You'll be fine. Just act yourself and it should go swimmingly. If your interviewer is a true kiwi, he/she should be quite laid back and relaxed so that should put you at your ease. You might just end up talking about NZ and other personal stuff so it could be quite enjoyable. As long as you know your stuff, and I'm sure you do, there shouldn't be any problems.
I, for one, will be sitting on the edge of my seat, waiting to hear how you got on. Could be another Christchurchian coming up.
Lots of fingers crossed for you.
