Rt Hon JACINDA ARDERN: Because as we've always said, our outbreak has been and continues to be different than those outbreaks we've seen in Australia, where they were using vaccine to exit their outbreak. What we wanted to do was maintain the ability to continue to assess the progress of the outbreak alongside our vaccination, so not necessarily say that everything would be contingent on single vaccination rates but to continue to assess the containment of the outbreak. That is why we made the decision, of course, as you know, in level 3 to have a step 1 change that allows people to gather outdoors.
