"I've written about these men, how their life was growing up, their formative experiences in the Bay of Plenty, how they were called up and then of course their journey through the campaigns of World War II," he said.
"In the book I've written about B company, which covers Taupo, Rotorua, Whakatane, Opotiki etc and 850-900 men from here signed up."
Sir Harawira said he wanted to include a roll call in the back of the book, with a photograph of each of the men who served in the unit.
"Rotorua Museum has been able to provide me with photographs of 500 men, but I'm still tracking down 400, so now I am asking the families for help," he said.
"I'll do whatever I have to do to get the photographs, I will travel to the families, I will jump out of a plane. It's a big job."
Leanne Tamaki, spokeswoman for the Ministry of Culture and Heritage, said the project was sponsored by the B Company Trust.
Trust chairman Graeme Vercoe said it was an appeal to "the B company community".
"It's supposed to be a legacy publication and really we should have done it years ago," he said.
"Unfortunately it never got done, but it's never too late."
Mr Vercoe said this was the first opportunity they had to engage with the men's whanau.
"To encourage them to share their photographs, their stories."
