I think we have to understand that we are not in the same situation we were three years ago. Covid is not the scourge that it was. Some people will be affected badly if they get it, same as flu, Strep A and many other things. We can't keep treating Covid differently to everything else forever, just because of folk memory.
China thought, for some reason, they could keep zero Covid forever. They were incarcerating people in their homes, in department stores, in schools, if just one person tested positive. Even the Chinese people, who I believe are more amenable to the diktats of their government than we are, were getting fed up of that, when nearly every other country in the world is relying on vaccination.
About half a dozen countries have decided to test travellers from China. Which means a couple of hundred haven't. This country hasn't ruled it out, they have said they are not doing it right now but they are keeping an eye on things.
But here we are, talking about lockdowns and new variants. Its not proportionate. I think it is a function of the demographics of contributors to this forum, I agree maddyone. I hope you are having a fabulous time in New Zealand!!
