Broadcasting on channel 20 on Freeview, it showed live and delayed free-to-air coverage of selected events.
Eric Kearley, TVNZ's Digital Launch Manager, has stated there was no further plans for this channel until the 2008 Summer Olympics.
Sport Extra had originally launched to show the V8 Supercars Series live.
TVNZ however lost the rights to this at the end of the 2007 season to TV3.
It was also the only TVNZ channel available exclusively on the Freeview platform.
