As someone who just came back to NZ after 8 years away, this will be the best advice i can give you: PACK A TON OF FILM! I would go as far as saying that if you dont need to, you should wait till you get home to develop them, otherwise your travelling budget will be severly impacted.
To give you an idea, imagelab in auckland charge NZD30 to develop a roll of 35mm exposures (x36 4R prints). A roll of Tri-X (36 exp) costs about NZD13 i think. I dont shoot MF, but i would think the prices would be crazier!
