In terms of sustainable financing and the challenge that we're facing—and again, I raised this with the select committee when I sat in front of them to outline the reason and the proposition for reform during the Estimates—it is not one singular ambition that the Government is trying to ensure that it meets. If we look across a broad range of objectives of the Government in the three waters reform programme, which I spoke to at select committee, it is about sustainable financing, it is about—through scale and aggregation, but that's not the only benefit: it's about ensuring that there is ultimately a model that ensures affordability for ratepayers. It's about ensuring that in terms of both health and environmental standards, the looming costs by meeting a burning platform of higher standards can be met in a sustainable way. It's about ensuring that the Crown is able to uphold its Treaty of Waitangi obligations, because substantially when we think about the whole-of-cycle system and we think about the way in which Treaty of Waitangi settlements have a number of provisions which touch on the natural resource area in relation to water. Those are all the elements that are featured within the system reform that we're promoting.
