Here’s the non-primary locale in action, you can see the /nz/.

I think what you’re asking is how the user should choose which locale they want, and the answer is the Locale Switcher element which I don’t see on your page.
That said, there’s not much locale difference between AUS and NZ. I’m not sure what the value of localizing is here- different photos might be the biggest benefit?
It’s currently not showing different pricing but you certainly can.
If the domain name will be general ( e.g. .com ) or a ccTLD like .com.au, you might need to specify NZD with the NZ pricing, or it’s assumed to be USD or the price relating to the ccTLD such as AUD.
If the price difference is substantial it could annoy users to see the other’s pricing. If that’s the case, it’s common to split the domains, and geo-block them.
