Ooo, Nelson food events? Specific to regions of Mexico? Sign me up!
We may actually spend a few months in Mexico before we make the big move to NZ, so at least we will be stuffed with all the goodies beforehand...(although it will probably just make the hankering far worse lol)
During our research trip almost 10 years ago, we also objected mainly to the cheese when we were able to find a burrito in Christchurch (having rejected the first Auckland and Wellington offerings we found, based on price point, heh). Yes, the cheese may be "tasty" or "very tasty," but it sure isn't Monterey Jack. Has anyone been able to find a jack-like cheese?
Back then, a Mexican ex-pat pointed us to an international food court in Auckland that was actually pretty good. They did the rice in these cute little pyramids...wish I could remember the name. They complained about not being able to get tomatillos and such due to import protocols. If there's no protocol, you're SOL...
I wonder how much has changed in the meantime? I'm guessing not a ton :-) Glad to hear that dried pintos, fresh chiles and masa can be found, at least. It's just not the same without cheeeeese!!
