After Australia kicked off, New Zealand error in the first set of the game led to an early opportunity and field position for Australia, and the penalty was kicked by Johnathan Thurston to open the scoring to 0-2. Further play from the Kiwis brought them into the Australian half of the field, and a holding penalty then given by the Australians was kicked by Shaun Johnson to level the score to 2-2 at the 16 minute mark. Despite Old Trafford having an in-goal area of just 4.1m, Australia were able to force a line drop-out. From this, Thurston was able to kick to Billy Slater, setting up the first four-pointer which Thurston also converted to make the score 2-8. A try attempt by Cooper Cronk was controversially  disallowed by the video referee, who ruled Isaac Luke had been able to stop the ball coming into contact with the in-goal grass. A few more minutes led to a successful try by Cronk, as Darius Boyd's grubber kick found him space and Thurston again converted to 2-14. Manu Vatuvei's attacking run for New Zealand saw him pushed over the sideline, and an offside penalty at the 35 minute mark gave Thurston another kick to bring the score out to 2-16 at halftime.
Billy Slater opened the scoring on the first set of the second half, thanks to a run down the sideline from winger Darius Boyd, giving Thurston another chance to convert and bring the score to 2-22. A charge-down by Ben Matulino and regather from Sonny Bill Williams led to New Zealand beginning attack at halfway. More potential attack from the Kiwis was defused easily by the Australians, until a New Zealand grubber gave possession back to the Australians. A flick offload from Josh Papalii led to a chip kick from Brett Morris, regathered and then re-kicked by Jarryd Hayne led to a sliding Morris try. A conversion by Thurston brought the score out to 2-28. Both teams were having issues with the geography of the ground, as Morris collided with the signage during his try and a flying Manu Vatuvei landed awkwardly on the concrete surrounding the field. Australia's control of the game led to the New Zealanders forced into defense of their own line, defusing Australia's attack but not managing any successful attack of their own. A near 100 metre try by Morris, thanks to the efforts of Hayne, and conversion by Thurston made the score 2-34 with eight minutes to go.
Australian scrum half back Johnathan Thurston was named the final's man-of-the-match, his fourth such award of the tournament.

The 32-point margin set a new record for heaviest victory in a final, eclipsing Australia’s 40-12 victory over the Kiwis in the same stadium in 2000.
