The COVID-19 pandemic

I'm actually not sure of that, aside from by closing the border. Like, countries that suppressed Delta was already a small list. Who do you think is open and has actually controlled Omicron?

I'm not convinced that anything less than a NZ-style border closure (which surely could not work here) would have kept Omicron out. And even that may not end up working longer term in NZ. It's pretty hard to implement a successful Zero COVID strategy.
