Starting 1 July - as per http://dannews.co.nz/2012/06/17/tv-one-1-to-broadcast-on-sky-tv/
At the moment, a placeholding screen is on 81.
With this and Choice TV coming to Sky, wonder if TV3 +1 and C4 will take the leap too?
They're already on Freeview Satellite transponders, so it wouldn't take from any Sky capacity... it just needs some sort of agreement between Mediaworks & Sky.
