Clutha Valley Volunteer Fire Brigade Chief Fire Officer Richard Hunter said his crew were in shock after attending the accident in Clutha Valley Rd early on Saturday.
Volunteer firefighter Logan Sinclair died in the crash.
Police confirmed Mr Sinclair died in a single-vehicle crash about 1.55am on Saturday.
The death comes just 14 months after the brigade lost Blair Halder, 41, following a tractor accident on a Kononi property.
Mr Hunter said his crew were still talking about the loss of Mr Halder, and were struggling to process a second tragedy.
He said Mr Sinclair was a ‘‘great guy’’.
‘‘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 and Emergency New Zealand 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.’’
The latest tragedy comes just two months after the brigade celebrated its 50th jubilee.
