Crusaders scrum-half Willi Heinz will join Premiership side Gloucester for the 2015-16 season.
The 28-year-old has 57 Super Rugby caps and also captained Canterbury in the ITM Cup in his native New Zealand.
He is currently out of action after breaking his leg in January.
"I'm trying to get this leg right as quickly as possible so that, when I make the trip over to Gloucester, I'm fit, raring to go and ready to play my part straightaway," said Heinz.
"I've always taken an interest in the Premiership. It's hard, tough rugby and an outstanding competition.
"And there's the chance to play in Europe as well, which is an added draw. It's an intriguing prospect and I'm looking forward to taking part in it."
