FTA has changed drastically since everything went digital. TVNZ has a dedicated sports channel that only has two sports on it at the moment so you'd think they would be keen for content
Although the problem with freeview is that people with sky probably don't even have their TV aerial plugged into their TV so they will only get the main channels.
I think Maori TV would be a good partner personally, it's on every platform and probably won't be as picky about putting content on in prime time weekend viewing.
