I don't know the visa rules for an American obtaining PR (Permanent Residency) in New Zealand, but I have met a few Americans who have done it, so it must be possible.
For photography / outdoor living, Queenstown (or nearby) is outstanding ... not sure where you're from in the US, but a rough equivalent would be Lake Tahoe.
July is good for winter sports, November is better for the start of the excellent (and busy) summer season.
In terms f jobs, I don't know and don't wish to speculate. But despite NZ's relative decline over the last generation or two, it is still a much better-off country than most in the world.
Wellington is a great city too ... rough US equivalent could be Portland Oregon.
