I'm pretty sure that the answer to the following question is "no" but I'm hoping for a knowledgeable response.
I've been poking around the web site of the New Zealand embassy in the US trying to find out if there is such a thing as permanent legal residency status in New Zealand. Since I can't find anything about it, I assume that there isn't.
Several countries grant permanent legal residency to non-citizens provided that they can demonstrate they won't be a burden to that country.
I obtained permanent legal resident status in Uruguay by:
o taking a physical exam to show I wouldn't burden the health care system,
o getting an Interpol background check done by the US FBI to show I wouldn't burden the criminal justice system,
o providing proof of retirement income to show that I wouldn't burden the social services system.
There were some other minor hoops to jump through, but surely you get the idea.
Nearest thing I've found is a visitor's permit that lets you stay in NZ 6 months a year. I can stay in Uruguay the rest of my life if I want to, no problem. I'm just not a citizen. No such possibility in New Zealand, right?
