I think the second thing I want to emphasise is around saliva testing. Remember, we called for this in the Northland outbreak two weeks ago. Here we are discussing it today. Clearly it works. I've got no question with that. Arguably, the sensitivity may be less: some of the enzymes in the mouth can degrade the virus; you get less viral load in saliva. It's actually quite tricky in the laboratory as well, and it doesn't do well with dilution. There's other issues actually getting it as well: you're not allowed to eat, chew, or smoke, for 30 minutes beforehand. So yes, I understand all of that, but what I heard from across the House today was that it's an infrastructure problem. Yes, we can't pool samples—I get that—but this is, sort of, news to us, where we're relatively happy to throw money around, and suddenly we're hearing an infrastructure hurdle which we hadn't heard before.
