Right back at ya Kiwi...
Good thing you are from NZ, at least you won't have to go through the immigration process. One of the biggest hurdles for any non Kiwi getting on with Air NZ.
As far as the FAA to CAA conversion. I'm not going to be much help there. I think because of your current job flying RJ's (100hrs SIC or 500hours PIC in air transport ops) you should be able to convert straight over to the ATPL with a couple of tests and your sim check at Air NZ. The tests are comprised of Air Law and one or two other ones that escape me at the moment. I am in a bind because my military time does not qualify for that clause. I need to go the Commercial route complete with all tests and a checkride. Can't figure that one out...flying a C-130 world wide delivering troops and cargo to combat zones doesn't count for Air Transport Ops. Now I just need to find the time and money to pull that off. I am commited here at work until I retire this summer. Will just have to wait and see.
BTW where are you based out of?
Cheers,
JD
