To use your existing NZ plan overseas for a fixed daily rate (only if you use the phone on any day) is a great incentive. Usually I purchase a local SIM card which varies in price and is often valid for 30 days.
As most of my trips are short duration, and I don't use the phone everyday, this sort of plan is attractive.
I don't want to move away from 2D as I have been very happy with them.....
