Samoan flanker Ray Ofisa will leave Irish province Connacht at the end of the current campaign.
The 31-year-old joined Connacht from North Otago in 2007 and won his 100th club cap earlier this season.
"He can turn a match in a flash with a moment of brilliance," said Connacht coach Eric Elwood on Friday.
Connact captain Gavin Duffy has signed a contract extension, keeping him at the Showgrounds until at least 2014.
Henry Fa'afili, Dermot Murphy, Dylan Rogers, Jamie Stephens, Brian Tuohy have not been offered contracts for next season.
