Vainikolo was invited to train with the Bay men's sevens team this season after catching the eye of one of the coaches during an under-19 tournament. He also played at the 50,000-seat Aloha Stadium in Hawaii during an indigenous sevens tournament last year, helping a team from Hamilton win that competition.
"It's been a good experience playing with the older boys and playing senior sevens rugby. It's so much tougher and everyone has more experience than secondary schools."
Bay of Plenty men's sevens coach Peter Woods has used Vainikolo during his team's last two big tournaments, including the Bay Engineer Supplies Provincial Sevens tournament held at Mount Maunganui last weekend.
Following that tournament, Woods said he had some tough decisions to make ahead of naming his final 12-man team this week.
"As a coach you want a bit of a headache when it comes to selection with two or three guys fighting for one position."
Woods said he hoped to finalise his 12-man team tomorrow evening but was waiting on the fitness of a couple of his players. Two players are still to be cleared from ankle sprains suffered in Mount Maunganui at the weekend " Rewita Biddle and Ngatai Kingi.
Fortunately, captain Matt Axtens will almost certainly be okay for this weekend's tournament, following a cut near his eye, and Zar Lawrence is also hoping to recover in time following an Achilles problem.
The Bay of Plenty women's sevens team failed to qualify for nationals during their qualifying event in December.
