The final point that the member made is that they might come back for more and say they need more in the future. Well, that's possible, but every additional amount that they take from the river, assuming that the current minimum flow regime is proper—and we're in no position to judge that here—comes at the cost of someone else who wants that water. There is a feeling within the Waikato region that, although they want to help Auckland, they don't want to go so far as to prejudice either the river or their own commercial or municipal interests long term. I think it's very interesting that this conversation has opened up the reality that already the water that they take from the Waikato River includes treated waste water from the Hamilton and other towns that lie along the banks of the Waikato River. Therefore, effectively, the water that Auckland is taking at the bottom of the river and treating, once it's pumped to Auckland, includes treated waste water.
