Api was released by the Panthers. He played a lot of footy this year in the 9 due to Seg being out injured as

Penrith Panthers release hooker Apisai Koroisau to join Manly Sea Eagles on three-year NRL deal

Premiership-winning hooker Apisai Koroisau has been released from the final year of his Penrith contract to take up a three-year deal with NRL rivals Manly.
Penrith said it would not stand in the way of the club's back-up number nine shoring up his long-term future with another club.
After playing in South Sydney's grand-final win last season, Koroisau moved to Penrith this year on a two-year contract.
He has been stuck behind first-choice rake James Segeyaro at Penrith and, at Manly, he will be down the pecking order behind veteran Matt Ballin, who is off-contract at the end of 2017.
"Api has been given an opportunity to secure his future and he leaves with our blessings," Panthers general manager Phil Gould said.
"He has been wonderful for our club in the short time he has been here, and I know he will continue to give us great service for the rest of the season.
"With James Segeyaro also at the Panthers, it is only fair that we give Api the opportunity to secure a regular starting position with another NRL club."
