Finally, I want to deal with the issue of the COVID-19 Public Health Response (Alert Level Requirements) Order (No 12). This is the one that was presented on 23 September that moved Auckland and the Upper Hauraki to alert level 3, and kept New Zealand at alert level 2. This is in relation to the rules regarding the obligation to carry evidence of a COVID-19 test. So the existing obligation at the time was to carry evidence for a COVID-19 test taken no more than seven days before a journey. It then introduced an obligation of no more than 72 hours before a person's journey. The point I want to make is that with Delta, 72 hours is actually, arguably, still too long a time—that for the imposition of these requirements on people, we really should be moving to rapid antigen testing, as I think David Seymour said.
