ANDREW BAYLY (National—Port Waikato): Thank you, Madam Chair, and I thank the member for her question. I'm just looking at someone in the gallery who was involved in the original drafting of the bill. I just want to acknowledge the original sponsor of the bill, Mr Mark Patterson, who introduced the bill. The bill as it was originally introduced, if I'm reasonably blunt about it, was pretty simplistic in the sense that it made clear that we should move to a 20-year horizon, but, effectively, it meant that would happen overnight—the day following the passing of the bill, effectively, or the signing of the Act. Obviously, when I was asked to take over the bill—because, of course, Mr Patterson left in the last Parliament. He asked me particularly to take over the bill. I accepted that on the basis that, obviously, the bill needed a lot more work, and I think Mr Patterson, to his credit, would acknowledge that. But he's put a bill in the House that has obviously got us to that point.
