Williams calls on Kiwi brain-power

New Zealand superstar Sonny Bill Williams says his team must use their brains as well as brawn in Friday night's Centenary Test against a star-studded Australia at the SCG.

The Kiwis lost their last encounter with the Kangaroos 58-0 and are determined to restore some pride in the black jumper.

Williams says it is important New Zealand keep their heads and keep focused on the game for the full 80 minutes.

Coach Stephen Kearney says he will determine the final make-up of his team in the coming days.
