The government is planning to ditch the Resource Management Act - promising a faster and more simple way to manage the built and natural environment.
Two new bills replacing the RMA should become law next year, with the new system expected to take about a decade to bed-in.
A third bill focussed on climate, will set out how managed retreat would work and who would pay for it, but that may not be passed before next year's election.
The Environment Minister David Parker says the changes will free-up land and resources for more housing, and save developers, infrastructure providers and businesses hundreds of millions of dollars a year.
