Canberra have come home with a wet sail to down the Warriors 42-22 in Auckland and go into the NRL playoffs with their winning form intact.

The Raiders have now made it five wins in a row as they head into an elimination final next weekend.

Down 22-6 at halftime on Sunday, they took full advantage of the breeze at their backs to score six second-half tries, with Blake Ferguson and Reece Robinson each getting a double.

Canberra made light of being without two key players in fullback Josh Dugan and halfback Sam Williams, who failed late fitness tests for ankle and shoulder injuries respectively.

Their comeback began when lock Shaun Fensom busted up the middle and powered over early in the second half.

Robinson, moved from wing to fullback for Dugan, edged the visitors closer when he sliced through a gap to score.

When winger Sandor Earl reined in a Shaun Berrigan kick to set Ferguson for his first try, and Jarrod Crocker landed his fourth conversion, the visitors hit the lead for the first time.

Canberra kicked on, with Ferguson, Robinson and second rower Josh Papalii adding further tries to leave the Warriors routed.

The defeat was a club record eighth in a row for the Warriors, who have made a habit this season of giving up big leads.

Winger Manu Vatuvei opened the scoring in the eighth minute courtesy of a bust by impressive prop Ben Matulino.

Canberra replied when Berrigan, in for Williams, latched on to a Josh McCrone kick-ahead to dot down.

From there, the home side pulled away, with Matulino, Vatuvei and Godinet all touching down, but their 16-point halftime lead proved to be way short of enough.
