Last year's losing ITM Cup finalists Waikato got their revenge by beating defending champions Canterbury 27-13 at Rugby Park in in Christchurch on Wednesday.
Waikato's bonus-point win enabled them to leapfrog Canterbury into third place on the Premiership table, as the red-and-blacks slumped to their third win from four games in the top tier.
All Blacks centre Richard Kahui, returning from a hamstring injury, got on the try-scoring sheet as Waikato deservedly disposed of their Southern rivals after Canterbury ran over the Mooloos in last year's final.
Waikato had the four-try bonus point after just 25 minutes when Kahui crossed over after a thrilling 75m counter-attack and the Mooloos led 24-10 at the break after an entertaining first half.
But the second spell produced only a penalty apiece and deteriorated so much that the final whistle came as a relief to the crowd of 3,500.
