Most the newer Krell products have chip that detects the voltage frequency and it will not work if the frequency is different. Since you bought the unit in the USA, the chip will be looking for 60 Hz and NZ has 50 Hz so it won't work.
You can contact Krell and see if they will sell the 50 Hz chip which I don't think they will. The other solution is to use a PS Audio Power Plant P300 which has frequency adjustment and also take care of the 230V to 120V step down issue as well.
