The RMA has failed in a lot of ways. It really does cost too much. Processes under it take too long. They haven't protected the environment. We've had declining water quality, increasing climate changing emissions, and we haven't properly protected our highly productive soils. All of these are outcomes of the RMA, so it hasn't met its environmental purpose and, at the same time, it hasn't met its development purposes. Its development purposes include making enough land available so that people have got the opportunity to build houses or apartments or places where more people can live. As a consequence, in part, of failings of the RMA, land supply has been very constrained in New Zealand and, therefore, house prices have spiked. So implementation of the new system is essential to its success.
