TV3 have secured the broadcasting rights for the RBS 6 Nations from 2018.
The four year-deal will run until 2021.
The news was confirmed in an official statement from the Six Nations. It read:
TV3 will broadcast live coverage of all matches in the Championship as well as previews, magazine and highlight programmes.
TV3 will also broadcast delayed match replays of all matches to complement live coverage to give maximum exposure to Rugby’s Greatest Championship.
This follows the broadcaster staging all 48 of the recent Rugby World Cup live during September and October.
