Can NZ produce enough food for its population? If so, that definitely seems like the right place to be in case of the apocalypse. Beautiful land, gorgeous ocean, intelligent populace, and far, far away from everyone else.
Also, there’s the Hokitika Wildfoods Festival in NZ (https://en.m.wikipedia.org/wiki/Hokitika_Wildfoods_Festival), where everyone dresses up in costumes and voluntarily eats foods that one might resort to during an apocalypse. Highly recommended.
I've watched quite a few wheat fields I grew up near become dairy pasture.
