It is hard to say it will not work when they’ve had less deaths *and* less lockdown than we have.
This is about the future though, when they aren't quite literally isolating as an entire country from the outside world.
It can work if they eliminate it and then have their population fully vaxed before opening their borders (even to fully vaxed people), but their roll out has been a struggle and as I have a vested interest in the place I like to keep track and it's still imo nowhere near what it should be for a country of their relative wealth, population size and healthcare ability to be able to roll it out.
This is what I mean. We're 18 months in, and we're eight months into the vaccines being available. Even if they'd started fully in April time, they could have had their population fully done now (and perhaps would have faced less hesitancy too?)
That's my only issue. That they shouldn't be going into a snap week-long lockdown for one case at this stage, given they've had so much time to get the roll out done. And had they got it done, they wouldn't have needed to.
I'm a big fan of the NZ PM, she's had some awful stuff to deal with and each time done it very well. But that's just how I see that situation.
