JamesL: Apologies if this has already been discussed but couldn't find anything when searching, with my SGS2 I had the ability to set the system language to English (New Zealand) however there doesn't seem to be this on the Nexus
Is this possible or not?
Doesn't look like it. I set mine (or it may have defaulted) to English UK under Settings > Language and Input. In Voice Search settings, it is possible to set it to English NZ, which I assume helps it with recognising the NZ accent.
