The Kiwis could have done with Mannering's leadership as momentum shifted against them early in the second half. The players on the park looked powerless not only to arrest an Australian side growing in confidence but also ensure they settled things down - the Kiwis completed just three of their 10 sets in the second half.
Coach Stephen Kearney is trying to build a strong leadership group but many of those members were missing this week, including former captain Benji Marshall and Jeremy Smith. One member, Frank Pritchard, had an excellent game except for conceding a couple of penalties for shoulder charges and the Kiwis lost potency when he had a spell on the sideline. Jesse Bromwich, Issac Luke, Ben Matulino, Alex Glenn and Jared Waerea-Hargreaves are part of an emerging leaders group.
Five-eighths Kieran Foran captained the Kiwis in the absence of Mannering.
He led well, often bossing his team-mates around the park but also remonstrated with referee Ashley Klein.
"It was certainly a game of two halves," Foran said. "I just tried to lead from the front. It was the proudest day of my football career. As a kid I dreamed of leading New Zealand out. [On Friday night] that dream came true.
"I just wish I could have walked off a winner."
Mannering might say that at least he walked off.
