NZ Flying
For information I am vacationing in New Zealand later this year and so was looking at the requirements to use my PPL (FAA) there as well. It seems that you can only apply for a NZ PPL by passing their Biannual check at a recognised training school and then sending away for a licence which takes about two weeks and NZ$55. The CAA PPL carries an additional £16 payable top the CAA to let them release your details to the NZ CAA when they check up on you.
You need your CAA PPL in order to avoid doing the exams etc. over again. Otherwise to fly will need an instructor along. You can fly on your UK medicla whle it is valid too.
I have also been looking for flightschools and slef fly hire but it seems that there are not many that actually have websites - either that or there are not many full stop. When you get there and if you have time I would appreciate any recomendations from your experience.
