mainland air is a brilliant school that is held back by the dunedins lack of runways (only 1) however tieri (sp) is 1 minutes flight away off the northern end and thats a grass based GA field which helps a lot.
they are now shifting the PPL students to alexandra which is a great town with great weather and a cute lil airport, wanaka, queenstown, invercargill and dunedin all within 45 minutes flight.
can recommend NAC and mainland to anyone.
