Well, this is all about continuous improvement and actually making sure our border response is as good as it can be. It's been good—I don't deny that. It's been good. We are COVID free—that's fantastic, but the question is can it be better and can it be great, as Christopher Luxon says, and of course it can be better and of course it can be great. One way to make it great would be to roll out saliva testing. One way to make it great would have been to make the border register compulsory six months ago, and that's what we're talking about here. So we agree with making the border register compulsory, we just don't understand why it didn't happen many months ago.
