The Crusaders extended their winning streak to four matches when they hammered the Brumbies 40-20 in Christchurch on Saturday.
The victory was also the fourth in a row for the Crusaders over the Brumbies and provisionally moves them to the top of the New Zealand Super Rugby conference.
The Crusaders lost three of their first five matches including two at home but have now recovered and are unbeaten since the end of March when they lost to the Hurricanes at home in Christchurch.
The Crusaders victory was built around their dominant forward pack.
Penalties flowed as the Crusaders' physicality humbled the leading Australian side allowing fly-half Colin Slade to land seven penalties in a match where tries were scarce.
The scoreboard was driven solely by penalties for the first 40 minutes until Johnny McNicholl broke the drought at the end of a long Crusaders build up to score on the stroke of half-time.
Stephen Moore responded for the Brumbies immediately after the resumption, before Nemani Nadolo and Luke Whitelock came back with tries for the Crusaders and Pat McCabe scored for the Brumbies in the closing stages.
Although the Brumbies enjoyed the greater possession and territory they lost two of their own lineouts as well as three scrums and the turnovers went in the Crusaders favour 6-2.
A central figure in the Crusaders' forward control was All Blacks Test centurion Richie McCaw who was instrumental in securing several turnovers in his first game back after breaking a thumb in the second round.
"To come out and create the quick ball that we did allowed us to really play," said Crusaders captain Ryan Crotty.
"We knew we had to upset (their forwards) if we were going to be a chance. Their lineout is one of the best in the comp, and their scrum as well, so big ups to our tight five, they really fronted."
The Crusaders led 22-6 at half-time after Slade had landed five penalties and converted McNicholl's try while the Brumbies were forced to rely on two penalties to Nic White.
Moore's try converted by Christian Lealiifano immediately after the resumption narrowed the gap to 22-13 before the Crusaders powered away.
Slade added two further penalties and Sam Whitelock charged down a White kick that bounced into the arms of Nemani Nadolo who had a clear 40-metre run to the line.
The final Crusaders try came from a lineout steal by Luke Whitelock who was on hand to finish off the move on the opposite side of the field.
As the game loosened up with the Crusaders looking for a bonus point try it was the Brumbies who had the final say when McCabe found a way through the Crusaders defence.
The Crusaders have now won six of nine games and moved to the head of the tightly packed New Zealand conference although three sides, including the defending champion Chiefs, are still to play this weekend.
The Brumbies remain at the top of the Australian conference with seven wins from 10 matches.
