A number of smaller events will be held as part of Hamilton's Sheepvention in 2021.
The Hamilton Pastoral and Agricultural Society decided to introduce a new format due to COVID-19 restrictions.
President Kathryn Robertson said the restrictions meant it wouldn't be possible to hold the event the way it had in past years.
"The committee have decided to reformat the structure and produce multiple, smaller events," Ms Robertson said.
"The current proposed events will be a sheep focused event in August and a broader ag event in October."
Ms Robertson said the August event would be a ram sale and trade exhibition, while the October event was expected to include trade exhibitions and machinery demonstrations.
"The reason we have decided to run more than one event is due to number restrictions and density limits in place because of COVID," she said.
"We hope to look at more events including some of our agricultural competitions and shows and something for our general indoor and food and wine traders later in the year.
"We had to find combinations of our Sheepvention product that would work together and could fit within our existing buildings so we weren't risking the outlay for marquees."
A prospectus outline details will be released next week.
Ms Robertson said the committee would return to the original event format as soon as it could.
"We are excited to be offering something different this year via a portfolio of events," she said.
"We welcome your support while we navigate this new challenge."
