ROBERT KITCHIN/STUFF PM Jacinda Ardern announced Auckland would go down one Covid-19 alert level on Sunday at 6am, while the rest of NZ would go back down to level 1. A flight attendant who tested positive for Covid-19 had been vaccinated against the virus days earlier. Meanwhile, it has emerged officials knew about the case at least seven hours before telling the public. Prime Minister Jacinda Ardern revealed on TVNZ’s Breakfast on Monday that the flight attendant had recently received the vaccine – while pointing out it takes around a fortnight for it to work. “Well this person actually had only just been vaccinated, so they were a priority for this exact reason, the issue being of course the vaccine takes a couple of weeks to work, so at this point it wasn’t quite doing its job, nor would we have expected it to, but it demonstrates that this person was indeed a priority for us.”
