Let's talk a little bit more about the case investigation, because this has been an object raised by the Opposition. Case investigations are dynamic situations. They are done under high pressure, and I want to commend the work of the Auckland Regional Public Health Service and the national contact tracing staff for their contributions to this. What we require of our case investigations is that they work through an ordered set of hypotheses about how cases might have arisen. Of course, one of these started with the investigation into the LSG Sky Chefs workplace. As I said before, it is not enough just to suggest that because this workplace is at the airport, it is linked to the border. We instead need to find a plausible link between our case and an international traveller with COVID or a suspected international traveller with COVID. Let's remember: this is a workplace where there is routine testing.
