Sale Sharks have signed Auckland Blues flanker Onosa'i Auva'a until February.
The 26-year-old, who has played for New Zealand at Under-21 and Sevens level, has played 18 times for the Blues since his 2006 debut.
Sharks head coach Tony Hanks said: "He's come through the Auckland system like Sammy Tuitupou and Tasesa Lavea.
"He's got a big engine and has played for younger New Zealand teams. He's a leader and a very intelligent player. We're confident he'll fit straight in."
He added: "When you are bringing someone in the middle of a season, you are looking for someone who can slot in seamlessly and that's what Onosa'i will be able to do.
"It's good timing for him, too, as he's had a few niggles over the past couple of years, so he hasn't had the consistent game time that he would have liked.
"It's a nice fit for him as much as us, as we're going to get someone who is really motivated.
"This is not someone who is ending their career, this is someone who is looking at a new opportunity and who is really motivated to do well."
