They were competing at the annual New Zealand blind and partially sighted indoor bowls championships.
Nooapii Rouvi (55) regained the men's singles trophy and Doreen Wintrup was named the most successful coach.
It was Nooapii's second national singles title.
He also won in 2009.
He also plays interclub indoor bowls with sighted players at the Kew Club.
Tangi Rouvi (50), his sister, was a member of the fours team that won the plate section. She was an accurate lead and the other members of the team were Lyn Keogh (60), Janice Wilson (44) and skip Janice Fleming (44).
Tangi, who is coached by her daughter Lisa, first made her mark on the national scene in 2002 when she won the national championships singles and the champion of champions singles.
Wilson qualified for post-section play in the partially sighted singles section.
Wintrup has been involved with blind and partially sighted indoor bowls for 13 years and was also named the top coach in 2009.
There are 17 members in the Otago Blind Indoor Bowls Club and five travelled to Hamilton for the championships. There were 100 competitors from 11 regions competing in Hamilton.
"It was Otago's best performance at a national championships," Wintrup said. "We are proud of our team."
In the pairs and fours, totally blind and partially sighted players combine to play against each other.
But it is different in the singles with a section for the totally blind players and another one for partially sighted players.
The players use standard indoor bowls, but are allowed to be guided by their coaches.
