Here's a question for the Minister. He can't answer it now, but we'll get to it in a committee, and if it's not fixed in the committee, we'll be bringing forward some Supplementary Order Papers. Why is there a difference between somebody that has a fixed, self-contained unit—he said "has to be plumbed in"—and a responsible New Zealander with a campervan, who might be mum and dad or your grandparents, who has a portable one and they are responsible? It's not a bucket with a lid or some of the other things we hear about., because what the Minister has decided to do is say to the vast majority of New Zealanders who like to go camping in their vehicles and don't have plumbed-in toilets that they can't get certified and, therefore, they will be restricted. Actually, every four years, you're going to have to get your vehicle certified, whereas for many of these vehicles, every year, when they get their warrant of fitness, they make sure that it is fit to be on the road.
