Damian McKenzie racked up 23 points as clinical Chiefs made a huge statement by hammering Brumbies 48-23 to end an eight-year wait for a victory in Canberra and return to the top of the overall Super Rugby standings.
Chiefs have now won four games in a row outside New Zealand for the first time in their history after running in six tries in a long-awaited victory over the Australian Conference leaders on Saturday.
Not since 2008 had Chiefs consigned Brumbies to a home defeat, but they set the record straight in style with a bonus-point triumph which puts them above Highlanders at the summit.
Brumbies, who had won eight of their last 10 home games against Chiefs, led 6-0 following two penalties from Christian Lealiifano in the first 10 minutes but Chiefs soon got into their stride.
Toni Pulu went over in the corner and James Lowe took a great offload from Aaron Cruden to touch down a few minutes after Matt Toomua had failed to find touch with a penalty
Scott Sio responded with his first try of the season and Lealiifano converted to reach the 700-point Super Rugby landmark, but Tom Sanders' try on the stroke of half-time and a second conversion from McKenzie put Chiefs 20-13 up at the break.
Two McKenzie penalties increased Chiefs' advantage and the visitors ran away with it after Scott Fardy's converted try had reduced the deficit to 26-20.
Lowe completed a double, then Brad Weber touched down soon after before the impressive McKenzie dotted down for consecutive game as Chiefs laid down a marker.
