All seven winners on the day had a connection to the province, either being trained or owned in Otago, or ridden by a jockey based at Wingatui.
At the forefront was apprentice jockey Courtney Barnes, who had her best day to date in her career, saluting on three winners - Include, Jacksanfives and Split Decision.
She was only a neck and half a neck off picking up five winners for the day, with She's Insatiable and The Glitzy One just missing out in their respective events.
Barnes kicked off the day with Include, an impressive winner on debut.
The 3yr-old Gallant Guru filly hauled in Ravishing in the final 100m quite comfortably in the 1200m maiden, and the manner of her win had co-trainer Brian Anderton considering a late nomination for the 1000 Guineas in Riccarton in November.
''We'll see what happens between times. We can always pay a late entry fee if we want to,'' Anderton said.
The filly is owned by White Robe Lodge stud managers Wayne and Karen Stewart, who bought Include's dam, She's Snubbed (by O'Reilly), at the 2007 mixed bloodstock sale at Karaka.
The Waikato Stud-bred mare has also left Immortal Glory (two Australian wins) and 2010 South Island Breeders Stakes winner Sharp Princess.
''The full brother [Immortal Glory] won two out of six runs in Australia,'' Anderton said.
The Stewarts will breed She's Snubbed to Raise The Flag in the coming days. Raise The Flag served the recently-retired Inferno on Friday, and stakes winner Miss Millbrook on September 21.
Barnes' second winner, Jacksanfives, benefited from the addition of blinkers for the first time in four starts, trainer Terry Kennedy said.
''The blinkers probably helped and made her concentrate a bit more,'' Kennedy said.
Kennedy may look at a run in the coming weeks, or the 7yr-old mare might find herself taking a break.
''We might even go out and come back in again,'' Kennedy said.
After Wingatui-Westwood Beach trainer Amber Hoffman won the third event, Riverton trainer Kelvin Tyler spoiled the run of Otago-trained winners with Indy Ruler's deserved win in the rating 65 1600m.
However, the 5yr-old gelding is owned by Ken and Diana Bonham in Queenstown, to ensure the local links continued.
''I trained the full sister to him [Provence] and she was a really good horse who had a few injury problems,'' Tyler said.
''I was just a bit wary whether race condition would just give out in the last bit but he's a genuine horse.''
Split Decision continues to provide a pick-me-up for Tapanui trainers Nikki and Barrie Blatch following a fire which destroyed their stables prior to the mare's win at Winton last week. Her win in the $15,000 Balclutha Cup is her second from two starts in this campaign.
''It's quite timely to get a wee win after that,'' Barrie Blatch said.
The daughter of Savabeel is in career-best form, winning three of her past four starts after battling for much of her 41 starts prior to Saturday.
''She's going awesome. Maybe a bit of age [helped].''
Blatch is happy to stay around the deep south rather than head up the highway to Riccarton.
''Plans could change, but there are some nice enough $10,000 to $15,000 races down here, with the cups and bits and pieces.''
Wingatui jockey Toni Direen guided home On The Take in the rating 85 1400m before Doni Prastiyou worked hard to get Anzac Star home after 14 months off the scene through injury.
''It's very satisfying,'' Wingatui trainer Paul Richards said.
Richards had plenty of praise for Prastiyou's ride against a strong sprint field.
''It was perfect. I said to him: `There's a bit of speed in the race. If they want to lead, let them and just sit on them and have the last say at them'.
''He's not really a Riccarton horse. There's plenty coming up so we'll find a race for him.''
Apprentice jockey Rowena Smyth was suspended for four days after admitting to a charge of careless riding at Te Aroha on Friday.
Smyth angled her mount Mrs Browns Boys in abruptly with 1350m to go in a 1400m maiden, forcing I Gotta Hunch in to the line of Trapped Again, which was checked and lost ground.
Smyth's suspension starts on Thursday and she is free to ride again on October 7.
