Rt Hon JACINDA ARDERN: Of course, to the best of our ability, we try and reduce down risk, but we always make an assumption that every single traveller coming into New Zealand has COVID-19. That's the assumption that we work off. I now recall the additional piece of advice was that one cannot make an assumption that a 72-hour pre-departure test immediately eliminates the possibility that someone will have COVID-19. It doesn't, and so that is why we do day-zero testing as well. It's also why we have testing across the course of someone being in managed isolation, and, interestingly, what the advice also contains, to Ministers from 9 July, is the reported level of incidence in New South Wales of late onset and then wide infection. I recall now the additional thing I wanted to share with the member: we also, of course, had a health declaration. So everyone who was travelling also had to declare that they had not been at a place of interest or in contact with someone who had COVID, and that was at a time when in New South Wales, as I say, 38 cases were being reported a day. So that was an additional declaration that had to be made by everyone who was coming in on those red flights.
