People sometimes worry that investors (or foreigners) are buying up properties and leaving them empty, speculating on capital gains instead – but if this is happening at all, it seems to be on a very minor scale. In a post last year, I looked at unoccupied homes in Auckland and other NZ cities, using census data. Most of them, including Auckland, had similar percentages of unoccupied homes – roughly 5% to 8%.
In this post, I’ve dug deeper, looking at the unoccupied homes figures for each Auckland suburb. I’ve also put together an interactive map showing the percentage of unoccupied homes for each area:
Across the Auckland region, there were 33,201 unoccupied dwellings on census night 2013. This sounds like a lot, but as per my earlier post, the fraction of homes that are vacant is pretty similar to other NZ cities, and to the other ‘snapshots’ taken in the 2001 and 2006 censuses.
Unsurprisingly, there are plenty of vacant homes on some of our offshore islands – Kawau, Great Barrier, Waiheke, with around 2,500 between them. Most of these, of course, are used as baches.
Most of the other ‘ghost areas’ are also bach hotspots – the highest percentage of vacant homes are in places like Leigh, Omaha, Snells Beach, Waiwera and Point Wells. Around 2,700 vacant homes are in these northern holiday/ lifestyle areas.
Still, most vacant homes in the Auckland region are in the urban area. This is what we’d expect given that’s where most of Auckland’s 507,000 dwellings are.
Within the city, Hobsonville stands out as an area with a lot of empty homes, presumably because many of the homes have just been built and not yet occupied. In fact, the Hobsonville East area unit had 363 occupied dwellings, 120 unoccupied, and another 18 under construction. That construction figure seems implausibly low, so my guess is that many of the “unoccupied” homes hadn’t actually been completed and certified yet, even if they looked habitable.
Auckland Central has 2,200 unoccupied dwellings, according to the 2013 census. It’s quite common for CBDs to have lower occupancy rates, due to several different factors:
- With a ready market of people wanting to stay in the CBD for a night, a week or a month, apartments are more likely to be rented out as short-term accommodation than a house in the suburbs
- Some people can afford to keep a CBD apartment for weekday or occasional use, and spend the rest of the time in a house elsewhere in Auckland, or somewhere else in New Zealand, or even overseas.
- Although legally everyone is supposed to fill out a census form, not everyone does. The ‘response rate’ is likely to be lower in the CBD (language barriers, privacy desires, age cohort factors etc), plus it’s harder for the census collectors to tell whether an apartment is occupied or not, compared to a house. Some apartments will have been incorrectly tagged as ‘unoccupied’.
In my previous post, I quoted North & South magazine, who give “Mt Albert and Mt Eden, Grey Lynn and Herne Bay” as examples of suburbs where ‘ghost houses’ are apparently common. But the census data doesn’t show that at all. Most of these suburbs are spectacularly normal. They have vacancy rates at very typical levels, in line with the averages for Auckland and other NZ cities. Herne Bay is slightly high at 9.1%, but it was 9.3% in 2006 and 7.9% in 2001. And those ‘higher’ rates seem to be typical for the wealthiest suburbs – Remuera is similar.
I initially thought that wealthier suburbs might be more likely to have unoccupied homes – since people living there might have more mobility, travelling overseas for example. However, there’s no evidence of this in the data. I’ve done a few really basic regressions, all of which fail to show a relationship between incomes and the percentage of unoccupied homes. Here’s one example:
Finally, I’m open to the idea that the number of empty homes has crept up since the 2013 census – that this is becoming an emerging issue – but it doesn’t seem likely. We’re not building enough homes, and there’s plenty of demand from people looking for places for to live (giving rise to issues like overcrowding). If anything, there’s more incentive to rent out an empty house now than there was in 2013. My two cents is that we need to put our energies elsewhere if we want to get the housing market into better shape.
New Zealand isn’t the only place to be concerned about empty homes. This article from Sydney uses 2011 census data for the city, similar to what I’ve done here. And this article from Melbourne uses a methodology I quite like – they’ve estimated the number of empty homes, based on homes with abnormally low water usage.
It’s been a little while since I wrote a “Development Update” post, and a lot has happened since then:
- The final batch of Special Housing Areas was approved.
- Downtown Shopping Centre has closed, and is about to be demolished. Tunnels for the City Rail Link will be built underneath, and the site will be redeveloped as Commercial Bay, an office tower and shopping centre.
- Speaking of the City Rail Link, it’s is now officially under construction.
- My count of homes which are currently “under construction” keeps edging up – it’s now up to 6,000, and that’s just for Auckland apartments and terraces.
- Several major buildings have been completed, including Urba Residences (144 apartments just off K Road), Unilodge on Whitaker (300 student apartments) and VXV Three (offices in Wynyard Quarter). Vinegar Lane keeps ticking away, with Countdown also open as of today.
- A number of new homes are now being marketed, such as NXN Apartments, Nugent Rise, The Eight, Eden Green and The International.
So, quite a bit then, and it’s all in the RCG Development Tracker, along with a host of other information on 700-odd projects.
It all adds up to a pretty big ‘pipeline’ of homes which are recently completed, under construction or being sold off the plans.
The tricky part is that, as I’ve written previously, the construction sector is getting really stretched. That’s worth a post of its own, which will happen in the next week. In the meantime, the government keeps finding it politically convenient to blame the Council for all of Auckland’s problems. Convenient it may be, but it’s not particularly helpful for Aucklanders.
Unfortunately, based on “building consent” numbers, Auckland has actually gone backwards in the last couple of months, in terms of the number of homes approved for building.
9,353 homes were consented in the year to April 2016, down from 9,534 in the year to February. The main reason is that apartment consents are volatile, and have had a couple of bad months. It’s a different picture than the top graph shows – that’s more of a “leading” indicator in a sense, so consents should come back up again.
None of it is enough, though, and if you want a bit more evidence:
- The Auckland Plan target is for the city to build 13,000 homes a year over the next 30 years.
- That includes an average of 10,000 homes a year in the first decade, which started in 2012 so we’re already playing catchup on that. Plus, as per the graph above, Auckland has only ever achieved 10,000 homes a year a few times, and that was when we were building far more apartments than we are currently.
- I’ve recently done some calculations that Auckland needs to build 14,000 homes a year to meet current demand (with immigration at its current high levels).
- We’d need at least 16,000 homes a year if not for the fact that Aucklanders have also been moving to other parts of New Zealand, which partly balances out the immigration from overseas.
- Most economic commentators think Auckland already has a shortage of 20,000 to 50,000 homes, which will take many years to address.
This is a huge challenge, although it probably looks pretty good if you’re a builder!
Housing issues in Auckland have become a fairly constant news piece in recent years and the affordability issue has become louder and louder. And it’s not just people wanting to buy a house either but also for renters as rental prices rise too, something that is particularly tough for those on low incomes.
We know that one of the key tools to helping unlock development in Auckland is of course the Unitary Plan – depending on what final form it takes. It reached a new milestone last Friday as the Independent Hearings Panel held its final hearing on it. The amount of work the panel has undertaken has been significant. There were 9443 submissions and 3951 further submissions. The hearings began in September 2014 and there have been 242 days of hearings and there were more than 10,000 pieces of evidence.
Between now and July they’ll be working on their final recommendations to the plan which will be voted on by the council. With elections coming up it’s anyone’s guess as to which way councillors will vote. One thing that does seem clear though is that pressure is increasing on them from the government, in particular Housing Minister Nick Smith.
On the weekend he told by both TVNZ’s Q&A and Newshub’s The Nation that he will be imminently releasing a National Policy Statement (NPS) under the RMA which will put pressure on the growing councils like Auckland to open up land.
“Next month I will be producing a national policy directive under the [Resource Management Act] that will put far tougher requirements on growing councils to ensure they are freeing up long-term the land that is required so that we don’t get into the sort of juggernaut that has been at the core of the unaffordable housing problems in Auckland.”
At first blush that sounds similar to the “throw open the gates” type statements he made when he was made housing minister however since that time he seems to have moderated some of his comments and gained a better understanding of some of the finer issues such as density restrictions that prevent intensification. As such I am hopeful that the NPS he’s developing will also address these constraints too.
I also hope the government consider the impacts on infrastructure as part of any policy. Just throwing open the land might sound like the immediate solution but that land also needs infrastructure to support it and that isn’t cheap. The Council, Auckland Transport and NZTA have been working on the Transport for Future Urban Growth which is planning for about 110,000 dwellings on greenfield land and just the major infrastructure is likely to cost around $8 billion.
Yesterday Smith also became a bit more personal calling Councillor Mike Lee a NIMBY, a hypocrite and part of the problem for opposing intensification in Herne Bay.
“Mike Lee is guilty of Nimbyism,” said Dr Smith.
The Government has designated the site of the old Gables pub a “special housing area”. That allows for fast-tracked development, with between four to seven of the apartments “affordable housing”. It’s about getting more housing into inner-Auckland’s “urban intensification”.
But neighbours don’t like it, and, local councillor Mr Lee is on their side. Mr Lee wrote earlier this year, saying the development was “overriding the civil rights of neighbouring property owners”.
Dr Smith responded, saying he found Mr Lee’s position “ironic”, “odd” and “part of the problem”.
“We cannot have that sort of Nimbyism. That’s at the core of where Auckland has gone wrong. That’s why I’ve politely written back to Mr Lee and said ‘actually, you are being a hypocrite’.”
Unfortunately, in many ways Nick Smith is right, over the last few years Mike Lee has fairly consistently voted against rules that would enable more housing, especially in the in inner suburbs.
John Key is also threatening the council and at his weekly press conference yesterday said:
The Prime Minister also warned that the Government would not be able to “sit back” if Auckland councillors did not deliver enough houses in the city.
Asked to elaborate, Mr Key said ministers would make announcements in this area soon.
Could the government ultimately force the Unitary Plan through if the councillors don’t approve it or worse could they install commissioners?
While I don’t agree with everything they’ve said, one positive is that the government have made some better noises around some housing issues. In saying that they also remain very quick to blame the council for the current issues when they need to take a share of the blame too. The reality is the Unitary Plan process is one the government created and more so, some of the ideas like an NPS could have been pushed years ago. Other tools that they’ve implemented such as the Special Housing Areas have resulted in at least some developers using it as a tool for to increase the value of their land-banking.
The bad news is that even if the government and council’s all do their bits well, our housing issues are something that could take decades to resolve. We’ll now have to await with interest to see what comes out of the budget and out of the NPS the government are preparing.
Through my employer RCG, I’ve just put out a research piece giving 2017 as the first time that Auckland will build more attached homes (apartments, terraces) than detached houses.* This is one milestone, but really it’s just one of the ways in which Auckland is changing to become more city-shaped, as Patrick puts it. While the number and percentage of attached homes will bounce around, I believe that they’re increasingly important for Auckland’s growth, and in the long term they’ll make up at least 50% of the new homes we build.
That doesn’t mean that leafy suburbs will be razed wholesale, or that we’ll stop building detached houses, or that everyone will be forced to live in an apartment. According to the 2013 census, Auckland has:
- 332,000 detached houses
- 50,000 units in buildings with 1 storey
- 43,000 units in buildings with 2-3 storeys
- 16,000 apartments in buildings with 4+ storeys
Clearly, detached houses aren’t going anywhere – it’s just that they’ll be joined by more flats, terraces and apartments too. That means more housing choice.
Housing choice is a good thing, but to bring it back to transport: Auckland needs better public and active transport so that it can handle more people, living closer together, without just getting more and more congested. The city needs transport choice as well as housing choice. We’ve often talked about Flat Bush as an area which has denser housing – including plenty of terraces and low-rise apartments – but which has very poor provision for public transport. That’s a recipe for traffic jams, long commutes and worse outcomes across the board. The new growth nodes in the future – Hobsonville, Massey, Takanini, Silverdale – need to avoid these mistakes.
The (Very) Big Picture
I try to get a bit ‘big picture’ with these posts, but I want to zoom out even further right now: let’s look at the overall New Zealand construction sector. At the moment, it’s as busy as it’s ever been. Statistics New Zealand measures the amount of “building work put in place” each quarter, showing how much construction is occurring. They say:
“For the December 2015 quarter compared with the September 2015 quarter, after price changes and seasonal variations are removed… total building activity rose 2.5 percent… the trend for all building work grew 1.8 percent, and is at its highest level since the series began in late 1989”.
There are regional differences – Canterbury construction will be tapering off in the next few years as the earthquake rebuild continues, and Auckland construction is booming. On the whole, though, the construction sector is pretty much flat out. Forecasts like the National Construction Pipeline Report, and the latest information on building consents, suggest that the outlook for the next few years is very busy too.
Growing industries are meant to be a “good news” story, and they are, and this means more jobs and more economic activity and all the rest. But it’s not without issues, because the construction industry relies on having a trained workforce, and it’s hard to keep growing the industry at 5% or 10% or 15% a year when construction is already a pretty big part of the economy and most of the people who know how to swing a hammer are already swinging.**
The graph below, from the Household Labour Force Survey, shows the number of people employed in construction at an all-time high:
Many builders are running at capacity already, and there are probably some specialist areas where it’s almost impossible to find builders to take on new projects – or at least, without paying through the nose. Peter’s looked at these issues in road construction previously, and I’ve heard that some Auckland apartment developers are struggling to find builders as well.
So, one issue with a very busy construction industry is that prices go up. Another worry is that there’s less focus on quality control, potentially resulting in buildings which aren’t up to scratch. It’s certainly something the industry, councils and government need to keep a close eye on.
Phew. So that’s the very big picture. It’s a good time to be a builder, but it’s going to be hard to find all the construction workers, tradesmen, consultants and other workers needed in the next few years, and hopefully the quality of the build isn’t compromised.
* Technically, we’re predicting 2017 to be the first year that more attached homes get building consent than detached houses. It will probably be 2018 or 2019 before Auckland completes more attached homes than detached houses.
** A hammer, that is.
Auckland’s population keeps on growing, with a hearty mix of migration and wee bairns. And with that comes demand for development of all kinds. Residential gets most of the attention, and fair enough too: we’re still struggling to build enough homes for everyone who wants to live here.
The Auckland Housing Accord between the government and council is into its third year. I’m eagerly awaiting the release of Auckland Housing Accord Monitoring report #9, hopefully by the end of this month. Will it be a riveting read like Auckland Housing Accord Monitoring report #8, or prescription medication for insomniacs like Auckland Housing Accord Monitoring report #5? Find out right here on TransportBlog.
Seriously, though, getting new homes built is a pressing issue for many reasons. And one of the main tools in the Housing Accord is identifying “Special Housing Areas” where approval processes can be streamlined and new zoning can be used.
The latest ‘tranche’ of SHAs was announced earlier this month, and as with all the other tranches, the urban/ infill/ apartment/ terrace ones have been mapped in the RCG Development Tracker, along with another 600-odd developments in many sectors.
The council has closed off requests for new SHAs, so that they can focus on the requests they already have. With the legislation set to expire in September, there’ll probably be just one more tranche to come.
Building consents are the best measure of how many homes are being built, or about to be built.
In Auckland, 9,251 homes were given building consent in 2015, up 21% from 2014 (7,632 homes). This is progress, but those numbers need to keep growing – to at least 13,000 a year, or even higher to start chipping away at the undersupply.
Down in Canterbury, home building activity is tailing off. Christchurch is still a little way off replacing all the homes lost in the earthquakes, but it’s getting there. The number of building consents peaked in 2014 at almost 6,700 homes were given building consent in 2014, and that’s fallen back to 5,800 for 2015. Many construction workers will look to move up to Auckland where there’s still plenty of demand for new housing.
A year ago, I wrote that “Australia is currently in the middle of a major apartment boom“. Well, the boom is still going – in fact, it’s risen to even higher levels. On a ‘moving annual total’ basis, Australia has gone from approving 86,000 attached units a year to 113,000, an all-time record.* That’s helped push total dwelling approvals to 229,000, also an all-time record.
There are concerns in some quarters that there might be a looming oversupply of apartments in some areas, as noted by the Reserve Bank of Australia. I don’t know enough about the Aussie market to comment, but it’s certainly a reshaping of the market given the amount that’s being built. Speaking of reshaping, Patrick’s post the other day showed how the apartments will change the Melbourne CBD skyline (well, showed how one part will change, I’m not sure if it’s as drastic for other areas).
Back in New Zealand, building consents continue to rise, but not to the same extent. My view is that there’s a lot more growth to come, especially for attached dwellings,** and especially in Auckland. Keep an eye out for this over the next few months.
Lastly for today, here’s an update on the percentage of new dwellings which are attached, for both Australia (which has reached an all-time high, of 49.5%) and New Zealand.
As per last year, I’ll follow up soon with a post looking at the trends in different cities. But I think the trends above for Australia are pretty impressive in their own right.
*Technically, the Australian approvals are for “dwellings excluding houses”. That covers apartments, terraces and so on.
** Statistics New Zealand have changed their categories since last year. I’ve combined the categories for “apartments”, “townhouses, flats, units, and other dwellings”, and “retirement village units”. Note that some of the retirement villages will actually be detached homes, but they’re not split out in the data.
Last week, I introduced the concept of elasticity of supply with respect to price as a useful measure of housing market dynamics. Supply elasticities measure how responsive builders are to an increase in demand. In other words, when people turn up wanting dwellings, how quickly do the tradies start building more?
Supply elasticity can in turn have a big, long-run effect on prices. If the building sector is consistently slow to respond, it creates the condition for an ongoing shortfall in supply, which means that people will bid up prices more.
My post last week took a look at some of the (limited) international comparisons of planning regulations, which seem to indicate that New Zealand is not an especially poor performer. For example, consent processing time is relatively fast and efficient compared with other OECD countries.
However, regulations are only part of the picture. For example, Patrick wrote a good post a while back looking at Auckland’s geographic constraints:
Intuitively, we’d expect Auckland’s limited supply of developable land to have an effect on housing supply dynamics. But how much of an effect should we expect?
The empirical literature provides us with a reasonable estimate. A 2010 paper by MIT economist Albert Saiz (Massachusetts, not Manukau) measures constraints on land availability in large US cities and uses them to estimate the effect on housing supply.
Saiz finds that there are large differences in land availability between different cities. For example, “flatland” cities like Atlanta or Houston have very little area constrained by lakes, rivers, oceans, or steep slopes. Over 90% of the area around these cities is available for development. Coastal cities like San Francisco, San Diego, or Miami, on the other hand, might be able to develop less than 1/3 of the surrounding area.
Saiz concludes that:
Quantitatively, a movement across the interquartile range in geographic land availability in an average-regulated metropolitan area of 1 million is associated with shifting from a housing supply elasticity of approximately 2.45 to one of 1.25. Moving to the ninetieth percentile of land constraints (as in San Diego, where 60% of the area within its 50-km radius is not developable) pushes average housing supply elasticities down further to 0.91.
Translated from economese, this means that cities with less developable land have housing markets that respond more slowly to increased demand. (Or, as non-economists might say, duh.) For context, an elasticity of 0.91 indicates that a 10% increase in house prices is met by a 9.1% increase in housing supply. Even if regulations are held constant, a “flatland” city is expected to have a more responsive housing market than a coastal city with lots of hills.
In other words, when people compare Houston’s house prices with San Francisco’s or New York’s, they’re not comparing like with like. Geography matters quite a lot!
So what does Auckland’s geography look like? A 2014 NZIER paper modelled the effect of geographic and regulatory barriers on the city’s house prices. The authors conclude that: “relative to even Australian cities Auckland’s twin harbours severely restrict the availability of well-located land close to the city centre.” Overall, they estimate that less than one-third of the area around Auckland is available for development – most of the rest is water:
In other words, Auckland has very severe geographic constraints. In terms of the availability of developable land, it’s similar to hilly coastal cities like San Diego. Saiz estimated that a city of around Auckland’s size with an average level of planning regulations would have a supply elasticity of 0.91. So: does Auckland perform better or worse than this in practice?
A 2010 study by Arthur Grimes and Andrew Aitken provides some relevant data. Using data at a district council level, they looked at how quickly new dwellings were built in response to “shocks” in demand such as increases in net migration. Their key conclusion was that housing supply in New Zealand’s urban areas tends to be a little bit more responsive than supply in rural areas:
If we divide regions into urban and rural, we find faster adjustment in urban areas (average γ1i = 0.0093) than in rural areas (average γ1i = 0.0064). This result is consistent with an active development industry, based principally in cities, facilitating new construction.
In other words, the authors estimate a supply elasticity of around 0.93 for NZ’s urban areas (principally Auckland). This is almost exactly what we would predict based on Auckland’s geography. The implication of this is that Auckland’s housing market functions more or less as expected given its geography – we don’t have to assume unusually restrictive planning regulations to explain the observed outcomes.
There are a couple lessons we can draw from this.
First, Auckland’s geography is a primary driver of the city’s housing supply dynamics. If we have higher house prices than we’d like, it’s partly because we have less land for housing. As I’ve written before, some analyses of Auckland’s high house prices fall prey to omitted variable bias – i.e. ignoring important causal variables and thus over-estimating the impact of specific policies. This can result in flawed policy recommendations.
Second, we shouldn’t compound constrained geography with bad policy. Because Auckland doesn’t have much developable land, there is an even stronger incentive to use land efficiently. (A fact with implications for transport policy, planning policy, tax policy, and publicly-owned land.) Land-hungry policies might not be too bad in a land-abundant place like Houston, but requiring Auckland to follow a similar pattern is economically calamitous.
As most New Zealand cities are also heavily constrained by geography, this challenge isn’t unique to Auckland. But it’s also not all bad: the interplay of mountains, volcanoes, harbours, and oceans is what makes New Zealand such a beautiful place to live. Let’s build cities that enable us to get the best out of it.
How should we think through the dynamics of housing markets?
Conceptually, there’s a very simple answer and a very complex one. The simple version is that housing is just another market, shaped by the interaction of demand – i.e. people turning up with money to buy dwellings – and supply – people building new dwellings to meet demand. Policies can affect the supply side (e.g. by making it more costly or difficult to build new dwellings), the demand side (e.g. by subsidising home ownership), or both (e.g. by imposing supply restrictions to produce local amenities like parks).
And then there’s the complex story, in which we have to think about things like:
- Interactions between owner-occupation, renting, and property investment
- The impact of mortgage lending practices and asset values on housing
- The durable nature of housing, which means that prices can overshoot in a declining market
- The geography of jobs, amenities, and housing supply – not all locations are equally desirable, which means that houses in the wrong place don’t do much good
- Government provision of housing services (e.g. state homes) and subsidies for property ownership or renting
- Industrial organisation in the building sector, including firm size and structure and supply of skilled labour
- A wide range of local and central government regulations covering building materials, performance standards for dwellings, and the bulk, form, and location of dwellings
- Etc, etc, etc.
So it’s not usually possible to fully explain housing market dynamics with a simple supply and demand story. However, it’s often useful to start with a clear understanding of that story.
So with that in mind, here’s a key concept for analysing housing market dynamics: elasticity of housing supply. In an earlier post on public transport fares, I introduced the idea of elasticity of demand, which measures how responsive people’s demand for a good or service is to higher (or lower) prices. Supply elasticities are much same idea, but on the supply side of the equation.
Elasticity of housing supply is an important concept because it provides an indication of how many new dwellings will be constructed in response to an increase in prices (or demand). For example, an elasticity of less than 1 would indicate that developers are relatively unresponsive to increased demand – i.e. if prices rise by 10%, it will cause new housing construction to increase by less than 10%.
It’s easy to see why this is an important metric. In the aggregate, a relatively “inelastic” supply will mean that the housing stock will struggle to meet demand in a growing city. But aggregate lasticities aren’t everything – if new dwellings can’t be built in areas that are proximate to jobs and amenities, bad things will still happen
Supply elasticities can be measured empirically by looking at how markets have evolved in the past. In fact, a number of people have done just that.
In their 2012 housing affordability inquiry, the Productivity Commission surveyed some of this literature (see pages 33-34 of their final report). They published this chart comparing long-run elasticity of housing supply in 21 OECD countries, including New Zealand. Remember, higher numbers indicate more responsive housing supply:
New Zealand’s elasticity was around 0.7 – on the inelastic side, but still within the top 1/3 of the countries in the study. In other words, neither terrible nor fantastic. We have historically had a more elastic supply of housing than the UK or Australia, but we’ve lagged behind several Scandinavian countries as well as Japan, Canada, and the US.
Now, elasticity of supply is influenced by a number of factors. Building industry capability and productivity plays an important role. So do geographic constraints – a topic I’ll come back to in a future post. State house construction can also play a role, by ensuring that building activity doesn’t bottom out when prices dip. And, of course, planning regulations and consenting processes play a role. But how much of a role?
Unfortunately, we don’t have any good international comparisons of planning policies. However, the World Bank’s annual Ease of Doing Business report publishes some data on the ease of obtaining building consents, which provides a rough indication of the stringency of countries’ planning processes.
Here’s the upper echelons of their 2015 rankings. As you can see, New Zealand is ranked as the second easiest place to do business. When it comes with dealing with construction permits, we’re ranked 13th – ahead of countries like the United States (46) and United Kingdom (45) but behind Hong Kong (1), Singapore (2), and, oddly, Iraq (9).
Here’s a bit more detail on how Auckland’s consenting processes stack up. We have fewer procedures, a shorter consenting timeframe, and a lower consenting cost than the average OECD country:
So what does all this data mean? I think there are a few lessons we can – and can’t – learn from it.
The first is that perhaps we don’t have as many problems as we think we do. I have to admit that I was surprised by these figures. I was expecting our elasticity of supply to be lower and our consenting processes to be ranked lower. But perhaps – as with Auckland’s congestion – our problems aren’t that bad when put in international perspective. Kiwis do tend to prefer doing things efficiently, and NZ’s not large enough to require overly cumbersome bureaucratic machinery.
The second thing is that there is room to improve. There is almost always room to improve. New Zealand’s housing supply is still inelastic, which suggests that we may have trouble accommodating growth. Although the World Bank’s data on the ease of obtaining building permits seems to suggest that regulatory processes are less onerous here than many other places, who really knows? There are likely to be gremlins in any bureaucratic process.
The third lesson is that there are multiple paths to a well-functioning housing market. The countries with the highest elasticities of housing supply don’t have a lot in common with each other when it comes to policy frameworks. The US has a different set of policies than Japan or the Scandinavian countries. And it’s also the case that some countries have affordable and livable housing even though their elasticity of supply is low – Germany or the Netherlands, for example.
This is, in a way, really good news. We don’t have to go searching for a single “silver bullet” policy framework. There are different paths we could go down to improve the functioning of our housing market.
What do you make of these comparisons?
AUT’s Briefing Papers initiative has kindly allowed us to syndicate their recent series on housing. The eighth paper is by investor and company director John Walley:
Auckland has a housing problem but this is not just a problem for Aucklanders, or new home buyers. Out of control asset inflation – as seen in the Auckland housing market – is toxic to the real economy, destroying our ability to deliver a long-run neutral balance of trade. High asset price inflation misdirects investment and lowers the competitiveness of the tradable sector resulting in lower average wages and falling returns to trade.
Under current conditions investment is largely focused on assets, not productive enterprise. In an effort to check rises in asset prices, interest rates in New Zealand are higher than other countries. Consistently higher comparative interest rates results in a stronger New Zealand dollar than would otherwise be the case, reducing export returns, competitiveness of manufacturers in our domestic market and lowering incentives to invest (key to future innovation, competitiveness and capability). Inequality is worsened, as house and land values contribute to higher living costs; this further damages our economic performance, as recent OECD research has shown higher inequality to be a drag on economic growth. As house prices rise, indebtedness rises in comparison to earnings, increasing vulnerability to economic shocks that can threaten financial stability.
Ever expanding debt, supported by banks and the large monetary stimulus programmes in the U.S, Europe, U.K and Japan, and even by the Reserve Bank of New Zealand (RBNZ rules favour land and buildings on bank balance sheets), fuel ever higher average house prices with respect to average earnings. This process is supported by the notion that prices will always rise and that debt will be paid by the (tax free) capital gain. The risk to stability is, of course, if prices fall. Research by the OECD estimated when household debt rises above trend by 10 percent of GDP there is a 40 percent chance of the economy entering recession in the following year, compared to 10 percent likelihood when household debt is rising at trend.
More generally, recent OECD research looking at the role of finance and growth suggested the following is the case in most OECD countries: more credit to the private sector slows growth; more stock market financing boosts growth; credit becomes a stronger drag on growth when it goes to households rather than businesses; and bank loans slow economic growth more than bonds.
Auckland house prices are high when compared to incomes. The graph below compares housing affordability (the ratio between median house prices and median annual household income) for each countries’ major markets – for New Zealand, this is the Auckland housing market. As of September 2014, the median house sale price in Auckland was 8.2 times median household income – the survey median was 3.8. The New Zealand national median house price-to-income ratio is also high, at 5.2. Demographia defines income multiples of 5.1 and over as ‘severely unaffordable’.
Household debt reached a peak of 162.2 percent of disposable income in the first quarter of 2015, after previously peaking close to this at 161.2 percent in the second quarter of 2009. New Zealand’s household debt-to-GDP ratio is at 95 percent, down somewhat on the peak of just over 100 percent in 2009. Research by the Bank of International Settlements (BIS) suggest that household debt over 85% of GDP can damage an economy, though greater sensitivity to economic downturns, and by boosting debt for non-productive assets, pulling resources from the rest of the economy to service it, including skills and investment.
This is the problem – for the whole New Zealand economy. Will building more houses in Auckland fix it?
Under-supply of housing naturally leads to higher prices, particularly with high net migration. Hence the solution to this part is to increase supply, open up new land for development, focus on increasing the number of houses built and responsibly reduce constraints and barriers to new builds. It is also important that such developments target high density development, particularly in larger cities such as Auckland, to reduce the cost of urban sprawl (some commentators have called for a debate on migration).
But supply side activity has a limited pace as the allocation of finite construction resources and labour has a limit, made worse when in catch-up mode, as seen in the large deficit in the cumulative net supply position in the graph below – this is a key area for the Government to do more, especially ensuring affordable housing is built. Low rent inflation suggests investors and speculators are contributing to house price inflation.

Supply side efforts take a while to take effect, and the threats to financial stability and the damage to the tradable sector are with us right now. More needs to be done. The supply response in the last two decades has favoured more expensive housing, rather than affordable homes, exasperating the inequality effect.

Intervention on the demand side, such as a register of foreign buyers, borrowing limits related to asset earnings and/or buyer earnings, higher deposits for landlords and capital gains enforcement can act quickly to reduce the growth in debt, slow price rises and thereby improve financial stability.
Other countries have acted:
- Last year the Bank of England reintroduced Loan to Income Ratios, where no more than 15% of mortgages issued can exceed a Loan to Income Ratio of 4.5. If you earn £100,000 a year, your loan would be capped at £450,000.
- The Central Bank of Ireland introduced Loan to Income Ratios, of 3.5 times of gross income and Loan to Value Ratios set at 80% (a 20% deposit is needed) with a lower ratio of 70% for those buying rental properties. For first home buyers this is set at 90% for properties up to €220,000, with 80% on any value exceeding this. This tougher requirement on rental investors reflects their higher default risk as compared with owner-occupied homes.
Research by the BIS suggests that such macro-prudential tools can be effective in slowing house price inflation and mortgage credit growth if they are introduced at a time when these are both high. In other words, they can be most effective in slowing a boom, and are less invasive at other times, keeping the lid on gently.
Another issue often cited as a factor increasing prices is demand from foreign investors. Unfortunately with no register of such ownership in New Zealand it is hard to judge the extent of this.
- Singapore introduced stamp duty taxes on non-resident buyers of property. This tax now sits at 15%, increasing from 10% when it was introduced in 2012. They also introduced a cap on debt repayment costs at 60% of the borrowers’ monthly income. These measures have seen prices fall 4% in 2014, and sales volumes falling.
- Australia: there are proposals to introduce such a register as well as fees on foreign investors: A$5000 fee for property up to A$1m, and investments over A$1m would incur an A$10,000 fee for each additional A$1m purchased. These measures are probably too small to make much difference but are a start. Foreign investors are limited to purchasing new build, and not existing property, and these rules may be strengthened. The state of Victoria is now also planning a 3% tax on foreign buyers of property.
- England, Ireland and Australia also have some form of Capital Gains Tax.
In a recent speech, the Deputy Governor of the RBNZ suggested New Zealand needs fresh consideration around tax settings for housing, particularly for investors, saying “housing is the most tax-preferred form of investment, particularly when it is highly leveraged. Indicators point to an increasing presence of investors in the Auckland market and this is no doubt being reinforced by the expectation of high rates of return based on untaxed capital gains.”
While we have seen positive steps forward by both the RBNZ and Government in addressing these issues, wider reform is needed. Limiting the expansion of private debt to both earnings and equity is important not only for those trying to buy a home, but to reduce the impact on competitiveness of the tradable sector through the exchange rate channel and cost of borrowing. More generally, the Government and RBNZ need to stop shying away from strong demand side changes, being sufficiently bold to tackle hard issues around the treatment of asset debt by the RBNZ, and fiscal policy changes by Government around the capital gains incentives.
In comments to a recent post I wrote reviewing recommendations from the Australian Productivity Commission’s review of public infrastructure investment, reader Brendon Harre raised an important question about transport cost-benefit analysis (CBA). He commented that:
