Last week Statistics NZ released their provisional population estimates as of 30 June 2015 and there were some interesting results.
All regions in NZ with the exception of the West Coast saw their population increase with the largest increase both in total number and in percentage occurring in Auckland. In total Auckland’s population grew by 2.9% or 43,600 people. That’s not the largest percentage increase Auckland has seen but in terms of the number of people, it the largest increase the region has experienced since 1996 and probably the largest ever. In total growth in Auckland accounted for at least half of all growth in New Zealand (1.9% or 87,000 people) with the next fastest growing regions being Canterbury with 2.1% and Waikato with 1.9% with Bay of Plenty and Otago at 1.7%.
The chart below shows the percentage growth in each region and as you can see Auckland is clearly an outlier compared to other regions.
The regional growth doesn’t mean there isn’t some strong localised growth occurring. Stats NZ point out that at a Territorial Authority level there are a few areas growing faster than Auckland, they are Selwyn up 6.5%, Queenstown-Lakes up 4.9%, Waimakariri up 3.6%. None of those can hold a candle to the Waitemata local board though, more on that soon.
Having both the largest population and it’s also being the growing the fastest region means Auckland now contains more than 34% of all of New Zealand’s population, that’s up from around 30% in 1996. Below is the change in Auckland’s population since then.
Within that growth Stats NZ say that migration has played a big role in recent years. Of the extra 43,600 people in Auckland they say 14,500 came from natural increase while 29,100 were from people migrating either domestically or internationally. By comparison last year had 14,200 from natural increase with 19,600 from migration.
While Auckland is definitely growing strongly that growth isn’t occurring evenly with some notable differences at a local board level. The stand out in this area is the Waitemata Local board which grew a whopping 9.7% or 8,400 people in a year after growing by 6% the year before. Other than Waitemata the other local board areas to see a high level of new residents includes Howick, Hibiscus and Bays and Albert Eden.
It’s amazing just how much the Waitemata Local Board area was able to grow in one year but where did all of those people go? Looking further we can find that more than half of it (5,460 out of 8,400) went to the CBD area – as defined by the Ministry of Transport for their CRL Targets – which is shown below. In fact combined the two area units in the middle – Auckland Central East and West – had a larger increase in population than any of the local boards (4,100 combined).
The best suggestion I’ve heard for such a strong increase is the result of a large number of overseas students after a number of years of lower numbers coming here. Considering that over the last year there hasn’t been a huge number of apartments completed it perhaps suggests there has probably been a number of empty apartments tenanted and an increase in the occupancy of some apartments. The increase saw the city centre population reach over 41,000 people, over 8 times what it was just under 20 years ago. The impact of all of these extra people has been enormous in making the city centre more vibrant and liveable, I’d suggest there’s a positive feedback loop at play.
