Rt Hon JACINDA ARDERN: Of course, you'll see with the low rates there that our ability to extinguish that outbreak continues to exist. What we want to make sure, though, in the meantime is that we don't see that outbreak prolonged by contact—moving too quickly into levels that would create additional contacts. So there is a view that with our current rates of vaccination, we still have the ability to extinguish and then move into lower alert levels. But, of course, if you want the greatest certainty of all, it would be high vaccination and moving into the new traffic light system.
