Hon SCOTT SIMPSON (National—Coromandel): Thank you, Madam Chair. It's good to, again, pick up on the conversations that were commenced towards the end of the sitting day yesterday. We're still on Part 1 of this Land Transport (Clean Vehicles) Amendment Bill. I've got a couple of questions relating to the detail of the legislation proposed in the Minister's name. This is a piece of legislation that's actually quite complicated in terms of its implementation. So if we go to—the area related to category 1 light vehicles in proposed new section 178, "Category 1 light vehicle importer may bank overachievement of carbon dioxide emissions" and then go to proposed new section 179, "Category 1 light vehicle importer may defer obligation" in both those sections there's a reasonably prescriptive and, some would say, complicated process by which both those objectives can be achieved.
