Yeah... NZ is becoming harder and harder to stay loyal too anymore.
I guess when you not AKL based you almost 90% forced to use NZ, being AKL bassed there are more options to avoid NZ which often are more cost effective.
I've taken to taking more of a risk recently on carry-on trips and booking seperate tickets for connecting flights, as the options that NZ are selling ex-AKL are ridiculously stupid.
