North Queensland have re-signed try-scoring centre Ashley Graham to a new three-year NRL deal.

Cowboys executive director Peter Parr was thrilled the 24-year-old Graham had elected to stay with the club long term.

"This is a wonderful signing for the club," said Parr.

"Ashley has played his best football at the Cowboys. He's a North Queensland product who'll continue to improve under the guidance of (new coach) Neil Henry."

Graham has the impressive strike rate of 35 tries in 58 games for the Cowboys who signed him on spec in 2006.

He has quickly developed in a danger player in the Cowboys backline alongside Johnathan Thurston and Matt Bowen.
