Depends what you want I guess, if I was 10 years younger I would be applying to Air NZ as it is still the best 'career' airline in New Zealand and most likely will always be the 'only' career airline there.
As someone approaching 40 though then this new Jetstar NZ contract probably offers me the best mix of pay / lifestyle available, if I want to return to NZ as a Captain and not sit in the back seat for 5 plus years. It would certainly take me a long time in Air NZ to be earning that money, have a Christchurch base and not have to do any nightstops. But hey that is the choice I made when I left NZ as a youngster to pursue my flying career. Still I wouldn't change it, best experience I have ever had.
