I still can't tell the difference between the OZ and NZ accent, lol, probably lack of exposure to the NZ one.
New Zealand accent is kind of squeaky imo (no offence @piracy ).
The Whites sound may sound Australian-like but the Maoris sound like Afrikaners.
Attached is an example of the Maori NZ accent.
Just my opinion but ask a New Zealander to say seven (they say see-vin).
