Being a kiwi I can't really answer your question, but coincidentally there was a report on national radio here this morning about how people were traveling here on student visas to study, staying on with a job after graduation and getting residency that way. That maybe something worth looking and a good opportuninity to address the lack of college education at the same time. You'd need some reasonable savings to afford the education and living costs for up to 3 years.

If NZ educations costs are the same as Aus education costs, I'd estimate "reasonable savings" at about $100,000.

20k per year education, because it won't be subsidised by the government, 7.5k per year as minimal living costs, and that's really minimal.
