The Sea Eagles thumped Takuvaine Warriors 94-10 at the Happy Valley Field on Saturday.
The win puts the Muri-based club in the driving seat with 10 points from five matches.
The Sea Eagles have only the Arorangi Bears to play to complete the opening round of competition. The Bears who have lost only a match were on a bye over the weekend.
In the other premier matches, defending champions Tupapa Panthers defeated Aitutaki Sharks 50-20 on Friday.
The struggling Avatiu Eels lost again after going down to Titikaveka Bulldogs 12-14 at The Swamp on Saturday.
The win sees the Bulldogs go ahead of the Eels in fourth place.
“With one more game to play in round one, the undefeated Sea Eagles leads the pack on 10 points,” said Tai Nelio, the Cook Islands Rugby League competition coordinator.
“The Bulldog’s win against the Eels advanced them into the top four along with the Sea Eagles, Bears, and the Panthers.
“Round two looming up will start seeing some serious football with teams making a charge for a spot in the top four.”
Nelio was impressed with the turnout of supporters in the matches on Saturday.
