Rt Hon JACINDA ARDERN: Well, I'm happy to speak to some of the variables. We have done some estimates, but the variables are so significant that it makes it difficult. We've done those estimates in order to establish how much resource would be required for our care in the community model. But just to give the member some context on a low assumption—where we would be if we were something like South Australia. In terms of their peak, you could reach something like 5,000 cases a day. On the high, it would be closer to, for instance, the state of New York, at over 30,000 cases. Keep in mind, of course, you'd expect at those levels a narrowing of your definition of close contacts. We have been very pragmatic and evidence based. In phase 3, if we reach high rates, the definition of close contact narrows to a household definition because that is the most common place that you're likely to see transmission. Those are the groups that you don't want then circulating because you're very likely to pass on COVID to others.
