New Zealand's planning laws will be overhauled in the next term of parliament after Labour joined the opposition National party in pledging to repeal the Resource Management Act (RMA).
One of New Zealand's most controversial pieces of legislation, introduced in 1991, the RMA regulates land use for planning purposes and aims to promote sustainable development.
It is often held up by business as a handbrake to development.
On Friday, Prime Minister Jacinda Ardern said she would repeal the RMA and replace it with two new laws if she won the October 17 election.
A Natural and Built Environments Act and a Strategic Planning Act would come in the RMA's place, mirroring a working group's recommendations.
"Overly restrictive planning rules are one of the causes of high house prices," Ms Ardern said.
The Labour leader said the changes will "remove complexity and inconsistency, improve environmental outcomes, and reduce costs for all involved".
Environment Spokesman David Parker said climate adaption legislation would also follow.
Labour's move to repeal and replace the RMA has been National's long-held policy.
At the release of the working group's recommendations in July, National leader Judith Collins said Labour had "wasted three long years" writing the report "when it could have done what National has been saying in the first place".
"Investors, developers, workers and voters can't trust Labour and the Greens to deliver on repealing the job-killing RMA," she said.
