Rt Hon JACINDA ARDERN (Prime Minister): Yes, and yes. It is essential that we have confidence that there's no undetected transmission in our community. This is true for the South Island, as it is for Auckland, as it is for any other part of the country. There is just no margin of error with Delta—a lesson many jurisdictions have, unfortunately, learnt the hard way. I've repeatedly said that level 3 is a watch and wait level—it's a crucial insurance policy. If there's something we've missed despite our high levels of testing and waste-water sampling, we can surround it, quickly contain it, and isolate it, and I would rather be in a level 3 environment to discover that than a level 2 environment, which would be a major setback.
