I used to live in nz with dp and ds.
Personally I didn't like it. All jobs seem to be located in Auckland with a few in Christchurch. Properties are both expensive and hard to find because of that.
Houses do not have central heating or insulation and a lot resemble little sheds.
Nz has high levels of teen suicide, poverty, homelessness, domestic and drug abuse and racism too. I found kiwis very welcoming to my face but never invite outsiders to events, tea etc. (Generally they don't like
Immigrants)
If you get into trouble financially you will not be able to get any help ( such as benefits) from the government as a non citizen.
Dp is Aussie so it was easier to move there as a family. There are also problems with contaminated water ( cow 💩 leaking and draining into rivers) and air pollution. Groceries are expensive and also bills and day to day living. It's also as wet as Ireland ( I've lived there too) and it's all rugby, rugby, rugby.
If you're into extreme sports the safety record is also bad with lots of accidents happening.
With ds, I found nz schools to be behind what he had learned in Britain.
It has beautiful scenery but not somewhere id want to live permanently.
