A quick response - take your phone with you, if it is a recent model that is unlocked and is a Contract phone - and then purchase a SIM card there for use in NZ. More info here:
Leave your own sim somewhere safe, unless your phone is a dual-sim model (and can accommodate 2 sims in it at the same time).
Enjoy the time in New Zealand, @FARMER_1998!
