I live in New Zealand and have the same problem with the pricing of Canon gear. I find it hard to justify supporting my local camera shop when their price is 30% higher than on Amazon USA. Parrallel importers (with an office and back-up in Auckland) are a good 30% cheaper on some lenses.
I too believe that it is Canon NZ keeping the price artificially high for whatever reason. Maybe because they need higher margin to support the cost of having offices in a country with a much smaller market?
Whatever it is, I can buy a brand new 5Dmk2 on Amazon for less than a used one on internet auction site here in NZ. You do the math
I'd love to buy the next generation full frame 5D equivalent but I know it will be daylight robbery for the first 6 months of being available.
