Rt Hon JACINDA ARDERN: As I identified yesterday, we've had a first sweep of staff that has included both those that you would consider at higher risk, because, roughly speaking—280 or so agency staff just at Auckland Airport alone would be considered higher risk. There are then some that are further back that we would still want to be part of ongoing surveillance. They were part of our two weeks of sweeping through. We've started that again. We expect that will happen over the next fortnight again, and then, from there, we'll have a regime that means those who are more frequently interfacing, potentially, with at-risk individuals will be tested more frequently than those who are not considered at risk but we'd still want to be part of asymptomatic surveillance testing.
