I am in no doubt that the flying training and licence you end up with at the end of your time at Massey is of quality comparable to any other flight training establishment.
The big problem that I see with Massey is the time it takes, you can do a full time course to CPL / IR in approx 12-14 months. The extra time at Massey is, in my opinion' a total waste of time. The degree is so aviation specific it won't serve any useful purpose in the real world. At this stage NO airline in this part of the world requires a degree to work for them.
My advice, pick one of the 'other' flight training establishments from:
Become a Pilot
Use the time and money you save by not going to Massey to build experience in GA.
