Arrowtown and Wakatipu finished the round with convincing wins on Saturday and confirmed a tough battle between Arrowtown, Clyde, Wakatipu and Maniototo in the top four.
Playing away in Cromwell, Arrowtown thrashed the home side 62-5 with 10 tries shared among the backs and forwards.
Giant No 8 Ben Chisholm received player-of-the-day honours for Arrowtown after scoring a hat-trick of tries.
Coach Hayden Finch said Chisholm was a standout player not just for his try contribution, but in general play from the back of the scrum.
"Those tries weren't scored from five metres out, they were 22-metre kind of runs. He played well."
Finch said although the score reflected a hiding from the red and blues, the Cromwell boys gave them a "good battle in the forwards".
Tries went to Dylan Fletcher (2), Daniel Eyles, Kane Dodds, Josh Brazier, Matty Rapoama, Doug Kotouhi, with Fletcher converting six from seven chances.
The halftime score was 15-nil.
Finch said Arrowtown looked to be top of the table, one point ahead of Clyde - both sides have won six of seven matches.
Meanwhile, Wakatipu delivered a blow to Alexandra, 47-12, at the Wakatipu rugby grounds.
Wakatipu Captain Regan Pearce said the side was happy with the result considering Alexandra was known for "teaching others a lesson".
"It was a closer game than the score suggested.
"We played well and stuck to the game plan.
"We treated the game like a test match in some respects and went for the points."
Wakatipu started with a hiss and a roar scoring only five minutes in and taking the lead into halftime, 26-5.
Second grade fill-in from the Wanderers John Adair was given player of the day after a "standout" performance and could possibly have made his way into premier selection for next week's clash against Maniototo.
Coach Damian Petre said after his performance he would "certainly be playing for the next couple of games at least".
Pearce said the side had been selected to dominate the match up front and provide good ball for the back to send it through the backs quickly.
The side is keeping tactics quiet during the next week, as the heavily contested White Horse Cup is up for grabs in Ranfurly next weekend against Maniototo.
"I don't want to say too much about the game plan."
Maniototo had an unexpected loss to Clyde 42-11 on Saturday.
"The big concern for us is how Maniototo are going to react after losing, we will have a mighty battle on our hands."
Petre echoed the excitement and said the team would be looking forward to challenging for the cup as it had "been some time".
"It's the White Horse Cup and it's always a tough challenge.
"It's all pretty interesting now after round one, with Clyde, Arrowtown, Maniototo and us all in the running it'll be a good race to the finals," Pearce said.
Pearce had been told Clyde had taken the round one cup.
The Wakatipu Rugby Club gave 50-match blazers on Saturday.
Pearce was one of those honoured, along with Damian Petre and Damien O'Connell.
Wakatipu rugby legends B.C.
Douglas, Bill Dagg and Wattie Watson were presented with life memberships at the clubrooms.
