I met a New Zealand network security specialist in Santa Monica recently. He and his mate moved here. When the general is calling forward the reserves, the reservist would do well to take heed of the front line that's coming toward them.
It's this vacuum and the growing tech needs that allows for these programs to happen, or for somebody to get a 5 year work visa on work experience alone.
Honestly I can't really see why I should go to New Zeeland even if they had a great jobmarket: why relocate half-way around the world to a country that as far as I know has no interesting tech companies.
If that's truly what's holding you back, I gather that New Zealand might not be the place for you. I have been told, however, that NZ has other fine qualities having little to do with tech. For instance, the fact that it's half-way around the world, and they talk like those musicians on that HBO show, might be reason enough for me personally.
