Flutey joined London Irish from New Zealand Super 14 side, the Wellington Hurricanes, in October 2005 and has played 33 games, scoring 14 tries to date.

He has represented the All Blacks at all age groups and was a member of the U19 team that won the U19 World Cup in 1999. He first played for the New Zealand Mâori in 2002.

"We're disappointed that Riki has decided to move on at the end of his contract," said London Irish Director of Rugby Brian Smith.

"He's been a breath of fresh air at London Irish and we'll miss him, but we do have some very talented midfield players in Mike Catt, Seilala Mapusua, Shane Geraghty, Gonzalo Tiesi, Barry Everitt and Nils Mordt.

"Riki's decision not to re-sign has come as a big surprise so we'll take some time to review our squad and decide if we'll go after another big midfield signing.

"While we were able to match his financial demands, he has decided to leave for other reasons.

"He's been a good citizen both on and off the field at London Irish and he'll play a full part in our fixtures until the end of the season.

Reports are linking Flutey with a switch to premiership rivals London Wasps.

"We thank him for his contribution to date and expect he'll keep performing for us. I'm sure all London Irish supporters will join with me in wishing him well," added Smith.
