The prodigiously talented forward’s contract expires next season and the Cowboys have already begun negotiating with his management to extend him long term.
But the club will have a fight on its hands to retain Taumalolo. It is understood two other clubs are chasing his signature.
Cowboys coach Neil Henry said he wanted the 110kg monster to become a first-grade regular next year.
Henry said he had recently been in the ear of the 191cm Auckland native about staying with the club, which he was signed to as a 15-year-old.
“I’ve been in his ear, trying to get him to commit to the Cowboys,” Henry said.
“He’s a young player we hope stays with us for a long time – the same with Tariq Sims, who we re-signed recently.”
Taumalolo’s manager Chris Orr confirmed his charge was hopeful of securing a three-year deal with the Cowboys.
