Penrith Panthers prop James Tamou has signed a two-year deal with the Wests Tigers.
The 31-year-old - who has represented NSW and Australia - will join the club for the 2021 and 2022 seasons.
Tamou previously played with the North Queensland Cowboys in their premiership-winning 2015 squad.
The New Zealand-born forward has amassed 263 games in his career so far, and is in his 12th season of first grade NRL.
He averages 146 metres per game and has a 96 per cent tackle efficiency rate.
Wests Tigers coach Michael Maguire said Tamou would be a brilliant addition to the squad.
"James brings a wealth of experience to our forward pack and is a player who has experienced success at every level of the game," he said.
"He has shown throughout his career to be a player who constantly improves not only himself but those around him, and I have no doubt he will play a key role in the development of our forward pack moving forward."
Chief executive Justin Pascoe welcomed the six-foot-five rep player to the club.
"On behalf of all at Wests Tigers I'd like to welcome James to the club and say how pleased we are to secure a player with his experience and talent for the coming two seasons," he said.
"James has shown to be one of the leading fowards in our game and has generated extremely strong metres-per-minute this year, which will greatly complement our current squad.
"He is a highly-commendable man both on and off the field and he will certainly have a strong impact at Wests Tigers in driving this club forward to where we all want it to be."
