Is that why the UK also has next to no Covid whereas in Germany it.....oh.....hang on.....
Germany is the real example for the UK to look at and go "well maybe we should have....."
What NZ doesn't have (and I claim no credit for this thought, I simply agree with [MENTION=3969]Billy the Fish[/MENTION] ) is a massive hub airport. Our biggest threat of a second wave doesn't come from thirty odd teenagers sat on Hove Lawns smoking dope, nor of people gradually letting their kids see their friends, or even protests in big cities. It comes when we reopen Heathrow to international transport on a large scale. Unless that is timed and quarantine and temperature testing in place and enforced, it'll all be back to the ICU before you can say Boeing 747.
NZ is isolated from that. Paris has the Eurostar and Air France connections, Belguim the Eurostar and flights to its ex colonies, Madrid was a hotspot in Spain. It's a very convincing argument and, as I said, it's not mine originally.
That said Jacinda Ardern was hugely impressive after the mosque killings, has managed to run a country on maternity leave, and seems to have called the slightly easier job she did have correctly. She's no Boris Johnson.
