Rt Hon JACINDA ARDERN: As I tried to address in my original answer, originally we were using GPs and CBACs in a voucher system. That did not enable us to track whether or not all the staff we expected to be tested were tested. That is why we then moved to on-site testing. That began on 10 July and also on 16 July. It was clear then, once we were able to get numbers coming through from that—although it was never comprehensive because it didn't pick up anyone tested outside; keep in mind, if you're symptomatic, you would not be at work to therefore be tested—we identified that that coverage was not what we had expected. We were engaging with agencies around lifting those rates, including with MIQs. It's why we started mandating the rotation but also questioning with the Ministry of Health why those numbers weren't representative of the entirety of border staff. As I say, we did start to see numbers lift. From 31 July to 6 August, 211 border staff were tested, and from 7 August to 13 August they reported 571 were tested.
