Trainer Terry Kennedy starred on his home club's biggest day, scoring a winning treble with Ray's In Command, Bakela and Havana Heights.
Trainers Brian and Shane Anderton notched wins with Gallant Boy and Outram, and Steven Prince's added a victory with Deciptio Visus.
Wingatui jockeys Jacob Lowry, Courtney Barnes and Corey Campbell notched a victory each on the Wingatui runners.
Barnes rode Havana Heights to win race 5. Her
United Kingdom owner David King enjoyed instant success with Kennedy when the 5yr-old gained her maiden win over 1400m.
King offered Kennedy the mare to train as Kennedy had had success training her half-sister, Lesley Brook, to win five races.
"David rang me out of the blue and asked me if I would train the horse for him because she was a half-sister to Lesley Brook," Kennedy said.
Havana Heights had largely struggled in the North Island before joining Kennedy, with two placings in 12 starts.
The mare looks as if she will improve on her record, judging by the way she ran to the line yesterday. Havana Heights pricked her ears halfway down the straight and looked more focused on the action on the outside of the track than the race in front of her.
"I think she will do a good job down here. She has still got a bit to learn," Kennedy said.
"She is bred to get a bit of ground, probably not this season, but next season she could be a Dunedin Gold Cup horse because she is a beautifully bred mare."
Bakela relished stepping on to an improved track to win race 2, after battling through heavy ground in his recent starts.
Rider Chris Johnson gave Bakela the perfect run behind the leader, Bluey's Chance, before the 5yr-old overhauled his rival in the straight.
Johnson produced a brilliant ride to score the first of his two wins for Kennedy with Ray's In Command in the opening race.
He set a comfortable race tempo for the 5yr-old before letting him sprint to a comfortable maiden victory
"It was a great ride by Chris. He said the horse won with plenty in hand and gave him a good feel," Kennedy said.
Members could be forgiven for thinking Ray's In Command is named after Otago Racing Club president Ray Kean.
The galloper is raced by the club's former president, Stephen Grant, and fellow committee member Fred King.
King formerly raced and still owns Lesley Brook, the half-sister to Havana Heights.
He is no relation to Havana Heights' owner, David King.
Kean took over the presidency of the club from Grant last year.
Grant said it was merely a coincidence that Ray's In Command shared the name of the man now in command of the club.
"We raced the dam, Kay's In Command, and Ray's In Command is a combination of her name and his sire, Raise The Flag."
Kean also notched a win yesterday, as he shares in the ownership of Outram. The 4yr-old won race 7 over 1200m with Jacob Lowry in the saddle.
