The RMA has been the foundation of our environmental legislation for the last 30 years, and its purpose in sections 5, 6, 7, and 8, in Part 2 of the Act—that whole concept of sustainable management, the matters of national importance such as the preservation and protection of the natural character of the coast, the margins of rivers, significant indigenous vegetation and habitats—has been hotly debated and contested in front of councils and the courts. The drafting of the purpose statement of this new legislation needs to be done with enormous care and skill, and I really hope that it's a focus of submissions on the exposure draft which the Environment Committee will be considering.
