The Labour Party says if elected, it would build 10,000 affordable homes in Canterbury in the next four years.
Housing spokesperson Phil Twyford announced the policy in Christchurch on Friday, saying the Government's current stance that a broken market will fix itself is not good enough.
The Canterbury earthquakes in 2011 destroyed over 11,000 homes. But Mr Twyford says in three-and-a-half years, only 1000 of the 12,000 to 15,000 homes required to fix the city's housing crisis have been built.
Mr Twyford said a Labour government would build the 10,000 homes. Jobs would be contracted out to private companies and the homes then sold to first-time buyers.
Each home would be sold for between $350,000 and $400,000.
Housing Minister Nick Smith disputed Labour's figures as incorrect on Friday, saying his show that 3500 homes have been built, 50,000 repaired and a large number have received emergency modifications.
The general election is on 20 September.
