The Crusaders, with No8 Jordan Taufua fired up with and without the ball, owned the collisions, put the Rebels under pressure at scrum-time and overall were far smarter than a side placed second in the Australian conference and still with playoff pretensions.
The home side had no answer in particular to the power and pace of right wing Seta Tamanivalu, who scored the opening try and set up two in the second half – the latter to Pete Samu with a run from 50m during which he bumped off three would-be defenders.
Up front, starting hooker Andrew Makalio was an irresistible force scoring two tries and proving to be a valuable back-up to All Black Codie Taylor in the wake of Ben Funnell's injury last weekend. Tighthead prop Owen Franks was a monster in the front row for Robertson's men.
It was the Crusaders' sixth straight win but face far tougher challenges ahead. Next weekend they host the Waratahs in Christchurch but after that face only New Zealand teams; the Blues twice, Chiefs, Hurricanes and Highlanders in a run which will define their regular season.
