If you like the sound of NZ but don't want to commit to such a big move, come check out British Columbia. We're like NZ lite. :)
Having spent approx half my working life in (Wellington/Vancouver) I'd say Vancouver would be a more natural fit for our US cousins.
However that said you can't beat NZ for internal travel, day trips, adventure tourism. Its basically a compact version of British Columbia.
It also spans roughly the same range of climates - Dunedin where I live is Seattle/VancouverBC sort of climate (and the southern West Coast is very Olympic Peninsular subtropical rain forest). On the other hand Auckland/Northland is Californiaish but with more tropical moisture because we're an island and not a continent
