Off list we have confirmed the only listed NZ applicable / available post code / zones in postcodezones is 00800 Pacific/Auckland.
To my understanding if a zone is not listed in postcodezones then it will not be available to make a match - and use.
It seems to me that a new reference needs to be added, however I am not sure which would be the relevant one for David for STB FreeView?
Can someone please clarify if this is relevant for David's problem?
