A veteran New Zealand journalist, David Robie, is to launch a new edition of his book on the bombed Greenpeace vessel, the Rainbow Warrior, next month.
Mr Robie sailed on the sabotaged ship for 11 weeks before French agents sank it in Auckland.
He says the new edition of "Eyes of Fire: The Last Voyage of the Rainbow Warrior" will include new material.
Mr Robie says with the 20th anniversary of the bombing approaching, a lot of attention will be given to the French spy drama.
However, he says the real story for him was the plight of the Rongelap islanders in the Marshall Islands and their suffering from the legacy of American nuclear tests in the 1950s.
"I owe it to the people of Rongelap to tell their story again, at a time when there is probably going to be a lot of concentration on the spy drama and this book particularly concentrates on the plight of islanders who have been affected by radiation over the years. So it also looks at the effects of radiation on French Polynesia as well."
Mr Robie says it was a traumatic experience witnessing the moving of islanders from their homeland to Mejatto and Kwajalein atolls.
