SIMEON BROWN (National—Pakuranga): Thank you, Madam Chair, for the opportunity to take a call on the second clause in this bill, and the question I've got of the Minister, in relation to the commencement clause—it says, I think, that it comes into force the day after the date of Royal assent. However, in clause 4, the actual road-user charge (RUC) reductions don't become available until 21 April. I'd like to ask the Minister to clarify why there is a difference in those two dates, and why the Minister is not also making the RUC reductions come into force and available to New Zealanders—which is the intent of this piece of legislation—at a much sooner date, such as the day after the date of Royal assent. I have a tabled amendment on the Table which will address this issue in clause 4, but it is, of course, also relevant to clause 2, which deals with the date of commencement.
