as per 27/09's post, I would personally
recommend North Shore Aero Club
www.nsac.co.nz

+64 9 426 4273
They're based at dairy flat, about 25 mins north of central auckland. The fees are very competitive and they own the airfield. The fleet of robins is good, as are the instructors.
I think North Shore Aero club offers a lot more than other options around NZ, the attitude of all there is great with a focus on flight training, safety and having fun.
If you want any more info please PM me. I'm a member there and readily
recommend it to anyone looking for flight training in NZ
