I created this profile for Fenix A320, I don't have ATR 72 so cannot guarantee it will work with it or any other plane. The profile is for a free addon created by CoolGunS. Please download it from https://flightsim.to/file/69679/nznv-invercargill-airport-new-zealand-gsx-ready

I've never been to this airport and I could not find any photos showing how passengers exit and enter the terminal. I used one of the doors, please correct me if it's wrong.
