Summer is coming which generally means summer tourist jobs start popping up. As has already been mentioned the best thing to do is get out there and knock on doors. The AFAP website is good to keep an eye on but just try everyone
Air Carrier Info for Oceania - PILOT CAREER CENTRE
I've found that link to be usefull for finding operators though the list isn't exhaustive. Unfortunately there are a lot of jobless pilots floating around at the moment who've got more time then you so be prepared for disappointment but operators have been known to give jobs to the first pilot to walk in the door so you never know your luck.
Good luck
