Leinster have snapped up the Crusaders' backs coach Andrew Goodman to replace Felipe Contepomi.
Goodman, like Argentina-bound Contepomi before him, returns to the province as a coach having played for Leinster previously.
As an out-half and centre, the Kiwi made 17 appearances for Leinster between 2012 and 2014, winning a Celtic League and the Challenge Cup.
But his second season with the province was badly disrupted by injury and, after retiring, he became head of the Nelson College rugby academy in 2015.
Goodman joined the Tasman Mako coaching team in 2016, before graduating to the head coach role, and last year was appointed backs coach to the Crusaders.
The 39-year-old's appointment has been announced in the week that Crusaders are preparing to face the Blues in the Super Rugby final.
Speaking to Leinster Rugby's website from his Christchurch home, Goodman admitted: "It wasn’t an easy decision to leave the Crusaders.
"It’s an environment that has taught me so much and really embraced my family and I over the past five years.
"However, I am looking forward to being back in Dublin and challenging myself in a new rugby environment.
"It’s going to be special to reconnect with a club I enjoyed representing as a player, and I’m grateful for the opportunity to take the next step in my coaching career."
Leinster head coach Leo Cullen reacted: "Andrew was unlucky with injuries when at Leinster, especially in that second season, but he left a lasting impression and he and I got on very well during rehabilitation sessions that we were both unfortunately part of during that time.
"Since leaving Leinster, I have followed his coaching career very closely and have kept in touch. Obviously, he was with the Tasman Makos, but most recently with the Crusaders and also with the Samoan national team.
"That experience of different environments at club level and international level is something that we hope will add further value to everyone at Leinster Rugby.
"We are delighted Andrew will be joining our coaching group as he is very highly regarded by those who he has worked with. We look forward to welcoming him and his family back to Dublin very soon."
Leinster have been placed among the second seeds for next season's Champions Cup after their final loss to La Rochelle and after losing in the semi-finals of the United Rugby Championship to the Bulls last weekend.
