The "solution" that wasn't

In 2013, National introduced its "solution" to housing unaffordability. Its "Special Housing Areas" were basicly a developer's charter, with fast-tracked resource consents and lax oversight. The aim, as stated in the bill's purpose clause, was to "enhance housing affordability by facilitating an increase in land and housing supply in certain regions or districts". Higher supply (via lower standards) was supposed to lead to lower prices. Instead, it raised them:

The previous government's solution to the housing crisis in Auckland actually made homes less affordable, research has found.

Special Housing Areas (SHAs) were created in 2013 and touted as "crucial" in "enabling young Kiwi families to get into their own home".

Developers were offered fast-tracked consents on the proviso a portion of the development would be "affordable".

But the creation of Auckland's SHAs have now been found to have pushed up prices by 5 per cent within the area.

[...]

"The SHA programme simply allowed developers to offer new homes with an additional attribute (a shorter delivery time), which allowed developers to set higher prices," the researchers said.

So, National lowered consent standards, and their greedy developer mates made out like bandits. Why am I not surprised?

The market is not going to provide affordable housing, because there's just no profit in it for them (or rather, less profit than building palazzos for foreign immigrants). The only way it is going to happen is if the government builds those houses for us (and enough of them to crash the market). The current government, at least, is taking the first few timid steps towards this.
