Vatuvei played in 226 NRL games for the Warriors, scoring 152 tries and earning 29 test caps for the Kiwis as well as two test caps for Tonga.
He parted ways with the club in 2017 to take on a deal with Salford in England, but returned to New Zealand after playing just eight games for the club.
Upon his return, he looked to launch a career as a professional boxer, however he revealed to the Herald in June a brain cyst meant he was unable to follow that path.
"[There were] no symptoms, no nothing … They found it then and tried to rule me out of the fight but I went on with it and came out good."
He won his debut by knocking Letele out in the first round of the fight, but other bouts he had lined up were cancelled because of the discovery.
Vatuvei, affectionately known as 'the Beast', recently won the hearts of the country on his way to winning TV contest show Dancing with the Stars.
The offer to participate in the most recent season of Dancing with the Stars opened a new avenue to express himself and exert himself physically. It was something totally new, and he quickly embraced it - going on to win the competition.
"It was a tough challenge for myself and I've enjoyed it," he told the Herald in June.
"I got told I can't do boxing anymore. It's been tough, but then dancing came along and made it feel a little better so I'll just continue with that and see what the future holds for me."
