Rt Hon JACINDA ARDERN: The Minister for COVID-19 Response could walk the member through the health order processes that are applied any time that we have to make an amendment to a COVID order, and that has happened from time to time because we have made decisions based in real time from what we were experiencing and seeing during an outbreak. As I explained, possibly in the House or possibly in a previous stand-up, some of the research that we're seeing out of Delta is only since June—it's not as extensive as some of the other variants. We are aware, of course, now that aerosol transmission is an issue with Delta and we've had to amend our alert level settings as a result of that, and we've seen that in our real-time experience. The public health advice that we received on variations of that nature to alert level 2 came through on the Sunday prior to announcements, and that is why the accompanied orders would be in sequence with that.
