So that's the first question. Then the second question is: what has happened to the register? Why is it not working? And, again, this is not a new issue. We talked about this in August; we talked about it again in February. Today, we discover, in response to questions, that the Government will make it mandatory from 27 April. Well, why are we only making something mandatory from basically the start of May when we've been having these problems since September? How hard is it to design a system that records people's testing status and design a system where that is checked every fortnight or at least sufficiently enough to assure ourselves that people are being tested? Where are the checks more generally? Because if we make the testing mandatory, New Zealanders rightly expect that the Government will follow that up.
