Kaino, who has returned to New Zealand after two seasons in Japan and was one of the players of the 2011 World Cup, made several storming runs and bone-crunching tackles for the Blues, who scored tries to Lolagi Visinia and Francis Saili while flyhalf Simon Hickey added 11 points with the boot.
Waratahs loose forward Jacques Potgieter's impressive physical performance was rewarded with a try, while flyhalf Bernard Foley added a conversion and two penalties.
The Waratahs' impressive attacking axis of Foley, inside centre Kurtley Beale and fullback Israel Folau, was snuffed out by the Blues' defence, while the visitors also made too many handling errors at crucial times.
The ACT Brumbies scored 15 points when Waikato Chiefs replacement winger James Lowe was sinbinned in the second half to avenge their loss in the final last year with a 41-23 victory in their Super Rugby clash in Canberra.
Lowe was given a yellow card for foot-tripping Brumbies winger Joe Tomane and the home side capitalised with two tries to centre Tevita Kuridrani and a penalty and conversion to scrumhalf Nic White to blow their lead out to 33-9.
Tomane and flyhalf Matt Toomua scored earlier tries for the home side, who moved to 30 points and extended their lead in the Australian conference after the New South Wales Waratahs (24) were beaten by the Auckland Blues earlier on Friday.
The Chiefs had been in the game at 13-9 down shortly after halftime when Gareth Anscombe slotted his third penalty before the yellow card and saved face with late tries to replacement scrumhalf Brad Weber and prop Josh Hohneck, though Toomua's second try after the final hooter rubbed salt into their wound.
