The Balmacewen golfers retained the title after qualifying for the final by winning the metropolitan senior A series earlier this year.
Scoring was good, considering the conditions, which were clearly illustrated when Otago captain Brandon Hodgson required a two iron to reach the 122m par 3 third into the wind and hit a five iron 250m downwind a couple of holes later.
Otago beat Lower Waitaki by 5 to with junior Scott Clark holding the well performed Daniel Elder to a half for the Oamaru club's half game.
The Balmacewen golfers won two matches and halved one another in the afternoon to beat Arrowtown by 4 to 1.
As there was no team from the South Otago sub association, the event was played as a triangular between Otago (metropolitan), Arrowtown (Central Otago) and Lower Waitaki (North Otago).
This meant only half of each six man team played each opposition in the morning and played the other half in the afternoon to complete each contest.
The Balmacewen golfers had the edge at lunch, leading Lower Waitaki 3 to nil and a 2 to 1 lead over Arrowtown.
Lower Waitaki looked set for second place, posting two wins and a loss in its morning match against Arrowtown.
Otago No6 Harry Smith brought Lower Waitaki's chances to an early end when he notched his team's fourth win with a resounding 8 and 6 over Harrison Maaka in the afternoon.
Brandon Hodgson, Nick Borren Tyrone Ratahi and Harry Smith won their two games for Otago, while Ben Patson emerged unbeaten with a win in the morning and a half with Arrowtown's Ben Hamilton in the afternoon.
Arrowtown No3 Chris Yallop was the only other player to win both matches. Scott Clark (Lower Waitaki) had a win and a half.
