The second challenge we have is why are NZTA or the transport authority not the certifiers of this legislation rather than the plumbers and gasfitters, because what I'm trying to understand is how the plumbers and gasfitters board will have the ability and scope. They're going to have to set up a database or get access to someone else's—and there'll be privacy issues there—and then they're going to have to set up the regime and either find people to certify or, I don't know, maybe get plumbers to certify. I hope it's not the plumbers that will be certifying because, actually we need them building the houses that the Government's promised and that aren't being built but also, putting that aside, it's just, actually, factually not their job.
