Warriors chief executive Cameron George said he and Webster shared the same “vision, passion and commitment for success at our club on all levels.”
“Andrew has confirmed to us that he’s the right fit for our club and his skills as a coach are what we need to cement our long-term development through our pathways. He did an extremely good job this season and we have every confidence that he’ll continue to grow into the role.
“Another important element of extending his contract is that the stars of the future can see stability in long-term planning in the head coaching role and they see a coach who is driven to develop players of all age groups to become NRL players of the future for the Warriors.”
As well as Webster claiming the coach of the year accolade, halfback Shaun Johnson came within a whisker of winning the Dally M Medal while he was named in the Dally M Team of the Year along with winger Dallin Watene-Zelezniak and prop Addin Fonua-Blake.
Tohu Harris (lock) and Wayde Egan (hooker) were finalists for their positions and Harris was also a finalist in the captain of the year category.
Johnson was voted by his peers as The Players’ Champion, Fonua-Blake was a finalist for the award and Johnson, Watene-Zelezniak and Fonua-Blake all made the RLPA Dream Team.
