Ferguson had been involved with the United Fire Brigade Association (UFBA) tech panel and had organised firefighting competitions both regionally and nationally.
He was due to attend the 2020 UFBA's South Island Firefighter Combat Challenge in Christchurch this weekend.
He was previously a long-serving member of the Luggate Volunteer Fire Brigade.
Deputy fire chief Matt Anderson said yesterday Ferguson served from April 1998 until January 2018, and was deputy chief fire officer at Luggate when he moved to Ranfurly.
Anderson said Ferguson was a valued member of the brigade who was "always there to offer his services".
"He loved going to all the meetings and was willing to do the business stuff that nobody else really wanted to do."
He was a self-employed builder and had built his own home in Luggate.
His wife Margaret died last year.
Maniototo ward district councillor Stu Duncan told the Otago Daily Times Ferguson was an integral member of the brigade.
Duncan understood Ferguson had been called out with the brigade to a crash the previous day.
"He was a lovely man and his heart was always with the community.
