Career and Jobs in New Zealand

One of my closest friends is moving to New Zealand. He is asking me to come with him (in 8 months). Since NZ has all the bits I love, mountains for hiking, beaches for surf, and a chill population, it started to draw me.

Has anyone considered/has moved to New Zealand as a software eng? Focusing on the three big cities: Wellington, Auckland, Christchurch.

What did you like/dislike about it? Would you do it again? How is the tech sector there like - career, salary, and recognition?

To put it blunt, would it be a career set back to move from a known city (my case: Toronto) to NZ?
