Do you have NZ citizenship / residence / work permit? Discussing the whys and wherefores of NZ jobs or licence is kind of pointless if you haven't got that.
Having said that, myself and many hundreds of my fellow countrymen left NZ in recent years due to lack of jobs. I'm now long haul in the middle east, I don't know if staying out here is the answer but I have got NO intention of returning before my retirement, due to the utterly pitiful and pathetic job scene down there both in terms of available jobs and pay.
