Hon CHRIS HIPKINS (Minister of Health): Just very briefly picking up where David Seymour began, I think he misunderstands the escalation process around alert levels. We moved up the alert levels at the beginning, for a defined period of time, in order to scope the extent of the problem—how far had the virus spread, how many people were involved. The extension was then for a full infection cycle, which is two weeks. Our decisions here have been made based on science. The continuation of that period is because we have not yet found the absolute outer limit of the cluster. We're still seeing new cases in the cluster, but the recent ones have all been linked to the cluster, which does give us confidence that we're getting on top of things.
