National's Auckland firewall visualised

Auckland has become the National Party's firewall as demonstrated by their ability to either grow or minimise party vote loss across all but five of Auckland's 22 electorates.

What's interesting about this relative to Labour is that it illustrates that Labour has largely taken party vote share from the Green Party to achieve its gains North-Western Auckland, while Labour has hurt National directly in Auckland Central and the directly adjacent electorates of Mt Albert, Epsom, North Shore, and Tamaki.

As shown in my analysis of Labour's failure to mobilise its voters in West and South Auckland, these areas nearly all grew National's party vote share relative to 2014, barring Maungakieie (which only dropped 0.15% points).

In summary:

  • Five electorates lost more of the party vote share for National than their average loss across New Zealand (excluding the Maori electorates)
  • Five electorates lost less than the party vote share for National than the average
  • And 12 electorates actually grew National's share of the party vote, though Hunua and Upper Harbour could easily tip in a the above category once special votes are counted.

The Jacinda effect visualised in Auckland

To win an election in New Zealand you have to win in Auckland and Labour simply didn't do enough winning in the City of Sails. As I wrote last night, Labour's campaign failed completely in West and South Auckland, and only performed well - growing its party vote at or above its average nationally in six out of the 22 Auckland electorates - all electorates that you'd typically define as relatively urban and/or affluent.

Conversely, of the 12 electorates where National actually grew its party vote across the country on Saturday night, they run in a corridor starting in Upper Harbour and running through West and into South Auckland.

Where Labour did particularly well is in Mt Albert and Auckland Central which almost certainly has to do with Jacinda Ardern. In Mt Albert the result will have been bouyed by her being the local MP as well as Labour Party leader, and voters generally tend to reward that (though not always). In Auckland Central I suspect what we're witnessing is similar to what was seen in Wellington Central, where there wasn't so much as a youthquake, so much as a youth seismic swing, where youth voters (defined as those 34 and under), and especially students, have switched their votes from National and particularly the Green Party, in behind Labour.

Once we get special votes in and enrolment numbers for those electorates, it'll be interesting to see how it changes, and whether there was increased enrolment and turnout in student heavy electorates, or just a wave of students switching their votes between parties.
