Rt Hon JACINDA ARDERN: I'm saying that it is not perfect—absolutely not. Because you go and get a test 72 hours before you depart, you still have a possibility of being infected in those 72 hours, or, indeed, in your transit to New Zealand. We've seen multiple situations where people have been infected with COVID-19 in often what are very long journeys back to New Zealand. So it is another layer. It is not a perfect layer. We do not rely on it. That is why we test people when they arrive as well, and we continue to test them throughout their duration here.
