I've seen more games banned in AU than NZ. And the odd game that was banned here I ordered from the US. I think the only people it stops from getting the game is ... well very few people. Anyone with access to the internet and/or friends can get hold of them.

In today's age a credit card + internet = anything you can afford! Oh... I think my courier just arrived, its a large crate from Taiwan 8o

EDIT: Just did a quick check, it has not yet been banned in NZ. Its more than likely shipping in NZ.
