So the first one, if you look new section 167A(6)(a), set out in clause 5, "that the fees or charges are appropriate to sustain a scheme designed to increase consumer demand for zero- and low-emission vehicles and decrease consumer demand for high-emission vehicles:". So there we have the high-level objective of the scheme, which is pretty plain and pretty direct, and that is the purpose. It's not a kink of the scheme that we want to disincentivise the highest emission, most polluting vehicles; it is the purpose of it. And the purpose of it is that we incentivise those vehicles which are cleaner. Here I go back to New Zealand's performance in this area over the years, where we have built up one of the dirtiest fleets in the OECD, and it's been the lack of these provisions and regulations that most other countries have that have led us there.
