World's End owner Cameron Keogh said his bar would be screening the big game and would be giving away loads of prizes in the first half.
"I've got a few kids' rugby jerseys to give away."
Mr Keogh said it was important to support the Steamers because "they're our local team".
He was expecting a busy night and would be wearing his Bay rugby jersey while watching the game.
