My understanding was that actually for people in NZ they were better off than we were in the UK. Yes they had very strong border control so international travel is difficult/impossible, but once it was clear they had it under control the internal restrictions were fairly light. I remember seeing a photo of tens of thousands of people at a rugby game at the same time as fairly serious Covid restrictions in the UK.
I think he's asking the wrong question - if you ask me "am I willing to not leave my country for two years (but have little other restriction)" for 10-15 days of extra life, then yes that sounds fine. I like international travel but can live without it for a while.
I think half hearted Covid restrictions are the problem. The UK has to me the least forgivable Covid situation. We are an island with easily controllable borders (like Japan, NZ, Aus) but we never did. There is a lot of evidence of getting Covid under control and then being re-infected from abroad so it doesn't matter that we got it early - we could have kept it under much better control.
