Hon CHRIS HIPKINS (Minister for COVID-19 Response): I think it'd be fair to say it's not necessarily that the thinking has changed, but the thinking is changing and evolving, and it is an evolving situation that we're dealing with. I think that there are some things that we should put on the table and be up front about; the first of which is: do we think it's viable for a prolonged period of time to continue to restrict movement at the border to the, sort of, 4,500 rooms' worth of people in any given fortnight? I think the reality is it is not going to be viable to sustain that beyond the, sort of, immediate global response phase of COVID-19, which is obviously—the pandemic is still raging. So we are going to have to think about alternatives to that. Things like self-isolation are part of the question. Things like the elimination strategy itself and how the elimination strategy evolves, first of all in New Zealand that has a high rate of vaccination, which of course is what we're all pitching towards, but also in a world that will increasingly become more highly vaccinated over the next year, 18 months to two years. Now, we can look at some of the countries in the OECD and see high rates of vaccination there. Actually, they're not the ones that I worry about in terms of the spread of the virus. The virus is spreading and mutating in countries that have low vaccination rates. And actually, they are going to have quite a big impact on what happens at our border, those countries where the virus continues to spread, because what the epidemiologists and the virologists and all of the other scientists will tell us is that breakthrough infections—when it comes to vaccination—are more likely while the virus continues to spread rampantly. When we can turn that volume down globally, that is the point at which everybody becomes safer.
