At the age of 21, Vos captained Eastern Province against New Zealand in 1996 and played for Queensland Reds in the 1998 Super 12.

"I am delighted to have a player who is still in his mid-twenties and has such a wealth of international experience join us on a long-term basis," said Mark Evans, NEC Harlequins Chief Executive. "Having met with Andre, I am confident he will bring an enormous amount of value to the club"

"It is with great excitement that I take on the new challenge of playing for NEC Harlequins. They have always been a highly respected club that is rich in tradition and to be a part of that will be a great experience for me," said Vos.

"I am very enthusiastic and expectant about working with Mark Evans, whom I believe will take the club from strength to strength."

"I anticipate a very happy and successful time with Quins."

Vos will join Quins at the start of November this year, once he has completed his commitments with the Cats in the Currie Cup.
