Life member and past-president Graeme Bell, of Alexandra, presented the awards alongside senior vice-president Lane McSkimming and junior vice-president Janet Smith to Greg Stuart, Don Moffat, Allan Paterson, and John Nelson.
Mr Nelson first came as a helper to shearing shows in the late 1960s.
He started competing in shows before becoming a committee member in 1983, a role he had continued to the present day, Mr Bell said.
He enjoyed the shearing life, and since 1991 had carried out judging duties at the annual New Zealand Merino Shears event in Alexandra as well as other competitions in Otago and Southland.
Mr Paterson carried on a family tradition when he became a committee member and shearing referee and chief judge of the New Zealand Merino Shears.
"Shearers are totally professional these days," Mr Paterson said.
The family business, Armidale Merino Stud, had been a supporter of the society for many years, Mr Bell said.
Mr Stuart joined four generations of shearers when he began coming to the show as an 11-year-old.
He began competing in the mid-1980s and was now a judge.
Mr Stuart became a committee member in 1993 and was president in 2006 and 2007, with a second stint in 2019-21.
Mr Moffat had about 60 years of woolhandling under his belt and had been a loyal committee member since 1994, Mr Bell said.
Mr Moffat talked about how the "man from Dalgety" used to visit to explain woolhandling when he was at school.
For 26 years, Mr Moffat had been on the committee, including two terms as president in 2014 and 2015.
He had also been recognised by the Otago Shearing Society and the South Island Shearing and Woolhandling Society — being awarded a life membership of both.
"I’ve always enjoyed judging," Mr Moffat said.
