Lino has signed a two-year-deal with the Club which sees him in the red and blue until at least the end of 2020.
Knights player list manager Troy Pezet said the addition of Lino provides genuine competition for positions with Lino able to play half and five-eighth.
“Mason is a talented young man,” Pezet said.
“He provides us with good depth… Mason has a lot of strings to his bow.
“Not only does he have a handy kicking game but he’s a sharp goal-kicker too.”
Contracted to the Warriors for next season, the Auckland-based team has agreed to an early release.
