More online information about New Zealand can be found on the government's website: http://newzealand.govt.nz/.
It's got lots of information and links to related websites; just about what you'd hope for a government website should have. Gather as much information as you can and consider all parameters that matters to you so you could choose wisely whether you'd survive here or not.
It's also a good channel for which to learn about the culture as to how they do things here in NZ. Similarly, you should also check out websites like this for that particular country you're interested in.
Being new to a country and community, among the things you'd hate to have are gotchas or surprises all because you didn't do much of the necessary research up front.
