Chromecast then?? There's plenty of people selling them here even if they are not "officially" on the NZ Play Store.... well there's no hardware on the NZ Play Store..
The overall number of Chromecast devices in NZ is still pretty low, though and will stay pretty low until an official launch. But Chromecast is absolutely an option.
If you build it, they will come.
EDIT: And a Chromecast is a heck of a lot cheaper than replacing your 2-year old TV.....
Expanding on this - wouldn't it make sense for Spark to sell Chromecast devices? I have no idea as to the practicality (licenses/regions/etc) of this, but it would be a great way to get both Chromecast's into NZ homes, along with a locally created and supported source of content.
Lightbox/Spark - can you comment on this?
i saw a popup lightbox stand in sylvia park in the weekend, if they sold chromecasts and demo'd how you can play stuff from your phone using the android app onto your tv, that would surely be a big hit :D
