The ace junior driver equalled his best tally for a meeting. He drove six winners on a seven-race card at Forbury Park in July, 2009. He drove five winners and a second on a six-race card at Oamaru on March 15.
Dunn (21) had two further wins at Washdyke yesterday. He is leading the premiership with 183 wins. He has about two months to surpass his record tally of 204 wins set in the 2008-09 season before leaving to drive in the world championship in New York.
He is keen to make the trip before the series commences to gain experience in America.
Dunn included the $25,000 Southern Country Cups Final with Flying Diamonds among his wins on Saturday. His other winners were Maori Invasion, Pattisun, JB Maguire, Dream Out Loud and Anvils Top Gun.
He also had a second with Kristina in the Southland Oaks, a second with Monaghan and fifth with Omega Jaccka from nine drives. He amassed $59,768 of the $182,500 stakes offered.
Flying Diamonds is raced by breeders Kevin Fairbairn, of Dacre and John Duff, of Longbush and trained by Tony Stratford.
The Oaks was won by Jumpforjoy, trained and driven by Clark Barron, who races her with Alex McDonald, of Makarewa. They bred Jumpforjoy from Joyfulbelle, who is also the dam of Joyfuljoy (11 wins).
McDonald bred and raced the 1993 Southland Oaks winner Lento, trained and driven by Henry Skinner. Barron drove Zitura, trained by his brother, Ken, to win the race in 2006.
Jumpforjoy had been out of work for three weeks since her previous race in Auckland on March 4 after keyhole surgery to remove three bone chips from a hock.
"Brendon Bell did the operation and his advice has been important in bringing her back," Barron said.
Jumpforjoy has won six of her 11 starts and placed in four others for $67,495 in stakes.
Jumpforjoy led over the last 1200m of the 2200m and held on by a neck from Kristina.
Jumpforjoy has the Sires' Stakes Final, New Zealand Oaks and Harness Jewels on her programme over the next month.
Olivia and Adam Carville have had a dream start as owners. They were given a share on Ohoka Texas by their mother, Katie, two months ago and the colt won the $40,000 Southern Supremacy Stakes Final on Saturday.
Katie had raced Ohoka Texas with her husband, Dave, who died in September.
Ohoka Texas was the only drive on Saturday for David Butt, who was resuming after five weeks on the sideline with a fractured collarbone.
He took Ohoka Texas to the front after 700m of the 2700m.
Ohoka Texas won by a length from stablemate Malak Uswaad, who led out, then trailed.
A Harness Jewels start was decided for Ohoka Texas after discussion between Butt and Katie Carville. It was not Butt's preference.
"I am not sure a mile is his go.
"I would have liked to put him out for a couple of months spell," Butt said.
