I am a Koru and Silver member. If a family members flies domestic on a boarding pass under my name, normally this will be fine as there is no ID checking and the whole system uses kioks.

Will a family member also be able to enter the Koru lounge safely with a boarding pass under my name? They are the same gender. I am wondering if any other details might come up to the person at the entrance, such as age, which could give it away?

Edit: I am talking about a family member using a one off flight I don't need. A lot of AIRNZ passengers do this! I am not trying to 'hack' the system.
