The housing shortage in New Zealand has reached 60,000 and is growing by 40 houses a day, according to documents released to the Labour Party.
The figures are based on estimates by ANZ Bank and were included in a Treasury paper. ANZ estimated that the gap between supply and demand was 4000 houses each quarter.
Labour leader Andrew Little said the shortage reinforced the need for a major state-run building programme.
The Government confirmed in October it would play a greater role in the private housing sector and build tens of thousands of houses by redeveloping Housing New Zealand land.
Labour says that plan falls short of addressing the supply gap and does not guarantee affordable housing. Its own policy is to build 10,000 affordable houses a year for 10 years and sell them to first home buyers.
