networkn:
Have you checked out the library of those services NZ vs US provided? It's why I use the US libraries.
Netflix NZ has a number of shows not available on US Netflix. E.g. Stargate is available in NZ but in the US as apparently another streaming service has the rights to these shows in the US. It seems certain rights holders licence a whole lot of smaller countries (including NZ) to Netflix while cherry picking the US rights to Netflix competitors if they can make more money doing so. This puts NZ in the interesting situation where we could actually be better off not having Netflix's competitors come here...!
