oh i forgot,
motoring is really cheap in NZ, you can pick up a used car for next to nothing. A kiwi MOT requires somone kicking the tyres and if it doesnt fall apart it is passed with flying colours. All the cars out there are cheap used japanese imports. Insurance is totally optional and very very cheap. Petrol is less than half what it is here.
It can become quite awkward at times sharing a vehicle between so many people, especially when everyone has a different flying schedule and somone needs to go to the shop and somone has a day off and wants to go out etc etc.
If you can find maybe £500 to put aside to take out with you that should get you a car and make life alot easier. Its quite easy to sell it on to incoming cadets when you leave. I bought a surf bus covered in flowers for about £300. Although it sriously questioned my manhood it did the job and had plenty space for the surf boards.
