The Crusaders will get a gift four points for a bye this week, while the Blues travel to Cape Town where they will tangle with the unbeaten Stormers. The Hurricanes have been the emerging surprise with two wins, but those victories came against the Lions then the Force who were dreadful in the last round.
This week, the Hurricanes will face their first challenge from a conference rival when they host the unbeaten Highlanders.
The southern side have begun the series with a relish and resistance which did not show through in any of their pre-season trial matches. None of their victories has been dominant - a four-point margin against the Chiefs, three against the Crusaders and a solitary point against the Waratahs - but they are leading the conference.
Captain Jamie Mackintosh fingered superior fitness as the backbone for his side's success.
"It is a great start. I didn't think we would be three from three, but I guess we can think about rotating players now," he said.
The latest 18-17 win against the Waratahs came despite another weird final flourish. Last week the Highlanders kicked the ball out several times when they confused the final arbiter as the ground clock instead of the referee.
This time, replacement halfback Jimmy Cowan bizarrely tried to hack the ball out to the longest touchline after the siren sounded, and came up well short, forcing his teammates to scramble the ball to safety.
Most rugby observers felt the Chiefs would struggle when they lost senior props Ben Afeaki and Toby Smith to lengthy injuries in round one.
It was a theme picked up by coach Dave Rennie.. "We had a lot of belief in our camp that we had a pack to compete," he said.
That conviction has proved solid so far and about as unyielding as the 138kg Ben Tameifuna on the tighthead side of the scrum and the irrepressible Sona Taumalolo on the other.
The twin Hawkes Bay pillars went home on Friday and, with their colleagues, messed up the Crusaders' test frontrow.
Forwards coach Tom Coventry has the pack in scrumming harmony which is rugby music for a franchise with scant Super rugby pedigree up front.
The Highlanders and Chiefs have weathered tough schedules to start the competition and may find some relief this round with encounters against the Hurricanes and Brumbies.
But they cannot drop their standards or allow their attitude to wander otherwise they will struggle as the champion Reds did against the lowly Rebels.
