"I know the enforcement of existing legislation has been seen as a major barrier in providing better rental properties for people."
Maori Party co-leader Marama Fox said while the party welcomed the changes, she questioned the delay in enforcing these new requirements and whether the proposal went far enough.
"A high proportion of whanau Maori live in rentals and we would have liked to see the proposed changes come in a lot sooner," she said.
"Do landlords really need one year to install smoke alarms and four years to insulate their properties?"
She said the Minister for Building and Housings had finally released the headline results from the trial warrant of fitness (WOF), carried out on Housing New Zealand (HNZ) properties last year.
"The WOF trial was initiated by the Maori Party because we wanted to know how healthy and safe HNZ homes are," she said. "It is of major concern that only 4 per cent of the HNZ homes trialled met the full requirements.
"We will continue to advocate for a warrant of fitness on all HNZ homes and private rentals. We will make sure the government does not become the biggest, 'slumlord'."
