The interactive maps of the election results hosted on Scoop are a highly addictive tool to play around with. A map that I found particularly interesting runs a comparison of how Labour & Greens did in 2008 and 2011, with how National & Act did in the last two elections. Blue indicates the electorates in which the party vote shifted towards National & Act (obviously, without exception, predominantly to National) and red indicates electorate where the party vote shifted towards Labour and the Greens: You can see that pretty much the entire country shifted, to a great or lesser extent, towards National/Act. Some places more than others of course. Christchurch in particular seems to be an area where voters have shifted to the right over the past three years.
However, Auckland stands out as quite different to the rest of the country – as particularly the west and south of Auckland shifted back quite a lot to Labour & Greens compared to the 2008 results. There was a 9.8% swing to Labour/Greens in Manukau East, 8.8% in Manurewa, 7.1% in Mt Roskill, 6.7% in Mangere and even 4.4% in the National stronghold of Hunua. I’m not quite sure what’s behind this. Changing demographics? Dissatisfaction with the Super City? Perhaps something to do with transport?
