We, of course, have already promulgated a real increase in the standards that we expect of those who are using land and are causing harm to waterways. I heard the Hon Mr Bennett asking questions about that. In reality, what we inherited was a situation where twice as many rivers were degrading in New Zealand as were improving year by year, according to the macroinvertebrate index, which is probably the most accurate measure of aquatic health. So in advance of changes to the RMA, we thought it was necessary to make changes to cause those problems to be brought under control. And I'm happy to answer questions about that, because, in fact, that did happen during the year under annual review.
