My best friend lives in Auckland, so we talk most days on WhatsApp about what's happening there. I'm in Jersey, and she used to live here so she knows the island too.
We locked down in March and closed our borders like NZ, Aus, IOM and Guernsey (and others). Unlike the others, we opened our borders (carefully!) again in July, but with testing at the border. I will admit I was sceptical it would work, but to be honest it seems to be the best middle ground.
No, we're not Covid-free any longer (we were). But we're constantly on an average of about 15 'active' cases a day, and have been since the borders opened. No community transmission or outbreaks - all the cases have been identified at the border, or through contact tracing of those cases (our test and trace works well). Schools are all open as normal.
So we've got some freedom to come and go now, life is relatively normal, and we've been able to rescue some of the precious tourism which helps drive our local economy. But numbers travelling are low now the summer's over - mostly locals, but everyone is aware of the risk of bringing it back to the island from the UK now. (The UK used to be all green, but now it's all split up into green, amber and red zones, and all are treated differently at the border).
My friend in NZ thinks the way we're doing it is the right way to go in the longer term while we're waiting for a vaccine. She's worried because of the damage a lack of tourism is doing to the NZ economy. Covid is here to stay, and until there's a vaccine (our MOH seems to think a vaccine of sorts will be here by the spring) and we've got enough advanced orders in to vaccinate the whole island when it's released - that's only 106,000 though, so obviously not the number issues the UK has for vaccines. We've also got enough flu vaccines to give a free one to everyone who should have one anyway, plus everyone over the age of 50. For the first time ever, I'll be having one!
But it does seem to be that the things that make us able to live relatively normally over here are all related to firstly shutting our borders in March, and then testing everyone when we opened them. It's not perfect, and it's never going to lead to zero Covid cases, but we seem to have proven it works 'well enough' to prevent a second build-up of infections such as the UK is seeing now. Guernsey have been much more conservative, more or less still 'closed', and from what a previous poster said, the IOM seems to have chosen that route too.
There's no 'right' way to do it, but I think Jersey's made a pretty good job of balancing everything and still keeping things under control. I feel very safe going about my day as normal. I used to think we should have gone 'full New Zealand', but now I don't think it's the answer to try and lock yourself away until there's a vaccine. But then, we're a small island, not an entire country. Maybe that's where the difference lies in balancing the economics?
