"The club has invested a lot in me and I look forward to repaying their faith.
“There is a great feeling among the group and we are really hungry to take the next step this season."
“It’s a great sign when one of your emerging players recommits to the club long term as Paddy has done,” Elshaug said.
“He has become a really popular member of our playing group and obviously sees a bright future at the Saints.
“Paddy has shown great character and resilience in the way he has confronted every challenge over the past three years.
“His work on the training track in the latter stages of last season and throughout the pre-season has been first rate and we’re excited by the player he can become in the coming years.”
