NZ 2 really doesn't have that much TV value in itself.
Good luck getting more out of our TV stations, given that Sky are the only ones with cash - and they can pay whatever they like, knowing they won't be outbid.
Plus the Warriors appear to have little-to-no value to Australian TV (FTA just ain't interested in them), and an NZ team doesn't offer any new timezone for scheduling - though admittedly it DOES help plug that awkward 6pm Eastern time Friday slot, that no Aussie team likes hosting games in.
