Owner Chris Brown said it was the first time the butchery had received a medal in the bacon category.
In previous years, the butchery has won an array of awards including supreme, gold, silver and bronze.
"Every bacon and ham product we produce is an award-winning product and we have awards in every bacon and ham category," Mr Brown said.
Mr Brown, who has been a butcher for more than 30 years, and his wife Sue took over the butchery in 2006.
Before then, Mr Brown who describes himself as a "passionate cook", had done a lot of commercial cooking in Christchurch, while Mrs Brown had run several Robert Harris cafe businesses.
Mr Brown said there was something about the Ellesmere Butchery that just "grabbed him" when it first came up for sale.
The family took a risk by buying the butchery, and Mr and Mrs Brown moved with their children into the Leeston area.
At the end of 2015, the shop was put on the market, but the Browns could not find the right people to take over the business.
"I don't want the skills I have built up to go to waste. I want to pass that on . . . hopefully, the legacy of this shop continues," he said.
Until they find the right people, the Browns will continue to run the butchery.
As for the next competition, if the opportunity arises, Mr Brown hopes to take up the role of being a judge.
'It would be so good to see what the other butchers are doing," he said.
