All Blacks sign promising flanker Anton Segner until 2031

The versatile 25-year-old's four-year contract extension makes him the first All Black to sign through to the 2031 Rugby World Cup in America.

Anton Segner said he was grateful to have his career and location locked in for another four years with teams he cares deeply about.

"Signing a long extension with the Blues, Auckland Rugby and New Zealand Rugby gives me a long-term idea of where I'll be playing my rugby and there's no place I'd rather be than here in Auckland," Segner said.

"I have spent a huge chunk of my life in the ‘09 and it's that place that has given me so many opportunities. This is my home away from home and I absolutely love it here. I'm very grateful to have been given this opportunity. Playing under Alfie [Blues Head Coach Jason Holland] is something that excited me as well as the direction of New Zealand Rugby as a whole, so it was a no brainer."

Born in Frankfurt, Segner moved to New Zealand in 2017 as a 15-year-old exchange student at Nelson College and realised his dream or becoming an All Black in July during a 47-17 win on debut against Italy at Hnry Stadium in Wellington.

His new contract comes off the back of an international season that's included two Test caps and two strong performances against the Stormers and Bulls in South Africa before an ankle injury ended his tour early.

All Blacks Head Coach Dave Rennie said Segner's decision to commit long-term showed the kind of player and person he is.

"Anton's a great example of what this jersey means to people. He left home at 15, backed himself, and has worked incredibly hard to get where he is. Committing through to 2031 shows how much he wants to be part of this team.

"Anton is a hell of an athlete and has physical presence both sides of the ball. His anticipation post-tackle, versatility and work ethic are genuine points of difference. This is a great signing for New Zealand Rugby."

Leadership has been a feature of a career that's seen Segner captain New Zealand Secondary Schools, Crusaders U20s, Auckland's NPC team, and most recently the Blues in 2026.
