I was asking @HuaweiMobileNZ on twitter about the update to Nougat for this phone - or at least the security patches (phones is currently on Nov 2016)
The rep said there will be no Andrid updates for P9. I asked a bit more, and they said not for P9+ either.
It's been released in lots of other markets, so not sure why they can't release in NZ? I knows they have to submit to the carriers, and this may be both VF NZ + Au before it could be released.
