"I think this could be a quite wonderful project, but we need the public's help," he said.
Ms Brown said while she was busy putting together volume four of Rotorua Retro, she was happy to help preserve Rotorua's wartime memories.
"We are looking for the smaller stories about particular incidents or events that stick in people's minds - not the 'I went to war on such and such a date' - sort of thing.
"They could be from the veterans themselves, their family or friends as well."
Ms Brown said she had a small team of writers available to help interview and record people's stories, or people could write and submit them themselves.
She said more volunteers to help with interviews and writing would be appreciated.
They said the aim was to have the book ready for publication by the 100th anniversary of the end of World War I on November 11, 2018.
It would also coincide with the Rotorua World War I Committee's plan to hold an Armistice Day ball.
