Aim High
If you are sure that there is a market for jet charters in NZ, then continue as planned. Were you meaning Turboprop or Turbojet charters? The best way is to be company pilot on their own aircraft.
Maybe you could suggest to the Government to invest in their own airline that you could fly - oh whoops, they already own ANZ. Maybe another corporate company that operates NZ wide and wants to have a good profile? Why not Fonterra or Toll Rail or someone like that?
Turbojet - only practical in the main centers
Turboprop - almost as fast with a better payload, range and flexability.
