Former New Zealand and Wales coach Graham Henry will lend his vast experience to Leinster next season after agreeing a consultancy role with the Pro12 side.
Henry, who won the Rugby World Cup with the All Blacks in 2011, will join ahead of the new campaign to assist head coach Leo Cullen.
The 70-year-old will remain with the province for "a number of weeks" before the season starts, Henry taking a similar role to the one he agreed with New Zealand Warriors in May.
"This isn't by any means a first for Leinster Rugby and I felt it was important for myself and the wider coaching and playing staff in Leinster to look at different ways of challenging ourselves," said Cullen.
"To that end I am delighted that Graham has decided to work with us and I would like to publicly thank the Professional Games Board in Leinster for their support with this decision.
"Everyone in the organisation will benefit from his expertise and undoubtedly the coaches and the players will benefit from having a coach of his stature in and amongst us as we build towards the new season."
Leinster lost the 2016 Pro 12 final 20-10 to Connacht.
