The New Chromecast with Google TV is out in the USA.
However, without a VPN Google TV is not so useful in NZ, which means the Chromecast Ultra is probably still a good purchase.
Currently available Noel Leeming for $88 plus shipping, with an additional $10 off if you use coupon code AMAZING10, with free shipping if you sign up for the Vodafone / The Market deal previously posted.
If you've ever wanted a Chromecast Ultra, now is your chance, they are out of stock everywhere in the USA and many other parts of the world.
Why would you need a VPN for Google TV? It's for sale in Australia. Isn't it essentially Android TV?
