The Blues ran in five tries to score a convincing 44-14 victory over the Reds in Auckland on Friday.
The result was never in doubt, with the hosts running up a 34-0 lead before the Reds added some respectability to the scoreline with two second-half tries.
Most of the damage was done during a 10-minute period following James Slipper's yellow card for a tip tackle on Frank Halai.
It was another timid performance from the Reds, who didn't manage one clean break throughout the game.
Ma'a Nonu shone once again for the Blues, having a hand in each of the Blues first three tries, while Simon Hickey contributed 17 points from the boot in a flawless kicking performance.
The Blues must be considered play-off contenders now, with the win moving them above the Chiefs. Meanwhile, the Reds remain rooted to the foot of the Australian conference.
