Clutha Valley Volunteer Fire Brigade chief fire officer Richard Hunter said his crew were in shock after attending the accident on Clutha Valley Rd in the early hours of Saturday.
Police confirmed one person died after emergency services were called to a single vehicle crash around 1.55am Saturday.
The driver was the sole occupant of the vehicle, which went off the road between Craig Rd and Allangrange Rd.
The tragic death comes just 14 months after the brigade lost Blair Halder, 41.
Mr Hunter said his crew were still talking about the loss of Mr Halder, and were struggling to process a second blow so soon.
"He was a great guy, very passionate for life, for his family, for the brigade. He loved his family, and we can’t express to them how sorry we are for this massive loss."
He said Fire & Emergency NZ was helping the brigade address the tragedy.
"FENZ are great at wrapping round [the team]. It’s been less than 48 hours really, so we’re all still processing."
Farmer and volunteer firefighter Blair Halder died following a tractor accident on a Kononi property in April last year.
At the time, Mr Hunter described him as a "genuinely good guy" who had his community at heart.
Mr Halder was a volunteer firefighter for about 23 years, serving first in Dipton then, from 2015, in Clutha Valley, where he was brigade secretary.
The latest tragedy comes just two months after the brigade celebrated its 50th jubilee.
