“He’s a New Zealand international and I believe would have been capped far more only for his injury issues which were well-documented at the time but he has been back playing now a number of years and you could see even in the Challenge Cup final in Marseille just how influential a player he is.

“The important element for us I think when you look at some of the experience we are losing out of the environment this season with departures and retirements, is that Charlie will be an ever-present figure around UCD and will be a great asset to our Younger players in terms of his leadership and experience.

“We look forward to welcoming Charlie and his young family to Dublin very soon.”

Speaking to leinsterrugby.ie, Ngatai said, “I’ve had a great few seasons in Lyon but I’m now excited to get started in a new environment, a new team culture and to take on new challenges.

“I’ve had a few good chats with Leo and it will be exciting to play alongside some new and also some familiar faces.”
