Hundreds took to higher ground to fill the Balclutha grandstand for a vantage point to watch the grandparade and then witness the crowning of the 2012 Show Queen.
Balclutha hairdresser Rachel Dick (19) won the coveted title, and was also named Miss Friendship and Miss Public Speaker.
Brian Gutsell, of Gore, returned again this year to compete in wood chopping.
Mr Gutsell has been taking part in woodchoppingcompetitions at various A and P shows for many years.
His relatives owned a sawmill in the Catlins and were involved in setting up woodchopping as a sport in New Zealand.
He now competes around the country, following in his grandparents' and uncles' footsteps.
South Otago A and P Society president Jim Berney said the show was one of the biggest events in South Otago's social calendar.
Mr Berney also praised Waitahuna farmer Symon Howard for his "exceptional sheep" which received several awards at the South Otago show, building on his recent success at the Canterbury A and P Show.
