hard working and dedicated people in AC, AT, NZTA, and MoT and their private sector partners and it is their collective efforts in a very fast moving and changing field go a long to making Auckland the dynamic and exciting city it is fast becoming. I am keen to acknowledge their efforts. Onward.
I also want to personally thank my colleagues here at the blog, as it has been another big year for us, Matt, Peter, Stu, Kent and John, from whom I continue to learn so much, it doesn’t look like we are going to be able to give this up anytime soon…
Also I would like to shout out to colleagues over at Bike Auckland, our sister site, they’ve had a fantastic year, so cheers to Barb, Jolisa, Max, Paul, Kirsten, Ben, Bruce and the rest.
And of course to y’all, the reader, you are what really makes this thing work, so if what we do here makes any kind of difference, ultimately that’s because of you.
Kia ora tatou…
The Productivity Commission has put out a paper calling for submissions on Urban Planning, here. It’s a very wide ranging, going right back to first principles where they have discovered that:
Yet even among planners, there appears to be no agreed definition of “planning” or “urban planning”, and writers have struggled with whether a definition can be provided.
Despite this lack of theoretical certainty I think we all know urban planning when we see it, or perhaps more accurately its outcomes. Pleasingly the paper begins with a short history of Petone which is used to illustrate the accretive and accidental nature of city forming:
The changing nature of urban areas
Urban areas are dynamic, complex places. Land uses and neighbourhoods can change dramatically in response to economic, technological and demographic forces.
One example of this evolution comes from Easterly, Freschi and Pennings (2015), who explored how a single stretch of a New York City street changed over four centuries of development. Easterly, Freschi and Pennings concluded that it is “difficult for prescriptive planners to anticipate changes in comparative advantage, and it is easy for regulations to stifle creative destruction and to create misallocation.” (p. 1)
The town of Petone in Lower Hutt illustrates the diversity of influences that shape urban areas. [Below] provides an outline of its history, although inevitably many important details and events are overlooked. The transition of Petone – from a Māori village, to the intended site of a major colonial settlement, to a working-class industrial area, a run-down town, at various times a retail destination, and a desirable residential neighbourhood – show how unpredictable the evolution of our urban areas can be.
Given this surely accurate observation, shouldn’t any attempts at controlling the form of our cities in fact shy away from control but instead aim for incentivisation? Won’t nudging the direction of individual impulses be likely to be more effective that prescriptive programmes? And much less likely to result in unwanted unintended consequences, like out of control dwelling inflation. After all it appears that even the most egregious of city ordinances are well meant, no matter how much damage they do either indirectly or to other aims. And city building is full of contradictory impulses; for example nothing allows more retention [if not preservation] of older building than economic stagnation, yet surely it is fair to say there are few if any councils that would consciously pursue policies of economic ruin in order to bolster their worthy desire to preserve their city’s built fabric?
Another example is the whole history of auto-priority of the last 60 years across the developed world; so often expensive road and parking infrastructure was built with the very aim of reviving or maintaining the economic life of places, yes these investments simply reinforced their decline and unsuitability of these places for the brave new world of driving focussed city. For example Auckland’s City Centre only really began to recover from the flight of the motorway/sprawl era once Minimum Parking Regs were inverted- replaced with Maximums instead. Thereby nudging development and use of the city towards walkable proximate-focussed more intense land use. In fact MPRs must rank very high up the list of the most destructive yet well meant influences on city development, see this disastrous example from the sadly much governance-abused city of Christchurch; so prioritising ease of parking that the actual destination become untenable and disappears. Mandated parking oversupply is a form of urban self-harm so ubiquitous in mediocre conurbations that it’s become invisible: it’s the teenage cutting of city-management.
The question next becomes what scale of nudge is required to incentivise more productive city building and city using; nudge or shove? Denmark for example, has a 180% tax on new cars and one the highest bicycle usage rates in the world. These two things are surely not unrelated [see here for context, however]. Japan, Singapore, and Hong Kong all have the most widespread and financially successful urban, and in Japan’s case, inter city, Transit networks and all also have significant barriers to car ownership and use, as well as planning rules that enable more efficient land use. See here.
Here is the ProdComm’s quick history of the urban development of Petone:
The evolution of Petone
Prior to European settlement there was a large Te Āti Awa Pa at Pito-one. The New Zealand Company’s surveyor, Captain William Mein Smith chose the Heretaunga (Hutt) river valley for the site of their planned settlement “Britannia”, and the Company ships began arriving in January 1840. Relations between Māori and the settlers were positive in large part due to the hospitality and mana of local chief Te Puni. The grid street plan drawn up in England was soon abandoned. In March the river flooded the settlement, and a fire and earthquake followed in May. Britannia was largely abandoned by the end of 1840, with the settlers having moved to Pipitea/Thorndon, which Colonel Wakefield had long favoured for the settlement.
In 1847 there were probably no more than 20 settler households left, and it remained almost wholly deserted until 1875. The land was poor quality for grazing, and the Hutt River flooded at least annually. Pito-one Pa, with a population of 136, remained the largest and best-fortified pa in the Wellington area. In 1855 a major earthquake lifted the area, draining a portion of the lower valley.
In 1874 the Wellington-Wairarapa train line opened. A large railway workshop was built in Petone. That same year a butcher, James Gear, began to purchase and lease land around the Petone foreshore for a slaughterhouse. It was attractive for the cheap flat land, proximity to the harbour and railway line, and the small size of the local population to be offended by the waste and smell of the facility. In 1883 the company built a 380m long wharf, demolished in 1901. A large wool mill was established in 1886.
Petone grew rapidly, and was gazetted as a town in 1881. A series of factories and breweries were built. Schools, churches, newspapers, sports and social clubs were established in the 1880s, many of which survive today.
A local farmer, Edwin Jackson, sold portions of his land piecemeal with unsurveyed rights- of-way. The result was that by 1885 there was local concern that Jackson Street was an embarrassing series of dog-legs, of varying width along its length. Jackson Street was extended when the land was bought by the borough solicitor on behalf of the Crown in 1888. Blood and offal went straight into the harbour, attracting sharks, so Jackson built a swimming bath near the waterfront. Plans for a gasworks were abandoned in 1897, and the land that had been earmarked for this use was purchased by the council as a recreation ground. But the council declined to buy Jackson’s baths, and a ratepayers poll in 1901 also decided against a purchase, so they were closed.
By the early 1900s Jackson Street was the hub of Hutt Valley commercial activity, with notable stores such as McKenzies, McDuffs and Liebezeits. The Grand Theatre opened in 1916. But Jackson Street’s haphazard alignment was still a problem and between 1927 and 1938 the council widened and straightened Jackson Street, with buildings shifted back on rails or demolished.
New Zealand’s earliest state houses were built in Patrick Street from 1906, although they were sold in the 1930s. Council chambers were built in 1903 and a town clock in 1913. A new wharf was constructed in 1907. Industrialisation continued: Lever Brothers factory opened in 1919, Sunlight Factory in 1924, and a number of car plants in the 1920s and 1930s. Three out of every four cars in New Zealand were said to come from Petone up until the 1950s. The town produced many successful sportspeople and the Petone Rugby Club numerous All Blacks.
Petone, by local standards, was densely populated and heavily industrialised, ugly, grimy, lively and close-knit, more like an English industrial town than a New Zealand one. (Butterworth, 1988, p. 13)
But from the 1950s the area began to decline, as some industries closed and residents moved to the new suburbs of the Hutt Valley. A number of state housing flats were built from the 1950s to the 1970s on the eastern part of Jackson Street. The Borough Council designated an area north of Jackson Street as an industrial zone, and
[t]he result of this was that no one was allowed to improve their properties, which meant many fell into disrepair and were sold off to developers. It was impossible for young Petone people to get a loan to buy property in their hometown so many left for Wainuiomata or Upper Hutt. The town become a place of rented properties owned by absentee landlords. By the mid seventies and eighties Jackson Street was pretty much derelict. (Johnston, 2015, pp. 93-95)
The Council proposed building a ring road around central Jackson Street, to create a mall in the centre of town at a cost of $10 million and the demolition of 80 houses. But significant local opposition stopped the project, and many councillors were voted out.
Petone wharf took its last cargo in 1976. The Gear meatworks closed in 1981. Long- established stores closed and the council chambers were demolished in 1986. Deregulation of the New Zealand economy resulted in many of the remaining factories closing. Developers who were demolishing and rebuilding in Wellington regarded Jackson Street as a place of little commercial potential, so its old buildings were left untended. In turn, “this stagnation ironically preserved the historic CBD as a desirable social and economic centre” (Johnston, 2015, p. 177). Petone recovered in the 1990s as industrial land uses gave way to big box retailing in the west of Jackson Street. Petone again became a retail destination, and this benefited the smaller shops along Jackson Street. A burgeoning bar, café, gallery, and retail sector followed. In 1996 the Historic Places Trust recognised Jackson Street as an Historic Area, but this had no regulatory force. There were a number of battles between local heritage groups, developers and the council over the next decade.
The “character homes” of Petone and its proximity and transport links to Wellington made Petone a desirable residential neighbourhood. A number of apartments were built or converted, consistent with council design guidelines. In 2014 it was announced that many of the state housing flats on the eastern part of Jackson Street were to be demolished, but the Patrick Street cottages survive and are protected. The Grand Theatre, which closed in 1964, was used as an electrical shop, furniture business, and in the 1990s was converted to an apartment complex with boutique shops below. Today, the site of the Gear meatworks is a supermarket, and Petone wharf is a popular fishing location, with fewer sharks than in the past.

Apartments, tower cranes, and the coming new cycling/walking amenity right in the heart of the city’s motorway singularity.
If you live in the North West and were looking forward to the end of what has now been over five years of constant road works along the Northwestern Motorway – which started with Lincoln Rd back in October 2010 – then don’t get your hopes up for the disruption ending any time soon. The NZTA are now starting to once again talking about the section they’ve so far missed in their grand widening schemes – the bit between Lincoln Rd and Westgate. What’s more despite being silent on the project for so long they’re now talking about starting the $100+ million widening project in little over six months with work expected to take till 2019 to complete.
The NZTA say the project involves
- Widening the motorway to create 3 lanes in both directions for motorists
- Creating bus shoulder lanes next to the motorway in both directions
- Extending the Northwestern Cycleway to create a 3-metre wide shared walking and cycling path from Lincoln Road to Westgate
- Improving the Royal Road interchange and ramps. Replacing, raising and widening Royal Road Bridge, creating an on-road cycle lane, shared walking and cycling path, and new footpath
- Replacing and raising Huruhuru Road Bridge
- Extending the Lincoln Road on-ramp heading westbound and replacing one side of the bridge over Huruhuru Creek
- New landscaping, urban design and lighting features
- New wetlands to treat stormwater run-off
- Improved safety barriers and new noise walls.
I’m not necessarily opposed to the project as there are some useful aspects to it but it does seem to have the typical motorway building approach to it – that being to widen everything around this section thereby increasing the justification for to spend a heap of money ‘fixing’ on the newly created bottleneck.
Probably the most useful aspect of the project for me personally and one I’m very keen to see built is the cycleway. Normally cycleways alongside motorways aren’t great however in this situation the motorway has a shallower grade than the surrounding streets do so will be a welcome addition. That brings me to my first issue/concern. The map above shows the cycleway veering off with the motorway ramps to Makora Rd which is steep and quite narrow. As Royal Rd is on a ridgeline it means that diversion adds additional height for those on bikes (or walking) to deal with. I’d prefer to see the cycleway pass under the offramp and then stick to the level of the motorway – obviously with a connection to Royal Rd. The diversion also adds at least two sets of traffic lights that need to be negotiated.
An issue perhaps even more important is the situation for buses. The NZTA are only building bus shoulder lanes in the project. While bus shoulder lanes are better than nothing it ignores that Auckland Transport want a full busway built on this section – although AT acknowledged in the West Auckland New Network consultation that bus shoulder lanes would go in first.
What it all means is that AT will still have to build a busway separately at some point in the future at a much larger cost rather than the NZTA taking the One Network approach they love to talk about these days. It also highlights another inconsistency the NZTA run with. You may recall in the debate before the current works were started we and others called for a busway along SH16. At the time the NZTA hid behind the then Auckland Regional Council’s Regional Land Transport Strategy (RLTS) which only suggested bus lanes alongside the motorway. That’s not the same situation with this section though as the route from Lincoln Rd to Westgate and beyond were included as part of a possible future Rapid Transit route between Henderson and Constellation Drive.
One aspect I am a little surprised about is that the NZTA are only going to upgrade the interchange as it is and that they’re not going to add north facing ramps.
As part of this now rapidly approaching project the NZTA are going to hold a few open days – note: these aren’t consultation, more just “here’s what we’re building”.
Come along to one of our open days where you can learn more about the project and talk to the project team.
When: Saturday 14 November, 10am – 2pm
Tuesday 17 November, 4pm – 7pm
Where: Royal Road School Hall, 112 Royal Road, Massey
They say that in time for the open days, this day next they’ll update their website with designs and more information about the project.
Lastly while actual construction doesn’t start till next year the timeline the NZTA have put out suggests we’ll start seeing some physical works soon such as removing houses in the way of the widening.
The big winners from investment in high quality urban Transit are of course drivers. They benefit from all the people making the rational decision to choose other ways to get around freeing up the roads for those who need or choose to drive. The numbers choosing to make this shift depends on the quality of the alternatives, as is shown by the huge and ongoing rise in ridership in response to the upgrade of the rail network this decade. A boom in uptake that completely caught officials and transport professionals by surprise. Here is the Ministry of Transport report to the Minister as recently as October 2014:
And of course the road freight industry should understand this too; their productivity will rise with every switch from driving to alternative systems in cities. 77% of all vehicles are private cars, so enabling a reduction in private car use, especially at the peaks, is likely to be more cost effective way of speeding truckies and tradies than spending 10 of billions on more roads which simply incentivise more private driving on all roads. Especially as this spending squeezes out opportunities to invest in complementary networks. This is the contradiction at the heart of the RoNS model, especially for urban areas; using all available funds to induce more driving, because traffic is congested.
Auckland needs better alternatives to driving not alternative roads to drive on. For drivings sake.
From this morning’s Herald, Drive. Dr Anil Sharma, Porsche enthusiast:
Auckland Star April 1973. Back in the Dark Ages it was considered appropriate to near kill the patient in order to help them. In the 1970s Central government transport planners nearly succeeded in killing the Auckland City Centre through the subtle act of flattening its densest and most proximate dormitory suburbs, then cutting it off any still standing from the city, and turning city streets into motorway off ramps. The charm and glory of these multi-year campaigns are still with us today on the beautiful avenues of Hobson and Nelson Sts, the terrible road pattern and wasted landuse of Union and Cook St, and the blighted devalued areas of K Rd and Newton. And of course the violated and severing gullies themselves. The scale of this ‘surgery’ can be seen in this spread.
The accompanying text is fairly flat and informational.
It seems the desire for a Tabula Rasa, a blank slate, like those postwar planners had in Europe, was so great that we made our own ‘bombsite’.
Happily now we live in more enlightened times and the next city surgery of scale will be much more sophisticated, the City Rail link which as an incision compared to this earlier work is laparoscopic; minimal invasive surgery. No need to maim the patient. Once done no one will even see it, except for that high value resource of people flooding on to city streets not in a car looking for a parking space. And will supply at least as much capacity as the three motorways that meet at this point do today*. So the CRL will double the accessibility to the nation’s most concentrated, biggest, and highest value employment centre, and fastest growing residential area, seamlessly. After the recovery from a few precise cuts, that is.
*Show your work, as Peter always says:
CRL 24 trains per hour each way 750 per train [not crush load; that’s 1000] ~ 36k [crush 48k]
M’ways 12 lanes @2160 [1800 vehicles @1.2 occupants] per lane hour ~ 26k
Of course the buses on the Bridge land some 9000 souls currently too.
We were rightly dismayed when the previous Transport Minister vetoed the desperately needed extension of the famously successful Northern Busway as part of the big spend up on SH1 on the North Shore. We suspect NZTA were too, as they know that the Busway the single most effective tool for reducing congestion and increasing access and human happiness for the travelling public on this route. And is a vital part of the booming Rapid Transit Network. Additionally this extension surely also helps streamline the general traffic lane design through the SH1/SH18 intersection and beyond. NZTA must be keen to not have to factor in growing numbers of merging buses from shoulder lanes etc.
So we are very pleased to find that the agency has found a way to return this logical part of the project to the programme and out of the shadow of ministerial whim [presumably the change of Minister helped?]:
Here is the full document.
Bus users report that their journeys between Constellation and Albany Stations can currently take up a disproportionately large amount of the total trip because of the absence of any Transit right of way; the buses of course are not only themselves delayed but are also delaying other road users here.
The extension will not be a minor structure but as it adjacent to commercial properties it is hard to see how the usual forces of compliant will be able get much traction against it, but it will still need public support at the consultation phase, so Busway users, let yourselves be heard.
We understand the current Busway is built to a standard to enable upgrading to rail systems, we would expect this standard to be continued on this extension, as this does look like the most logical way to next cross the Waitemata Harbour.
Finally, because this is a) spending on the Shore b) not ratepayers funds, and c) not spending on a train or a bike, even the venerable George Wood will be in favour of the proposed extension.
While Auckland remains waiting on the government to commit to its share of funding for the most transformative transport project since the Harbour Bridge – the City Rail Link – the NZTA have just announced that they’ve shortlisted three groups of companies to build the Puhoi to Warkworth motorway as Public Private Partnership.
In the past the NZTA have said the project could cost around $760 million however as PPPs are just glorified hire purchase arrangements it means that over the course of the loan it will cost us considerably more than that. As an example the Transmission Gully project in Wellington costs around $1 billion however after the interest accrued during construction is capitalised it pushes up the cost to about $1.3 billion. That cost is then paid off back to the private companies which the NZTA say will likely be $120-$130 million annually.
That cost might be justified if the current road was heavily used however it isn’t and even the NZTA’s own analysis during the consent hearings admitted it was only really busy a few times over summer. Neither is it the economic saviour of Northland like the government and some other politicians claim. For starters it finishes just north of Warkworth and from there north traffic is normally around 10,000 vehicles per day. Also if this new road was really going to make a difference in connecting Northland with the rest of the country then why hasn’t the existing toll road done that, or even the extension that got the motorway to Orewa/Silverdale in the early 1990’s.
Unfortunately we’ve not been allowed to see the business case for the project as in the past when asked the NZTA they’re keeping if secret until after they’ve awarded the tender.
Here’s the press release:
The NZ Transport Agency has today taken another step towards building the new Pūhoi to Warkworth motorway by announcing the consortia shortlisted to progress to the next stage of the project.
Transport Agency Chief Executive Geoff Dangerfield says the building of the motorway is a significant step towards improving the safety, reliability and resilience of State Highway 1 between Northland and the upper North Island freight triangle of Auckland, Waikato and Tauranga.
In September 2014, a Board of Inquiry confirmed approval of the Transport Agency’s application for designation and resource consents for the project. This was followed, in May 2015, by the Cabinet approving an application by the Transport Agency to procure the motorway through a Public Private Partnership (PPP).
The Cabinet approval came after the Transport Agency determined, following an extensive business case analysis, that the project met the Treasury’s criteria to be procured as a PPP.
The consortia shortlisted to receive a Request for Proposal (RFP) for the financing, design, construction, management and maintenance of the Pūhoi to Warkworth project under a PPP are:
- Northlink – made up of Cintra Developments Australia Pty Ltd, InfraRed Infrastructure III General Partner Ltd, John Laing Investments Ltd, Ferrovial Agroman Ltd, Fulton Hogan Ltd.
- Northern Express Group – Made up of Accident Compensation Corporation, HRL Morrison & Co Public Infrastructure Partners, Acciona Concesiones S.L., Fletcher Building Ltd, Macquarie Group Holdings New Zealand Ltd, Acciona Infrastructure Australia Pty Ltd, The Fletcher Construction Company Ltd, Higgins Contractors Ltd.
- Pacific Connect – made up of Pacific Partnerships Pty Ltd, VINCI Concessions S.A.S., ACS Infrastructure Australia Pty Ltd, Aberdeen Infrastructure Investments (No.4) Ltd, Leighton Contractors Pty Ltd, HEB Construction Ltd.
Mr Dangerfield says the announcement of the shortlisted consortia comes after a rigorous evaluation and selection process.
“We are very fortunate to have such high-quality companies and organisations showing an interest in the Pūhoi to Warkworth project. All of these companies and organisations have sound experience in delivering large infrastructure projects.
“I’m confident that any of these consortia can deliver a high-quality motorway which will provide greater resilience, improved road safety and journey time reliability, and a better connection for freight, tourism and motorists.”
Mr Dangerfield says the RFP will be issued to the shortlisted consortia later this month and the Transport Agency expects to announce a Preferred Bidder by mid-2016.
Subject to successful contract negotiations with the Preferred Bidder, the PPP contract for the project is expected to be awarded in October 2016.
He says the Pūhoi to Warkworth project seeks to procure a PPP contract that would deliver a value-for-money motorway which will assist economic growth in Northland.
“A PPP contract will likely see the PPP consortium manage and maintain the motorway for the 25 years that will follow the anticipated six-year period to build it.”
“PPPs are a particularly suitable procurement method for delivering great results for large-scale and complex infrastructure.
“Using a PPP for key infrastructure projects will open the door for private sector innovations that are not always achievable under traditional public sector procurement methods.
“PPPs allow specific outcomes to be established and measured – and for risks to be identified and transferred to the private sector.
“An outcomes-based PPP for the Pūhoi to Warkworth project will also allow great flexibility within the designation to achieve optimised innovative outcomes.”
Mr Dangerfield says that under a PPP, full ownership of the motorway will always remain with the public sector.
“The nature of the contract to be used will provide a strong incentive for the successful PPP consortium to deliver the best possible results for road users.”
Tentatively, construction of the Pūhoi to Warkworth motorway, under a PPP arrangement, could possibly start in late 2016 with the road completed and open by 2022.
Mr Dangerfield says no decision has been made on tolling for the Pūhoi to Warkworth route but should the motorway be tolled, the Transport Agency would retain responsibility for tolling.
“The public would be fully consulted on any tolling proposal which must also obtain Ministerial approval,” he said.
He says the Transport Agency will continue to consider PPPs for other large-scale and complex infrastructure projects which could potentially benefit from the innovation and value-for-money that can be achieved through a PPP approach.
The first state highway in New Zealand to be delivered through a PPP is the Transmission Gully (MacKays to Linden) project in Wellington.
In July 2014, the Transport Agency signed a PPP contract with the Wellington Gateway Partnership (WGP). Work on Transmission Gully began in September last year, and the motorway will be open for traffic by 2020.
