Mate, I'd cut out the middle man and ask the RAAF/RAF your questions.
But, just in case your query is genuine... I'm sure you are aware what the PM has done to the RNZAF and if, despite all of that, you still want to be part of it, then good luck to you. Some of the boys should still be able to give you a run down on the positive side of the RNZAF - most of the ones I know enjoyed the job until recent developments. And, being from Auckland myself I assure you there's no place like Godzone. Nought wrong with Craccum or scarfies, either.
If you want to come over and fly for the RAF then don't be afraid to look into that option either. There's a commonwealth scheme for the likes of you and I (and I enjoy the flying AND the job, but don't tell anyone).
Cheers
Stray Fin
