Secondly, I just wonder about the Minister's view on contact tracing and whether we're getting value for money there, whether it's fit for purpose. A useful way to think about it is: is he pleased with the performance of contact tracing in the current outbreak? It seems to have taken about three weeks to get to a stage where everybody had been traced and tested in the South Island. The Minister might like to argue it's less, but that was with only 518 cases—and that in itself doesn't sound too bad by the time you add on 12 days to have your second test or third test—except the Prime Minister said it was necessary to keep the South Island at the alert level restrictions it was at because she "didn't know what was out there". So I just wonder how the Minister might reconcile that statement with the belief that contact tracing has been effective; and if he doesn't think it's effective, what can be done in this financial year to get contact tracing that is more effective? I notice digital contact tracing continues to play what appears to be, and the Minister can correct me if I'm wrong, a very minor role in the Government's contact tracing efforts. It seems to be mostly manual, and they had to hire a whole lot of people and train them up, mid-outbreak, in order to make that work as well as it has.
