I've got this Apple TV 4K 32GB, still wrapped in plastic that arrived today. Ordered it for someone from the USA, but the shipment was held up so they've purchased it locally.
Will have a USA plug, but I've got plenty of cables sitting around so will chuck in a NZ one!
Apparently they're $289 at the cheapest place locally. Would be happy with $255 and I can chuck it on a courier for you :)
