Winger George Bridge scored two tries in the space of three minutes in the second half to help the Crusaders beat the Highlanders 32-22 on Sunday and clinch the Super Rugby Aotearoa title with a match to spare.
The Crusaders moved to an unassailable 28 points, six ahead of the second-placed Blues, who host the Christchurch-based side in the final game of the domestic competition next Sunday.
The match was played at a frenetic tempo with the Highlanders taking a leaf out of the book of the Hurricanes, who beat the Crusaders two weeks ago, by refusing to take a backwards step and seize their points-scoring opportunities.
Loose forward Shannon Frizell scored a second-minute try after the Highlanders turned the ball over with an aggressive counter-ruck, while winger Jona Nareki made a crucial intercept and ran 80 metres untouched for their second try.
Crusaders' fly-half Richie Mo'unga was responsible for all of his side's first-half points with a converted try and two penalties that left his side only trailing 17-13 at halftime.
Michael Collins extended the Highlanders' lead to 22-13 with 25 minutes remaining, but the home side grabbed the lead for the first time when Bridge crossed twice to give them a 25-22 advantage.
Braydon Ennor then put the match beyond doubt with five minutes remaining when he crossed for his side's fourth try.
