Hon CHRIS HIPKINS (Minister of Health): I think the member, perhaps, based on the previous discussion we had, might be misusing the word "compulsory". Actually, the vast majority of people do have tests on day three, and there are a significant number of cases—and there have been cases of those ones and twos that we're getting in recent days—where people have tested negative on day three and positive on day 12, which highlights the importance of the day 12 test, because we are picking up people who—if we just went on a day three test and then said, "You're still not showing symptoms. You can leave on day 14.", we wouldn't be picking up some of those positive cases. In some cases, they've been asymptomatic for the entirety of their stay, tested negative on day three and positive on day 12, and if we did not do that testing on day 12, we wouldn't pick that up. I think that that is very, very important.
