I don’t know why they have Gisborne Airport. Napier where I live is a far busier airport with Air New Zealand Bombardier Dash 8s and ATR 72 600 serving it. ATRs from Napier go to Auckland and Christchurch with the Dash 8s going to Wellington. And also based at Napier is Skline Aviation which operates 3 Jets and 3 types of Beechcraft.
