Hon CHRIS HIPKINS: I think there are probably a variety of reasons. We made the decision to start collecting data when we got to the point where we wanted to assess what difference vaccination was making on the rate of positive cases that we were having coming into the country, and that included introducing the additional testing requirement. So we introduced the additional testing requirement so that we could do exactly what the member has just asked us to do, which is chart out exactly where in that sort of 14-day cycle we were picking up the majority of cases, because one of the issues is at day zero, at day three, and then at day 12, it's quite a big gap between the day three and the day 12, and so we wanted to see of those day 12s, could some of those be picked up earlier so that we can actually make those kind of informed decisions, both about the role vaccination might play, but also about the role a shortened MIQ might play in our future border settings.
