I lived in NZ more than 10 years since my high school. IT jobs is rare. For example, in whatever years, say US has 1000 IT jobs, Canada would have 100, Australia would have 10 and NZ could only have 1 or less. This is the ratio.
Luckly both my wife and I had good IT jobs there, but earning are limited compare US EE engineers. So 4 years ago, we migrated to USA to seak further career advancement and despite the harsh economic condition in USA now, we thought it was still much better than NZ in terms of jobs. We earn about 3 to 4 times than in NZ by doing similar job.
Education system is good, especially the universities. Life is very peaceful. And country is very beautiful (just go and watch the movie "Lord of Ring", they are real NZ beauty).
