I reckon loads will avoid getting tested in NZ so they don't end up in a quarantine facility.
Anders Tegnell reckons no country has ever successfully prevented an epidemic through closing borders, so it will be interesting to see how this plays out in the long run for NZ.
I find the idea of quarantine camps incredibly disturbing. Will be interesting to see how much authoritarianism the kiwis will put up with when the virus does eventually get into the general population. Even if the earliest vaccines are successful it will still be another 6 months minimum before any large scale inoculations.
