Mrs Johnsen said the experience was inspirational, and she and her husband had enjoyed mixing with the other entrants.
"We met some awesome people," she said.
The judges were impressed with their operation, awarding them category wins including the LIC Dairy Farm Award, which recognises the important role that herd improvement plays in a sustainable farming business.
They also praised their best-standard record-keeping and comprehensive health records.
"Herd reproductive performance is excellent, and the herd BW is in the top 10 per cent nationally," they said.
The couple said the Dairy Farm Award had been welcome recognition of the hard work they had put into their herd genetics.
They were in the process of changing to a crossbred herd, which they believed was benefiting the farm and increasing profitability."
They took great pride in the health of their herd, because "happy cows equal happy farmers."
And they encouraged other farmers to enter the awards, "because there is always something to learn and improve on the farm."
