Rugby: All Blacks lock Scott Barrett extends deal with NZ Rugby

All Blacks lock Scott Barrett has recommitted to NZ Rugby through until the end of 2023.

On Tuesday, the 26-year-old confirmed he'd remain with the Crusaders for another four seasons, which would see him through the 2023 Rugby World Cup in France.

Fuelled by the disappointment of the semi-final loss to England at last year's World Cup, Barrett said he hadn't considered any off-shore moves.

"We've been working on this for a wee while and it's exciting to be able to head into the next three or four years in New Zealand," said Barrett.

"I still feel that hurt from losing that (World Cup) last year. It is a big driver to stick around and work towards."

New All Blacks head coach Ian Foster called Barrett's re-signing an important step for the national side.

"This is massive news for New Zealand Rugby and the All Blacks," Foster said.

"Scott has already made an outstanding contribution to the team since making his debut back in 2016 and we know the best is yet to come. 

"It’s really exciting for the future having him re-signed."

Barrett and Crusaders colleague Sam Whitelock are expected to be the preferred test locks for the All Blacks when the test season eventually begins, but he's set to face a huge challenge to hold that starting spot when Brodie Retallick returns from his sabbatical next year.

Nevertheless, he's determined to forge a leadership role in the national pack, which includes taking charge at setpiece.

"I would like to put my hand up and take charge of the second row in the All Blacks and that is certainly a big challenge," Barrett added.

"It is something that excites me, to be able to potentially lead a pack at All Black level. And run the lineouts."

While Barrett has no sabbatical clause written into his new deal, he will be able to make a late start to a Super Rugby season if need be.

Last month, Barrett dispelled any suggestions he'd be shifting north to join brother Jordie Barrett at the Hurricanes, hinting towards a long-term commitment in Christchurch.

"I'm enjoying my rugby down here and now I've been captain of this team," he told Newshub. "It's certainly where I'd like to see my rugby be played in New Zealand."

Barrett will captain the Crusaders when the revised Super Rugby Aotearoa competition begins next month.

He becomes just the sixth All Black to re-sign through until the next World Cup, alongside brother Beauden Barrett, Retallick, Whitelock, Anton Lienert-Brown and Tyrel Lomax.
