You misunderstand my question.
If I emigrate as a retiree with residence visa (or whatever they call it) but keep US citizenship, does their welfare/health system consider me a resident entitled to services or just a “long-term visitor” with no services ?
IOW if I have resources and can pay my own way, they don’t want me as a retiree ?
The New Zealand Immigration site is really good and has all of the answers.
