So I want to make one final comment. I know this is really difficult, and I acknowledge that there's a lot not only for the select committee to get their heads around but also New Zealanders. But from a ratepayer perspective, I must be really frank about this: one of the overriding drivers for me was to think about the system change that is absolutely necessary to be able to assure ourselves that the most vulnerable or those on fixed incomes in our society don't miss out because of those who are well healed and say "we're going OK here, it's the other folk over there." We can't get inequity as an outcome of the system reform that we're trying to steward through, because everyone needs clean drinking water and affordable services. Everyone needs the assurance that we're going to do better for the environment than what we're doing now. I think our kids want us to absolutely make the kinds of decisions that will see liveable cities that look for natural solutions as well as smart design solutions, but actually that we put that long-term aspiration in front of our minds when we think about a way forward. And that's why I continue to believe, unless there's an alternative that's been put up by the Opposition, we should continue along this path, hard as it is.
