The bonus point victory pushed the Hurricanes (7-2) to the top of the ladder and left the Brumbies (5-5) in danger of slipping to sixth, after the Crusaders had jumped them into fourth on Friday thanks to a bonus-point win against the NSW Waratahs.
It was the Brumbies' first loss to New Zealand opposition in five games this season. But two losses to Fijian Drua - as well as defeats against the NSW Waratahs and Queensland Reds in Canberra - have undone that good work.
New Zealand sides now occupy the top four spots on the ladder, after the Blues escaped with a 36-33 golden-point defeat of the Reds in Saturday's late game.
Hurricanes winger Fehi Fineanganofo (four tries) ran rampant against the Brumbies, notching a first-half hat-trick thanks to quick feet and slick hands in a Ruben Love-led backline.
"Do you want to chip in? It'd be nice to keep him here," Hurricanes coach Clark Laidlaw said of Fineanganofo, who has signed with Newcastle in England for next season.
"Forget higher honours, for us he's genuine x-factor ... he might be back, he's only 23."
The Brumbies were dealt a blow before kick-off, with talisman prop Allan Alaalatoa ruled out of the game and next week's clash with the Reds due to concussion.
And it got no better for Stephen Larkham's men in the first of two Anzac Day clashes at Christchurch's sold-out One NZ Stadium.
Twice in the first 40 minutes, flyhalf Declan Meredith kicked the ball dead in goal attempting to find touch after winning a penalty.
He was not alone though. Tom Wright struggled with his in-game kicking while Ryan Lonergan and Andy Muirhead both pushed kicks dead to kill any momentum.
Some poor defence and line-out execution also hurt the side, Fineanganofo's third, after back-to-back Brumbies knock-ons making it 19-0 at halftime.
Larkham replaced prop James Slipper with Blake Schoupp at halftime while Tane Edmed relieved Meredith.
They had some joy, with Corey Toole's flick pass as he went into touch finding David Feliuai for a Brumbies try.
But the Hurricanes hit right back, the ball kept alive before winger Josh Moorby crashed over for the first of his two tries.
Fineanganofo was able to play to the crowd before jotting down his fourth try, beating Edmed to a loose ball after two Brumbies passes completely missed their mark.
Brumbies replacement Toby MacPherson was denied a try on review before Toole got one back with an intercept, runaway effort with 10 minutes to go.
But the Hurricanes replied with two more tries of their own to complete the rout.
"It's disappointing to come over here with big expectations, big support come over," Larkham said, lamenting their kicking and line-out woes.
"He (Meredith) takes a lot of responsibility for the outcome of that game, on the back of those two kicks. Big moments of the game ... (but we'll) move on from this game as quickly as possible."
