My 2c worth.
Forget about doing your PPL on a 500. Do it in a 300 or, if you must a 22.
Then when you think you can fly, do a turbine rating.
I see from your other post that you got burnt for 3 large on some 500 time.
Mantra Numero Uno (repeat ad infinitum) NEVER PAY UPFRONT
And forget about sending emails and phoning up FTO's. Buy a plane ticket, a rucksack and some decent walking boots and visit all the operators on your short list unannounced. Seek out past and present students and pump them for information. Ignore fancy websites.
Don't think you can visit NZ and have a nice holiday and learn to fly at the same time. Too many distractions my friend. One or the other. Fly first then party.
Good luck.
