Sea Eagles head of football Bob Fulton said the club was pleased with the deal.
"Martin Taupau is one of the best forwards in the world and he will only get better," Fulton said.

The 26-year-old former Bulldog and Tiger played 20 games in his first season at Manly, averaging 142 metres per match.
Taupau will be representing New Zealand at the upcoming Four Nations.
