Hurricanes' scrumhalf joins Leinster

The 24-year-old has played for the Maori All Blacks and was part of their squad that toured England in 2012.

Leinster have also confirmed that Hayden Triggs has extended his contract and will remain with the club for the 2016/17 season.

Commenting on the new signing and the additional extension, Leinster Rugby coach Leo Cullen said: "We are very happy to have secured two key signings ahead of next season.

"Jamison, for a young player, has a wealth of experience behind him already and was an ever-present in the Blues team last season in Super Rugby before signing with the Hurricanes.

"[Meanwhile] Hayden has been influential since joining us earlier this season and we are probably only now seeing the best of him as he unfortunately suffered that ankle injury against Bath in the Champions Cup.

"In 14 games for us to-date we have seen the leadership that Hayden brings to this team as well as his excellent work ethic with and without the ball,"

The coach also confirmed that Leinster hope to finalise the remaining squad positions and the full roster for next season in the coming weeks.
