Disregard everything AlexWCD has stated.
Avoid everything to do with the Air NZ Scheme it's got future shafting written all over it! It's all about Air NZ not you.
Stay away from everything to do CTC they are a bull****ting marketing department. They suck up to Jetstar to make they're fat little profit on your training.
Stay away from the Jetstar Cadet scheme, it is a slave labour scheme in disguise. A middle management accounting bonus project. Making some fat cats look good to the board? At your expense long term. You're a fool if you go anywhere near it!
I highly recommend becoming a dodgy accountant or what ever and buy your self a toy and fly in the weekends......but if not...
Go to a good old flying school get a student loan if you can (it's interest free!) do all the fun flying go fly around Mt Cook, Queenstown, Milford Sound etc enjoy your training. Try even getting a job down there for a season or two? do some skydiving, banner glider towing. It will better for you long term skill wise and respect.
Stay away from flying with C cats that have had no exposure to the outside of their flying school.
Then get over seas as quick as possible! avoid the whole Eagle, Air Nelson scene. There is a huge wide world out there great adventures, better machines and more money than NZ.
It takes a big step to leave the safety of little old NZ but once you do you will forever better off.
