Over the holiday break we’ll dig into the archives a bit. This post by Matt was originally published in February 2015.
Late last week Statistics NZ released their latest regional population projections from 2013 through to 2043. It once again highlights just how much growth is expected to occur in Auckland with them projecting roughly an extra 500,000 to 900,000 people in the region within 30 years – that’s a 36-63% increase on what we have today.
All 16 regional council areas are projected to increase in population between now and 2028, Statistics New Zealand said today.
“The short-term trend partly reflects the current high level of arrivals into New Zealand, and the current low level of departures,” population statistics manager Vina Cullum said.
“However, population growth will slow in the longer term as our population continues to age. This will see the number of deaths increase relative to births. Also, net migration (arrivals minus departures) exceeded 50,000 in 2014 and is unlikely to remain at that level.”
Auckland will continue to be New Zealand’s fastest growing region, and account for three-fifths of the country’s population growth between 2013 and 2043. From an estimated population of 1.5 million in 2014, Auckland is projected to reach 2 million in the early 2030s. That means out of every 100 people in New Zealand, 34 currently live in Auckland, but this will increase to 37 in 2028 and 40 in 2043.
Natural increase (births minus deaths) is projected to account for three-fifths of Auckland’s growth, and net migration the remaining two-fifths.
Of New Zealand’s 67 territorial authority areas, 51 are projected to have more people in 2028 than in 2013. However, only 30 are projected to have more people in 2043 than in 2028.
The fastest population growth between 2013 and 2043 is expected in Selwyn and Queenstown-Lakes districts, up an average of 2.2 and 1.8 percent a year, respectively.
The projections are not predictions, but an indication of the size and composition of the future population. Statistics NZ produces low, medium, and high growth projections for every local area every 2–3 years to assist planning by communities, local councils, and government.
You can see the annual projected growth for each region below. As you can see the growth Auckland is leaps and bounds ahead of anywhere else and the only region to even come close is Canterbury and only if it sees the high projection outcome.
Of course when you look at the change on an actual number basis Auckland’s expected growth is even more extreme. This is based off the medium projection. Due to most regions being a fairly similar size it can be hard to tell them apart. In Canterbury, the vast majority of projected growth will happen in the Christchurch City Council area or in the two surrounding districts – Selwyn and Waimakariri. I think that is going to make it increasingly important for the region to start looking at some rapid transit options – unless it wants to follow Auckland’s mistakes.
Another way to show the level of growth in Auckland in particular is below. This is the projected cumulative growth from 2013 to 2043 for Auckland and the rest of the country. Auckland grows by over 730,000 people while the rest of the country by only around 460,000 – of which about 80% is in Christchurch, Wellington, the Waikato and the Bay of Plenty.
Every time the issue of Auckland’s strong growth comes up many people highlight the challenges it adds, in particular the cost of new infrastructure and housing however I feel it’s also worth remembering that it presents a lot of opportunities too. Instead of trying to cap the city’s growth like some have suggested in the past we should embrace it as that will not only make the city stronger but also help make the country as a whole stronger.
One question people often have is how realistic these projections are and how past projections turned out. As it happens Auckland tends to track slightly ahead head of the medium projection. Here’s what was predicted to occur from 2001 – 2026 – the blue area represents the range of low, medium and high growth projections.
Stats NZ have also made predictions within Auckland down the local board level and in many ways this provides a more interesting and useful look at how the city is changing. Like we see nationally, there are expected to be some areas that grow much stronger than others and one of those is the Waitemata Local Board area which covers the city centre and inner suburbs. Population in the area is expected to almost double from 2013 around 81,000 to 152,500 which if it occurs would make the Waitemata Local board area have the third largest of any board in Auckland.
In addition to the City Centre the local boards that are likely to see a lot of greenfield development are also high on the list.
