I completely understand that many New Zealanders and, indeed, members of this House have expressed concern that we don't know what is going to happen and that the Government can't tell people with perfect certainty what will happen. But I think that most people would agree that the Government has been very, very clear in communications, has given people the confidence to move into level 4 and then into level 3, and that as soon as we have the best information we are communicating that in a way. Of course, in a pandemic situation with a previously unknown disease, it would be impossible for us to provide absolute certainty to everyone about how it's going to play out. We have to make decisions based on the very best evidence of how many cases there are, our ability to contact trace, our ability to contain things.
