World Cup-winning former All Black Richard Kahui signed for Super Rugby AU franchise the Western Force on Tuesday, saying the move had reignited his love of the game.

The 35-year-old, who has spent the past seven years with Toshiba Brave Lupus in Japan's Top League, said he had immediately bonded with his new teammates.

"Everyone's really one team here, everyone's really connected," he told rugby.com.au.

"There's a really good culture of hard work and it's really made me excited about playing footy."

The outside back earned 17 caps for the All Blacks, including a victorious appearance in the 2011 World Cup final, before helping the Chiefs to the Super Rugby title in 2012.

Force head of rugby Matt Hodgson said Kahui's experience would be invaluable for the team, who have rejoined Super Rugby after a two-year absence from the competition.

"His knowledge of the game, defensive ability and the level of professionalism he brings to training will be huge for our season, we can't wait to see him out there in the blue and black," he said.

The Force were ousted from Super Rugby in 2017 but received a lifeline when Australia launched a domestic version of the competition after the coronavirus pandemic halted its international fixtures.

They lost their opening match against the Waratahs 23-14 on Saturday and face the Reds in Brisbane on Friday.
