From Throng  (http://www.throng.co.nz/soccer/2010-fifa-world-cup-live-on-sky-and-tvnz)

TVNZ and Sky will both have Live coverage with TVNZ broadcasting key matches.

And I imagine that it will be in HD given the previous World Cup feeds were HD. 
Of course this belies the fact that consumers apparently need the Government to intervene in "premium content".
Who would have thought that TVNZ and Sky could be sensible and commercial???

No doubt John Drinnan @ NZ Herald will have this on the front page of Saturdays paper too!
