Harlequins have announced that back-row Mat Luamanu has committed his future to the club after signing a contract extension at the Stoop.
Joining the club ahead of the 2015/16 season, the powerful forward has made 18 appearances since his debut against Wasps in October 2015.
"I am very pleased that Mat has committed to the club going forward. He has made a considerable impact with his physical presence and his professional approach to the game. There is far more to come from him and I am delighted it will be in a Harlequins shirt," said director of rugby John Kingston.
The New Zealand-born former Blues forward added: "I am delighted to extend my contract with Harlequins and I'm really excited about moving forward with this extremely talented group of players. My family and I feel very much at home here and I would like to thank the club for their support."
