Rt Hon JACINDA ARDERN: The same criteria that we've used all the way through: taking a very close look at whether or not we have good containment, whether or not we have unlinked cases that suggest we have a wider outbreak that still may not yet have been manifest, and our ability to safely move through the alert levels. One thing I would draw a distinction between: we are not in the same position as Australia who, for instance, are easing restrictions based on vaccines. We do still have an outbreak here in Auckland that means there is not widespread undetected community transmission, and that has enabled us to ease restrictions, but we'll continue to focus on doing so safely.
