The Government has asked the Productivity Commission to come up with a guide for councils on freeing up land for housing faster which they can use when special housing area legislation runs out in two years' time.
The commission -- which in a 2012 housing affordability study found land supply constraints were a key driver of high house prices -- has this week been asked by the Government to look at "potential improvements in local and regional authorities' land use regulation, planning and development systems".
The Government last year passed Special Housing Areas legislation to bypass council planning roadblocks and free up land for new subdivisions in a sharp response to the emerging housing shortage and rising prices, particularly in Auckland.
But Housing Minister Nick Smith said that legislation expired in about two years' time. He wanted councils to be in a position to continue to quickly release land for building after that.
"We've taken some short terms steps to try and unclog the pipe of housing supply but that does not answer the long term question as to how we move to best practice."
