"It's an important time in our town's history and I'm hoping families may have kept alive stories from 100 years ago which could be used as part of our commemoration," Nancy Wadsworth, president of the Dannevirke Gallery of History, said.
"While we have reports from the Dannevirke Evening News, I think there must be stories which have been shared about that terrible time which could add a richness to our display."
The fire caught most residents and firefighters off-guard and, unfortunately, fire brigade members soon discovered they were up against something their gear and apparatus could not cope with, and shop after shop was lost.
Firefighters from Dannevirke were joined by others from Woodville and Waipukurau and eventually the wind dropped, helping them gain control.
There were losses of about £250,000 for the buildings that were destroyed, with fire-insurance cover of just £77,000.
