Corey was banished for the remainder of the 2016 NRL season after pleading guilty to drugs possession.

The 25-year-old had been one of the club’s best on the park in recent seasons, directing play with class and precision.

Eels coach Brad Arthur said that consistency and hard work over the past three years would mean Corey’s best footballing years are ahead of him.

“Corey has progressively improved his game over the first three years at the club and in 2016 showed how valuable his contribution is in the success of our team," he said. 

“Through today’s announcement Corey has showed his commitment to the future direction of our Club and I have no doubt he will play a major role in moving our team forward over the next three years."

Eels Chairman Max Donnelly touched on Norman’s off field controversy.

 “We have been pleased with how Corey has responded to the personal challenges of this year and we look forward to his contribution to the clubs success over the next three years," he said.
