The Herald is reporting that the off-contract fullback is poised to sign a long-term deal with the Auckland-based NRL club.
Tuivasa-Sheck had been reportedly considering a shock switch to rugby union and a chance to don the famous All Blacks jersey.
“We’ve talked about it and we’ve certainly talked about it before,” Tuivasa-Sheck’s manager Bruce Sharrock said.
“That’s his background, the All Blacks are a world-recognised team with an amazing success rate. If you thought you were good enough to be a part of it, it’s not a bad ship to be a part of.”
Should Tuivasa-Sheck now re-sign with the Warriors, it would add some stability to the club looking to rebuild following nine-straight defeats to end 2017.
