Hi Niagra1 - congratulations on your place!
You will shortly recieve several emails explaining all, but CTC do provide flight bag, uniform (except shoes), etc at your 'Meet and Greet' day which will be held a week or two before your departure.
I'm flying out in September so will see you there. There's a CTC social thread down on page 5 of the Interviews, jobs & sponsorship forum - probably better of using that for any pre-NZ banter or feel free to pm me.
