I notice that Taumata Arowai is developing what we term three acceptable solutions relating to rural agricultural suppliers, roof water suppliers—and there are many, many thousands of roof water suppliers in New Zealand—and spring bore suppliers to create a pathway to compliance for small suppliers. I think that's a great challenge, and I'd be worried about the impact that might have on those small water suppliers, whether they be rural or urban, because there are many properties where they supply their own water as well. For those of you who have been fortunate enough to have a tank water supply, there comes a time when they smell quite bad and you've got to get out and clean the tank out. That's the signal that I've always used to keep my water supply clean. Done me no harm to date, but none the less that's the challenge we face, and that's the challenge that this organisation is going to face as it tries to implement the recommendations that have come from the select committee and as it tries to implement the recommendations contained in this bill.
