Society president Brian Thomson said the requirements of the Covid-19 traffic light system meant the show had to be restricted to a horse event, the "paddock to plate" event and wool judging.
"We have good numbers of entries for the horse event, which will be run in two bubbles of 100 competitors," Mr Thomson said.
"And there have been outstanding entries for the paddock to plate competition."
The events, along with the wool judging, would be held at the Otago Taieri A&P Showgrounds in Mosgiel, as usual, and anyone entering the site would be required to have a vaccine pass.
"Unfortunately, we can’t open the event to the public, only to competitors," Mr Thomson said.
"As a committee, we are sad that the public are not able to join us this year — the A&P show is usually a great day out for the people," he said.
The society would adopt a wait-and-see approach for the remainder of this year in terms of the pandemic, and hoped to be able to return to a full A&P show next year, he said.
