BB is quite right you cannot access the NZ P lounge at AKL with a *G card, except on some occasions or for some reasons they let you in.

But to be honest you did not miss much. It is smaller and more intimate than the J/*G lounge but the food, drink chairs etc etc are all identical. It is mainly just less crowded for those who like to avoid the crowds.

Also the cabin director tends to mill around and chat to people longer in that P lounge.
