If picked in the team on Sunday, Barnett would become only the second Warrior to play for NSW, after Ryan Hoffman in 2015.
Barnett’s new deal is a boost for a Warriors side hoping to snap their hoodoo against Melbourne at home on Saturday. The Kiwi side have not defeated the Storm in 15 attempts, last tasting victory in 2015.
Barnett credited a change of scenery and Webster’s influence for his purple patch.
“I needed a bit of a change. My form and my career were stalling a bit at Newcastle,” he said. “I wanted to test myself and get out of my comfort zone. I wanted to come here to show my value.
“Webby has come in and I have really connected with him. He just gets it. He gets rugby league. He gets life. He gets the mixture.”
Webster said Barnett’s recent selection in the NSW squad was a fitting reward for the forward’s form amid a tough start to the season.
“Mitch absolutely epitomises toughness, resilience and leadership,” the coach said.
“Through the tough period we endured, Mitch was the glue. He worked so hard and really deserved his Origin call-up.
“He ticks all the boxes. The harder it gets, the better he gets.”
