What this bill does for me is that when I think back to these particular people that are contributing to our construction in this country—they are going over and beyond in order to train apprentices and do right by New Zealand and people and what this Government is attempting to do, which is to build houses and hospitals and schools—why should they have uncertainty? Why should they have uncertainty about a proportion of their payment, 10 percent, in fact? Therein lies the challenge for me—that we want these people with our infrastructure spend to gear up our workforce, to gear up their business, to help us build houses because it's in dire need in this country, yet they have all the uncertainty. That's the question that sits with me.
