You know, actually all these NZ problems (and I extend my full sympathy to all newzealanders who are inconvenienced by them) might prove to be an indirect solution to Australian ones.
1. It is prohinited to sell an uncensored version in AU.
2. GoG is contractually obliged to provide the same game to AU and NZ, otherwise the distributors might sue them, since it messes up their (misfortunate in face of censorship) distribution strategy.
3. An unofficial patch is released.
Now CDPR has an aliby to support it! They can with all seriousness claim it was meant for NZ users, who deserve the uncensored game. The Australian powers cannot argue with that, and all Australians patching their games do nothing illegal, since distribution of uncesored material is illegal, not the possesion, right?
Let's hope for the sake of all of us, that the patch comes out ASAP. And while I agree that everyone misled by this last minute change of rules has the right to a refund, I applaud CDPR and GoG for their efforts to fulfill their promises as much as they can, even though they're being hindered at each step. They are actually risking a lot by providing all those options, and in my eyes that makes up for the lack of proper warnings, since if they pull this off, that info would be useless anyway.
Soon all version will be equal (and the proletariat will rule the World)!
Thinking more about this I think it has a lot of merit. There is no reason why CD Projekt can't release an official patch for the NZ version (both digital and retail) to re-instate cut content. There should be nothing contractually preventing them doing this from Namco Bandai's point of view since they surely don't dictate what DLC or patches can and can't add as content. NZ has been rated, I think, for the uncensored version, so they all deserve this patch no matter where they got the game from. Australian's can rejoice and thank their friendly neighbour for solving their problem too, but the patch is not "officially" for them to use.
Even if NZ was rated with the censored version (I think it's got a 16+ rating) I don't think the added content would be an issue there.
