I'm from NZ.
Teachers in NZ have similar concerns to teachers in the UK - too much admin' work, too little non-contact time, too many kids to a classroom, difficulty with crowd control with mainstreaming of children with very high needs with neither the budget, the support, or the training in place to help them. And salaries. Although I think they got a reasonably significant increase recently.
Child poverty is an issue in NZ, particularly in Auckland. A big part of this is a disparity within Pasifika and Maori, who are disproportionately adversely affected, for a number of complex reasons. A bit like the Indigenous people of Australia.
Our current Government, Labour, has been working hard to address this, rather than blame it on those suffering, or ignoring it, but obviously this is not an issue that is going to be solved overnight. New Zealand, I think does tend to be a bit more progressive and liberal on a number of issues - say, Same Sex Marriage for example. To some that's a plus, to others, a minus.
New Zealand is very isolated. A lot of those who emigrate there, find this very difficult, in terms of friends and family, concerts and tours, arts and culture. It does have a relatively great work/life balance, particularly if you're outdoorsy, love the beach and the mountains. The cost of living is very high, and the housing stock is very different, and particularly older housing stock can lack insulation and be hard to keep warm. We don't have central heating as standard.
