It allows for more frequent saliva testing, and I think that's a very welcome thing, but I just echo what Chris Bishop has said: every 72 hours in a Delta environment—arguably even that is not regular enough. There's certainly under-utilisation of saliva testing. It was interesting in question time today that the Prime Minister really gave some quite lively answers, actually. Uncharacteristically, she really let rip in a couple of instances. One of the things she said is we are no longer in an Alpha environment: we have Delta now. I think the Prime Minister is right to observe that. It's very true. But, you know, the funny thing is our testing is still Alpha. We still have nasopharyngeal testing, and sometimes only once a week or once every three days. We should be moving to much more frequent saliva testing and even rapid antigen testing. But three days is certainly what Air New Zealand will be using as a standard, and it's an improvement on once every week.
