Harlequins have announced that New Zealand-born back-row Mathew Luamanu has signed for the Premiership club, who joins from Treviso.
The powerful and abrasive number eight made 22 appearances in 2014/15.
"I'm really excited to have joined Harlequins and I'm looking forward to the challenges ahead while beginning a new chapter," said Luamanu.
"Harlequins' style of play is known throughout Europe and that was something that really appealed to me.
"It's a long pre-season, so there is a lot of work to do but I've enjoyed it so far and I'm looking forward to getting some game time under my belt."
The 27-year-old previously represented New Zealand Schools and won the 2008 Junior World Cup with New Zealand U20s.
Making his senior Wellington debut in 2008, he transferred to North Harbour for the 2010 ITM Cup and played alongside current Harlequin Ben Botica.
Luamanu shone during that season and was called into the Blues Super Rugby side in 2011, helping the franchise to its first play-off appearance since 2007.
In 2012, the 127kg forward moved to Japanese side Kyuden Voltex before transferring to Italy in 2014.
Confirming the announcement, Harlequins director of rugby Conor O'Shea said: "In any squad you are always looking for a point of difference and we have no doubt that Mat can provide us with that.
"He needs to work hard through this pre-season but I'm confident that will happen given what his motivations are.
"Mat's sheer size, power and footballing ability will provide a very interesting challenge to teams in the Aviva Premiership and in Europe and we look forward to working with a player whose best years can still be ahead of him."
