Try Nelson Aviation College. Situated at Motueka at the top of the South Island. It has 3 CPL theory courses per year, very professional. When I was there it had 4 R22s. Great place to train as it's a very busy uncontroled airfield and only a 10 min flight to Nelson for controled. Apart from Wanaka it would be the best place in NZ if you want mountain flying, only 5 minutes to Mt Cambell 5000 feet, Kahurangi national park is right on it's doorstep as well as Nelson Lakes national park. Great place to fly. Ring Ross Troughton, A cat Helicopter and B cat fixed wing. He fly's for Air New Zealand and is very experienced, he is great to fly with and easy to learn from.
