"Gareth has long been considered one of the greatest rugby players of all time and is an icon within our game. Since finishing playing he has continued to hit the headlines with his work in business and charity and a CBE is just reward for his continued contribution to Welsh life.
"Paul's OBE is a tribute to his great work at the Millennium Stadium over the past three-and-a-half years. It will provide him with a marvelous send-off as he prepares for a new life Down Under with his family."
Paul Sergeant added: "This is one of those things you never expect to happen to you and is a humbling experience. It is testimony to the hard work of the management team and all those involved with the Millennium Stadium who have made things work during what has been an immensely satisfying, albeit often stressful, time."
