Rick Martini, son of an American airman incarcerated with Phil Lamason in Buchenwald Camp in 1944 but now a resident of New Zealand, was also present.
Rick recently wrote of his father's Buchenwald experiences and the consequences of that in his later life.
Peter Wheeler, from NZBCA, spoke about the legacy of RAF Bomber Command in the war and of the significance of the service of more than 6000 airmen from New Zealand in that force.
Almost 1800 of them perished in the course of duty.
Mr Wheeler highlighted how the emergence of individual stories of these Kiwis was now enabling people to have a deeper understanding and appreciation of that generation's commitment to the preservation of the freedom we often take for granted.
Mike Harold, chairman of the Phil Lamason Heritage Centre Trust, said Mr Lamason was a reluctant hero.
"He was a man of mana and he definitely ranks as a significant New Zealand figure of his time," he said.
"It is the goal of the trust to ensure his story is better known in his own country."
Writer Hilary Pedersen described the response so far to the book as "overwhelming", leaving her with a deep sense of pride, gratitude and humility.
She also acknowledged the superb work done by Sal Criscillo in the final presentation of the work.
Glenys Scott spoke compellingly of how she, as a close friend of Phil Lamason, was privileged to share his story.
"It was like Phil needed to 'unload' his story and each time we talked he added more and more to the detail," she said.
Son John Lamason spoke of the book as being an important history for their family for generations to come.
Together with daughter Christie, he then presented Mr Wheeler and Mr Morris with copies of the book for the Walsh Memorial Library at MOTAT.
Almost half of the initial print run of 800 books has sold and Mr Harold said the feedback had been very positive.
