I am curious how this will work long term, as we are nowhere near controlling COVID on a global scale and even well resourced countries in the West or very disciplined/authoritarian countries are struggling.
I see this a bit like psy-ops. Get everyone vaccinated as much as possible which probably going to slow down at around 80%. Then start reopening border and fuck those who didn't bother vaccinating. Otherwise remaining 20% is going to take years.
This won't happen. NZ keeping Covid out is down to good luck, not competence. On a long enough time scale NZ will face the same fate as those across the ditch.
