The prefatory point here that's very important is that we have an extremely party disciplined system. The whipping in New Zealand is extensive and vast—some would say too vast—but we really enforce party discipline. You ally with that the fact that we have very large executives drawn from quite small legislatures. Half the Labour Party caucus is a member of the executive. It's about 50:50, and it's no different across Governments—I'm not making a party political point. I'm saying that's the constitutional nature of it, and we have list MPs.
