Kia ora koutou.
I have Qantas Gold status (thanks to a status extension deal) but lost my Air NZ Gold last month due to not being able to fly due to pandemic restrictions and pretty restrictive extensions from Air NZ.
I was wondering if anyone knows how to book a domestic flight (WLG-TRG) within NZ (on Air NZ) but with a QF codeshare booking code. This can be done when connecting to a QF international flight but I can't seem to find a way to do this for a single domestic flight.
The reason I ask is this would allow me to utilise my Qantas gold status within NZ (lounge access etc). Any help would be much appreciated. I wondered whether travel agents or flight aggregators might be an option.
