The Chiefs have returned to their title-winning form in Super Rugby after overwhelming the Cheetahs 45-3 at Waikato Stadium on Saturday.
With their title defence under question after last week's 41-27 win over the Highlanders, the champions showed a defensive performance showcasing why they secured their maiden title last year.
Chiefs fly-half Gareth Anscombe's accurate start to the 2013 season continued as he scored a try, kicked six conversions as well as a penalty for a personal tally of 20 points.
Liam Messam, Ben Afeaki, Asaeli Tikoirotuma, Rhys Marshall and Ben Tameifuna also crossed for Chiefs.
The Bulls also made it two victories from two at the start of the new season after coming from behind to beat winless Western Force 36-26 in Pretoria.
The Bulls, champions in 2007, 09 and 10, saw off South African rivals the Stormers 25-17 in their opening match but looked in danger of defeat after finding themselves 26-19 down with 11 minutes to go at Loftus Versfeld.
However, converted tries from Jean Cook and Juandre Krugar, plus a penalty from Morne Steyn, in the closing stages saw the hosts over the winning line, earning a bonus point in the process.
Steyn finished with a try, four penalties and two conversions for a personal haul of 21 points, while Sampie Mastriet also crossed for the Bulls.
Sharks continued their winning start to the new campaign with a 12-6 victory over South African rivals the Stormers in Durban.
All the points came during an 18-minute spell at the start of the second half at Kings Park Stadium, with Sharks fly-half Patrick Lambie outscoring Stormers full-back Joe Pietersen four penalties to two.
