For anyone going through selection just make it clear that you are wanting a career as a pilot more than anything else. Don't forget to smile and also use a bit of well placed humour. Try to think of plently life examples before you attend for subjects such as teamwork and leadership and put across the fact that you have other interests such as sport or music.
For those heading out to NZ in the near future, it's an awesome experience and when you've been back for a year and flying for an airline you'll miss the fun times you've had out there with your course mates. Enjoy.
