Jeez. How hard can it be? They get the tires they stock from somewhere, why can’t they specify the inclusion of one of these in their next shipment?
They’re treating NZ like it’s on another planet.
I’d be pretty frustrated.

 

I am going to Australia - Gold Coast for Supercars Street Racing in October and will be bringing one back in my check-in luggage! Weight is only 6KG (13 1/2 pounds) and I have a free bag due to airline membership)
Ironically there is a SuperCheap Auto Shop very near the circuit and they source their tires from Tyroola Australia!
