Yates has been a consistent performer for the Hawks since joining the south Leeds side at the start of 2011.
Director of rugby Darren Williams was full of praise for the 22-year old.
He said: “In my opinion Andy would get a start at any Championship club and his improvements this year have been for all to see.
“He’s got a great engine on him and his work rate is second to none. He regularly earns penalties with his upright running style and it’s a massive coup for the club to be able to retain his services.
