Jarre, who has played for nine clubs, is “no longer interested” in playing for Australia.
The former All Blacks captain and No 8 jersey wearer is currently rehabilitating from an injury he suffered in a Test in New Zealand.
“No, I don’t see myself playing in rugby league in the foreseeable future,” he told News.
“I’m very grateful to the All Blacks, and I’m just so grateful to my family for supporting me.”
The 26-year-old is the latest of a number of former All Black players who have signed up to join the New Zealand Rugby Union’s elite academy team, which will debut in September.
Former All Blacks lock Jonathan Joseph has been named the squad’s new head coach, while former All Blues lock Jonah Lomu will be the team’s director of rugby.
“This is a massive opportunity for us and we’re going to take it from there,” Joseph said.
“Jonathan Joseph is a great coach and he’s a fantastic man and we want to bring him on board as a head coach.”
Aussie All Blacks forward Lomus, who will also be part of the squad, said he had been asked to join by New Zealand head coach Steve Hansen, but he was “absolutely not” interested in leaving the All Black team.
“It’s great to be a part of this new pathway, the academy and the new era in rugby union,” Lomusesaid.
“I just want to thank New Zealand and the All-Black team for the opportunity they have given me.”
