The absence of Titikaveka Bulls which failed to turn up for the opening rounds of matches marred the competition fixtures.
Takuvaine Reds and Tupapa Panthers had to play a match each against each other which the Reds won 5-0.
They won their matches against the Bulls via default.
Tournament favourites Avatiu Nikao Eels made a losing start after going down to an in-form-looking Yalovata 12-14 in their opening match.
The side bounced back to thrash Vikings from Arorangi 34-0 to keep their chances of winning the title alive.
Vikings lost the other match to Yalovata 14-17.
Vikings and Yalovata are dominated by Fijians residing in Rarotonga. The teams also have other foreign players plying their trade here.
Cook Islands Rugby Union chief executive officer Ben Koteka acknowledged the slow start to the Sevens series, which will run over four weeks.
However, he is hoping the momentum will pick up this weekend when the finals of the first of the two tournaments will be held.
“The best players for the day were Tua Ravula for the Eels who scored four tries. Pao, who played for Ngatangiia this season and featured for the Eels on Saturday also did well,” Koteka said.
