Hon CHRIS HIPKINS: One of the most important things about our alert level system is that the public of New Zealand need to understand it, so they need to understand what is expected of them at each alert level. So we've now had plenty of time for New Zealanders to get used to what's required of them at level 2, level 3, level 4, and even at level 1. We have made refinements. I would reject the notion that we haven't continued to refine the system. For example, the changing policy around the use of masks is one of the things that we have put in place. We didn't have QR codes compulsory early on, and we have now got compulsory display of QR codes. So we continue to refine the system, but what we don't want to do is create a situation where people, on a daily basis, when they get out of bed in the morning, don't know what they're expected to do.
