The 21-year-old defeated Phil Urlich of Mauke Bowling Club to claim the top spot in the fiercely competed event.
Third place went to Arorangi Bowling Club’s Lawrence Paniani.
In the women’s competition, Tai Tangi Jim of Rakahanga Bowling Club claimed the top spot, followed by Rarotonga’s Tai Tou in the second place.
Third place for the women went to 16-year-old Tiari Tangi Jim of Rakahanga.
Bowls Cook Islands’ Ben Mose was pleased with the youngsters’ performance and is expecting similar competition in the men’s and women’s pairs events, which will run until this Saturday.
Paniani, who is combining with fellow Commonwealth Games bronze medallist Aidan Zittersteijn, are the favourites in the men’s pairs competition.
The duo created history at the Gold Coast Games in April this year by winning the Cook Islands’ first-ever Commonwealth medal.
“We haven’t had a lot of time together to prepare for this weekend, but no doubt we will just pick up where we left off in the Gold Coast,” Paniani earlier told this newspaper.
“Having a bit of a profile now will probably mean the other teams will be gunning for us, but it will be a nice measure of where we are at and what we can focus on.”
Taranaki-based Zittersteijn, who is in Rarotonga to take part in the competition, is also hoping for some downtime to catch up with family and friends.
