Zane Kirchner will leave Leinster at the end of the current season to join Welsh side Dragons.
During a career that spanned four seasons in blue the 31 times capped Springbok made 82 appearances for the province, scoring 11 tries.
Opening up about his decision to leave, Kirchner said: "New decisions and ventures aren't always easy to make. However the experience of moving to Leinster, my first move abroad, has helped and knowing a few of the other South Africans in the Dragons squad makes my decision easier.
"To the Leinster blue faithful, I hope that even for a little while I brought joy to your presence at our games. The roar and memories of the RDS is something I'll carry and treasure for the rest of my life.
"I am very grateful.”
Leo Cullen paid tribute to the indelible mark left on the province by the 32 year old back has had on the club.
"Zane has played a key role in his time with Leinster. I will always remember his two tries in the PRO12 Final against Glasgow at the RDS as they paved the way for us to win the game, a game that happened to be my last ever game of rugby played.
"We would like to thank Zane for the contribution that he has made to Leinster Rugby.
"We wish him and his family the very best of luck with their move to Wales and look forward to meeting him when we take on the Dragons next season. I am sure all the fans will give him a warm welcome when he returns to the RDS.”
