If you want to stay in NZ however, your choices are to either get your C cat - instructors are in big demand. Or head somewhere like Queenstown or Wanaka, do a Mountain flying course with the local aeroclub and start door knocking around the scenic operators.
I know it is hard to find more money to pour into your flying when you think the hard work is done.... but welcome to NZ Aviation! I guarantee it wont stop there.
You could try somewhere like "Wings Over Whales" in Kaikoura, or "skydive the Sounds" in picton, both take entry level pilots, and since both are owned by Soundsair you would probably move through to driving the Caravan IFR for them after a 1000 hrs. Better than instructing anyway!
