The Hurricanes put on an attacking masterclass to dispose of the Waratahs with a 41-29 victory at the Westpac Stadium to register their fourth win of the season.
Julian Savea led the way with two tries, while Reggie Goodes and Motu Matu'u both touched down. The boot of Beauden Barrett added 21 points - the equal highest points tally by anyone this season - thanks to three conversions and five penalties.
Bernard Foley, Adam Ashley-Cooper and Aussie Rules convert Israel Folau all scored tries for the visitors, who were boosted by a conversion and four penalties from half-back Brendan McKibbin.
Winger Jason Woodward scored two tries to help Melbourne Rebels to what could be a vital 30-23 win at Western Force.
Rebels were on a five-match losing run, but a spirited display at the Perth Oval brought an end to that streak and gave them their second win of the season.
Missed kicks from Sias Ebersohn and Kyle Godwin cost the home side dearly, as their poor form in the competition continued - Force have won just one of their opening seven matches.
The Cheetahs came from behind to snatch an extra-time 26-24 win over the Stormers and extend their winning streak to five.
