~$74/$80 NZD if you want to avoid the New Zealander tax on this preorder. PS5 RRP at NZ retailers is $119, with the cheapest I could find at $98 (including Mighty Ape’s own NZ website).
Even though it is from mightyape.com.au, I suspect they still deliver it from their NZ warehouse. Delivery said the standard 1-3 days to Auckland at checkout and was only $4.50 (was $5.90 shipping to AU, which would make no sense if this was actually shipped from AU in both cases).
Amazon AU is the same price, but delivery time will be slower to NZ.
Also, with Amazon AU and Mighty Ape AU deals becoming more accessible for us, I’d suggest getting a TransferWise card for the long run if your bank has high fx fees (make sure to use a referral!)
