Months after Tuivasa-Sheck told AAP that reports of a code switch for 2021 and a possible All Blacks jersey was just "a similar story that happens pretty much every year", speculation is mounting that the the NRL superstar will play out the next campaign with the Warriors before jumping ship.

Tuivasa-Sheck is contracted to the Warriors until the end of the 2022 season, although the final year has an option in his favour.

News Corp has reported that the 27-year-old Dally M Medallist will quit the NRL and turn to rugby with a goal of playing for the All Blacks at the World Cup in 2023.

He would likely play for Super Rugby side the Auckland Blues.

The Warriors have been contacted for comment.

Tuivasa-Sheck was linked to rugby union during last year after the Warriors were forced to spend the season based in Australia due to COVID-19 restrictions, with his partner and two children remaining at home in Auckland.

He is part of the squad in Tamworth before the Warriors relocate to the Central Coast next week.

Tuivasa-Sheck told the Warriors website recently that this time his family will be with him in Australia, from February.

In November, Tuivasa-Sheck trained with New Zealand's Sevens rugby squad which reignited rumours although at that time Warriors boss Cameron George shut down any talk of an exit for the fullback.
