New Zealand forward Steven Luatua will re-unite with his former Super Rugby coach Pat Lam at Aviva Premiership strugglers Bristol next season.
The 25-year-old, who plays for the Auckland Blues, won his 15th cap for New Zealand against Italy in November.
Bristol, who are currently bottom of the Premiership with two wins from 14 games, have not indicated the length Luatua's contract but the player stated he was looking forward to contributing to the club's "long-term vision".
Luatua said: "I have a fantastic relationship with Pat and I enjoyed working with him at the Blues.
"I've heard great things about the environment that is being built there and the plans in place, so I can't wait to get started in the summer."
Luatua has played most of his Test rugby as a blindside flanker, but is a capable No 8 and can also play in the second row.
Although aware of Luatua's move, Bristol's announcement blindsided the Blues, who have declined to comment.
But New Zealand coach Steve Hansen claims he did not have an opportunity to talk with Luatua about his future and took a swipe at compatriot Lam.
"In this case it's double disappointing because of the lack of communication," Hansen said.
"Steven's crew didn't want to talk because they are fearful we are going to change these guys' minds.
"And he's been tapped on the shoulder by Pat Lam which is disappointing, too. If you're an ex-New Zealander you should be a bit mindful about players' careers."
