Too many costly homes
Table 1. National housing affordability for households earning 80% of median household income.

While more new houses are going up, they’re not necessarily ones that middle and low-income New Zealanders can afford, leaving the housing affordability crisis unresolved.
NEW ZEALAND IS BUILDING more homes now than it has in the last 45 years. This is critical to make up the housing supply deficit of recent years, but as Ireland and other jurisdictions overseas have found, building more houses is not the same as building houses affordable to middle and low-income households.
58% of new homes in top 25% of prices
It is well established that New Zealand’s building industry has been moving upmarket with higher and higher proportions of dwellings built in the top 25% of house values. That rush to building high-value housing rather than low-cost housing has been particularly pronounced since the 1990s. By 2014, almost 58% of house new builds were in the highest quarter of house prices. The housing crisis partly reflects that reduction in low-cost housing production.
Price increases even when supply is up
Increasing dwelling production per se does not generate low-cost houses that are affordable for households. For those using simple supply/demand models to understand pricing, this seems counter-intuitive. Surely if supply increases, house prices will drop?
There are lots of reasons why this is not the case that are outside the ambit of this article, but some examples demonstrate the point.
First, New Zealand saw a sharp increase in house prices in 2003 even in regions characterised by likely depopulation.
Second, even in markets seen as most undersupplied, such as Auckland, there has been a surplus of new dwellings relative to household growth.
Shortage of low-cost houses
In an article in www.interest.co.nz, Auckland University’s Michael Rehm also notes that, while over 99,000 new dwellings were built in Dublin between 2002 and 2007, a 27% increase in stock, house prices increased significantly over that time. It was only the global financial crisis that brought a subsequent decline in house prices.
Homelessness, more households with multiple unrelated people as well as house-holds composed of multiple families or families and others and houses persistently empty despite unmet housing needs indicate the low-cost segment of the housing stock is underserved by new builds.
Struggle for low and middle-income households
Associated with the limited production of low-cost new builds has been the development of widespread affordability problems across low-income and middle-income households.
This is particularly the case for those households classically defined as in need of affordable housing – those with incomes at or below 80% of median incomes.
Before 1991, low-cost new builds affordable
Those households were able to afford lowcost new builds in the period prior to 1991. Now they struggle to find affordable housing.
In 1966, a household on 80% of median household income would have typically been buying a low-cost home at a house price to income ratio between 3.5 and 3.9. By 2013, that house price to income ratio could be expected to range from 7 to 9.3 (see Table 1 above).
Outgoings now around half of income
For an 80% of median household income with a 25-year mortgage, the outgoings in 1966 required to service the purchase of a low-cost new build could be expected to be in the region of 21–24%. Increasing house prices are reflected in significant housing cost exposure even when interest rates look fairly similar.
Consequently, in 2013, even a lower-quartile value new build at similar interest rates to those prevailing in 1966 would confront a lower-income household with outgoings between 43% and 56% of income.
Median-income households under housing stress
Issues of affordability affect not only those on 80% of median household incomes (see Table 2). Households on median incomes are showing housing stress in 2013 compared to 1966, even when purchasing at the lower quartile of house/section new builds.

These differences do not reside in more constrained planning regulations, although arguably planning permissions have been more complex and less certain in the post-Resource Management Act period.
Nor, do we find, it is to do with construction costs, although increased footprints have an impact on house build costs. As Table 3 shows, however, while nominal construction costs have risen for low-cost houses, real costs have been relatively consistent since the 1950s.
