The third part that the member, I think, is mainly referring to there—the fourth part being regulations relating to fencing and things, which I won't go into in detail—but the third part, which does take some time, is what communities, through their regional councils, want to do in their plans in order to achieve the requirements of the national policy statement on freshwater management. There are various ways that councils can address their issues. It's for them to decide how they're going to bring their river health and lake health up to the levels that are prescribed by the legislation, and they do that through plans. And then those plans, once they are in place, give a transition to improve things. We've said that we think the improvements back to swimmability and ecological health should take a generation. We actually haven't defined that; we've left that to councils to work out.
