Warriors chief executive George Cameron told AAP the 23-year-old would re-sign for the club, despite turning down an earlier offer and attracting interest from at least three other clubs.
The deal caps off a big week for Tevaga, who was named Interchange Player of the Year at the Dally M awards.
The Warriors will now set their sights on re-signing Issac Luke.
The fullback’s current contract has expired but reiterated at last night’s Dally M awards that he wants to remain at the Warriors.
“My manager is doing everything he can to get a really good contract. In saying that, I am happy where I am and obviously I want to stay.”
