Rt Hon JACINDA ARDERN: A good question from the member. One of the things that we're always looking out for, if we for instance ever have a case—as we did in the August outbreak—that comes up through our community testing stations that we have not proactively asked to be tested and that we cannot immediately link, that is cause for concern. That means that we have to find time and the ability to epidemiologically link how they came to be infected. If we can't do that, that is a sign of community outbreak. So those are some of the things that make the wider surveillance testing across Auckland really important.
