The halfback found Anton Lienert-Brown who gave it to Shaun Stevenson and he passed it to Sean Wainui who scored in the corner.

The home side never gave up, throwing passes and keeping the ball alive.
A Marty McKenzie cross-field kick found Alex Nankivell who passed the ball to a supportive Tumua Manu to score the try and give the Chiefs a shot to win the match.
