Oyster connoisseurs from around the world converged on the Bluff Oyster and Food Festival to consume the delicacy on Saturday.
Whether they were au naturel, succulent and juicy, dressed in batter, Kilpatrick or a variety of other ways, more than 20,000 oysters were consumed, Bluff promotions officer Lindsay Beer said.
An estimated 4500 people flocked to enjoy the food and be entertained by music and oyster-opening and oyster-eating races.
Mr Beer said 75% of patrons came from outside Southland, some from as far away as Australia, South Africa, the United Kingdom and China.
Two charter flights from Auckland and one from Wellington transported about 450 people to Invercargill before they were bussed to the festival and other attractions in the area, including Transport World and Invercargill Brewery.
