With the Kangaroos struggling for fluency and lacking aggression, Taupau's powerful charges and strong right-hand fend kept defenders at bay and allowed him to offload to support runners to kick-start the Kiwis' second-phase attack.

A second try to left wing Manu Vatuvei soon followed and three minutes later halfback Shaun Johnson crossed for their third four-pointer to make it 18-6, but Taupau was just getting started.
Shortly after, with the Kiwis hot on attack, Taupau was caught in what looked like a crusher tackle from Kangaroos forward Sam Thaiday, before angrily climbing to his feet and directing a throat-slitting gesture at his green and gold rival.
His fiery demeanour spelled the difference between the two sides and typified the Kiwis' firm confidence and belief after their successful end of year campaign and back-to-back wins over Australia.
He finished as the Kiwis' most effective forward, with 135 metres from 12 runs, three tackle busts, two offloads and 13 tackles capping a memorable display.
Following Johnson's successful penalty goal, the Kiwis' big men powered back up-field once more to create the roll-on in the lead-up to centre Shaun Kenny Dowall's try right on halftime when he dotted down after a defensive blunder by Australian fullback Greg Inglis.
The second-half saw the Kiwis produce a terrific defensive effort to quell any chances of a Kangaroos' comeback. But the damage was done during Taupau's explosive 20-minute first half spell, which set the Kiwis on course for their historic three-peat.
