I live in OZ, I import all of my film off ebay.
From UK, China, HK, Taiwan, Thailand, US.
Also do my own colour processing with minilab chems from vanbar.
Always some great deals to be had on ebay... 10x 120 roll of Provia 400X (fresh) was $39 AUD delivered etc.
You could mix up your own E6 first dev.. fixer from pool shop chem or supermarket chems if you cant get any photochemical suppliers in NZ, and your own colour developer from hair dye etc.
