Unfortunately, the rules is the rules:
BECOMING A MEMBER
3.1 Becoming a Member: Becoming a member is free. You may only register as a member if you are resident in New Zealand or Australia and can form a legally binding contract that is enforceable against you.
Holiday accomodation is dealt with by a sister company and links to
http://www.travelbug.co.nz/ which you would need to register with separately anyway and the same conditions do not apply.
For job adverts, you do not need to be a member, the listings are to all intents like any other classified ad and will give the e-mail or phone contact details of the advertiser.
