Leader of the Opposition Andrew Little said the figures showed there was a need for political parties to do more for the growing numbers living in rental properties.
"With more Kiwis locked out of owning their own home and stuck renting, it's time for Parliament to come together and solve the crisis," he said.
He's called on other parties to back Labour's KiwiBuild and Healthy Homes Bills that were before Parliament.
The Healthy Homes Guarantee, which called for all rentals to be warm, dry and healthy to live in, has passed its first reading and was due to be presented before the House early this year.
The KiwiBuild Policy called for 100,000 affordable homes to be built and is due for its first reading.
"Our policies are ready and about to be voted on by Parliament. All parties should back them. If we work together, we can fix the housing crisis," Little said.
