Auckland’s population is estimated to have increased by nearly 43,000 in the year to June, with two thirds of the increase coming from migration.
That means Auckland’s estimated housing shortage has increased by around 25,000 since 2012, and is continuing to grow.
Statistics NZ estimates Auckland’s population grew by 42,700 in the 12 months to June, with the net gain from migration accounting for 28,900 (67.7%) and the natural increase in the population (the excess of births over deaths) accounting for 13,800 (32.4%).
The migration figures include growth from people moving to Auckland from overseas and those moving to Auckland from other parts of New Zealand.
While migration is still accounting for the bulk of Auckland’s growth, it was lower than it was in the 12 months to June 2015 and 2016, while growth from the natural increase in the population was higher, although the differences were small (see graph below).
The numbers also suggest that Auckland’s housing shortage is continuing to worsen, with interest.co.nz estimating that 14,233 new dwellings would have been required to house the region’s population growth in the 12 months to June (based on average household occupancy levels), but only 10,364 were consented, leaving a shortfall of 3869 homes.
The table below plots the trend in Auckland’s population growth versus the number of new homes being consented since 2012.
It shows that the shortfall in new housing stock worsened dramatically in the 12 months to June 2014 after the former National government loosened the rules on immigration.
And the housing shortfall has accumulated every year, increasing to almost 25,000 homes by the end of June this year.
That estimate could be on the low side, because the building consent figures make no allowance for existing homes that have been demolished to make way for new ones, or homes that were consented but never built.
The figures show the enormity of the problem confronting the new Labour-led government as it tries to tackle the housing crisis it has inherited from its predecessor.
The figures also suggest that Auckland’s housing shortage will continue to worsen unless there is either a significant drop in migration into the region, or a substantial rise in the number of new homes being built.
Net migration in to the region would need to drop back to just over 17,000 a year for the number of new dwellings being consented at current rates to match the increased demand for housing.
But that would do nothing to reduce the existing accumulated shortfall.
So even if there is a combination of reduced immigration and an increase in the construction of new homes, it’s likely to be many years before demand and supply for housing in Auckland get back into any sort of equilibrium.
