Hon CHRIS HIPKINS: No, I wouldn't characterise it that way. What I would say is that we've got increasing confidence in our track and trace—our test, track, and trace, if you like—system, which means that we can respond to cases of known origin and contain those without the need for alert level escalation. What we saw over the weekend, on Sunday in particular, was that we had a case where we did not know the origin of that case. We could not rule out that it would have come from community transmission that had previously been undetected, and we needed to assure ourselves and the public that there was not COVID-19 out there spreading through the community that had gone undetected. The significant wave of testing that we have had over the last 72 hours has given us that confidence.
