The New Zealand agricultural industry seems to run mainly on tourists (young rich kids on work-and-travel visa) and it's working just fine.

Yeah, I'm pretty sure most folks doing "real" work don't care who you are as long as you show up on time, get shit done, and aren't (the wrong kind of) an asshole. And the last part's negotiable.
