When we came to the reform process—as a consequence of the Health and Disability System Review report that we published at the end of last year that followed a very thorough analysis of the system; extensive consultation with communities around New Zealand; and a very close, considered study of our health system—it's very clear that change was warranted. Change is needed. We're not getting the benefits that we need in our health system when it is disaggregated across 20 different legal entities. And it is no criticism of anybody in that system, at the leadership level or otherwise. In the end, people respond to the structure they're in and the environment that they are in, but the reality is technology has changed; the population is changing. Our health performance is revealing that we are simply not keeping up with health demand. And where people get health is changing as well. So we have to change the way we make health decisions. That's what the purpose of this is.
