Rt Hon JACINDA ARDERN: Of course, we did agree as a Cabinet that in our testing strategy there would be testing of asymptomatic border workers. That had started with pop-ups at the airport in July on multiple occasions, but we have been very open about the fact that it wasn't as comprehensive or scaled up as quickly as Cabinet had desired. That is why, of course, we have put in place additional supports in the Ministry of Health to ensure the roll-out of that. We are now in our second sweep of border workers at the ports, at the airport, and in our managed isolation facilities, and it is important to note that alongside those sweeps we as yet have not identified the source of the resurgence we've seen in Auckland.
