Penrith have won the race for the signature for Apisai Koroisau, who will return to the club next season on a three-year deal.
Canterbury were the favourites to edge out the Warriors for the services of the Manly hooker but the 26-year-old hooker has committed to Panthers until at least the end of 2022.
Koroisau played 16 games at Panthers in 2015 before spending the last four seasons with Manly Sea Eagles.
"I’m thrilled that we’ve been able to bring Api back to the club," Panthers coach Ivan Cleary said.
"I had a high opinion of Api when I coached him previously and his game has only continued to develop in recent years.
"He’s a man of good character and will provide valuable experience and leadership for our young squad moving forward."
As reported by NRL.com last week, the return of former Manly coach Trent Barrett to Penrith in the off-season was helping the club in its bid to regain Koroisau after working with the hooker at the Sea Eagles.
Manly coach Des Hasler was disappointed to lose Koroisau but was confident young hooker Manase Fainu would be a long-term fixture in their No.9 jersey.
"It's a great acquisition for Penrith, I'm very happy for Api," he said. "He's a quality human being."
