The first hint of a shortage of housing stock in Auckland goes back about five years, when building firms began saying there was a lack of skilled workers in the SuperCity. Many had skipped off to Christchurch to help with the post-quakes rebuild (there is now an oversupply of property there).
Then, three years ago, the housing market in Auckland showed solid signs of warming up. By the end of 2014 it had reached boiling point, and despite all the vocal concern about rapidly rising prices in the SuperCity, neither the government, nor the Reserve Bank, nor Auckland council did anything meaningful to turn down the heat.
Steve Hart's weekly property podcast:
One of the issues seems to be that the Reserve Bank and the Government appear unable to react with any speed to emerging trends. Rather than use common sense, they wait until there is a fully documented and peer-reviewed problem before dreaming up half-baked solutions that seem more to do with politics than people. And Land Information's attempt at measuring the sales of homes has delivered -- at best -- questionable data.
