If anyone is concerned regarding compatibility, here's the official google list of Pixel models and the 5G standard they work with.

So if 5G is a must, one must confirm with the PI shop the exact Model ID before purchasing.
AFAIK, even if the phone you get from AU meets the NZ 5G requirements, the service provider has to support Pixel 6/6 Pro, otherwise the settings won't get pushed/activated to your phone.
And that's the problem here the carriers don't want to know about the pixel.
