And I have a question that I'd like the Minister to address, and it actually relates to subsection (6)(b)(v), where it says that one of the factors that needs to be taken into account is the imposition of levels of fees, and then (v) says, "whether the estimated revenue to be received from the charges is sufficient to meet the costs and expenses of the clean vehicle discount scheme". Now, my question to the Minister is what happens to the revenue that is collected if the revenue collected is greater than that that is paid out by subsidies under this scheme? Will that money just go into the consolidated fund? Where does it go? What happens to it? Because the potential, I think, is that there will be significantly more revenue collected from hard-working New Zealanders who don't have choice and can't afford it, but will still have to be forced to pay this revenue-generating tax more than is paid out. So that's my question first off for the Minister.
