David Seymour: Why is the Government still requiring international arrivals whose final destination is Auckland to go through any level of managed isolation and quarantine if they're fully vaccinated and have tested negative for COVID-19, when over 700 people who've tested positive for COVID are allowed to self-isolate in Auckland; or are the University of Otago's Nick Wilson and Michael Baker wrong when they say, "If you're at the supermarket in Auckland, a fully vaccinated person randomly teleported from Canada is less likely to infect you than an average resident Aucklander in the aisles."?
