Hon DAVID PARKER (Minister for the Environment): Thank you for that contribution. The member does raise a fair point. The background to this issue is that, quite sadly, New Zealand's wetlands have largely been lost, even including wetlands that are within national parks. New Zealand lost 90 percent of our wetlands quite a while ago. That's sad, but even sadder still is that in the last decade, of the remaining 10 percent, we lost about a 20th. So we as a Government decided that we needed to introduce strict rules to stop the further loss of wetlands, and our intention was to stop the major loss around agricultural areas, which is probably where most of the loss has been. We wanted to make it harder to lose wetlands to subdivisional activities, and we came up with a rule that, as the member has quite rightly said, included a prohibited activity from nixing other wetlands generally.
