have only realy had dealings with Waikato Aeroclub in Hamilton. However some that are also recomended are BOB Flight training in Tauranga, Nelson Aero club, Don't know much about Quantum but not heard anything bad either, can't remenber the name but the mob in Dunedin and wakitipu aero club. There are also many more out there it all boils down to what part of the country you want to base yourself
