I lived and worked there for 15 years as an immigrant. I can get you webpages….Have you looked at any webpages?
As far as I know, teachers and tradespeople are always needed. They need teachers willing to work in the smaller towns. With Christchurch being rebuilt, they have imported loads of trades people from Australia, but they tend to not relocate permanently.

It was hard to get a job at first. I was qualified to work for Qantas, and had an interview, but I didn’t have a work permit. The labour department only required them to write a letter, saying that despite the fact I wasn’t a New Zealander, I was the most qualified for the job and request a work permit for me. They didn’t. They hired a less qualified person. (who ended up not working out after the first three months after they spent loads of money sending her to Sydney for training.) I eventually found a manager willing to write the letter, but it wasn’t in my chosen field. I ended up making office administration/accounting my field, and left my dreams of being a travel babe behind.
I loved New Zealand. With the training I had in accounting and office admin I was never short of work, where ever I travelled there. I eventually worked with several businesses and learned production accounting and a few things about food product manufacturing and food technology. (my love of organic chemistry was born)
Getting your foot in the door can be challenging. The work permit process can be a real hurdle. Good luck. I’d go back in an instant, if my circumstances were different.
