Rt Hon JACINDA ARDERN: My understanding of this case, unlike the Northland case, where we had really good use of the COVID Tracer App by the individual in question—in part, I put that down to the extraordinary efforts that go in while people are at managed isolation and quarantine to encourage the use of the app. My understanding for these cases that we've been dealing with, certainly those that we reported yesterday, they did not use QR scanning. That does not stop, of course, the Ministry of Health from sending out notices in other forms to those who may visit different places. I would need to check what they did in that regard, but I do know these cases did not scan.
