I've always wanted to visit New Zealand. Recently my significant other and I were looking into WWOOF (willing workers on organic farms) It's a work exchange program for room and board, I was wondering if you've heard of it. We know someone here who did it and had a great time. Welcome to BYC!
Yes I have heard of that type of thing happening here in NZ, and I may know of just the person you need to ask regarding the info you are needing. He most likely will be able to point you in the right direction if you email him. I have PMd you his info.
