French secret service agent Christine Cabon has been found but refuses to apologise for her part in the bombing of the Greenpeace ship, the Rainbow Warrior, in Auckland Harbour.
Monday marks 32 years since the bombing that killed photographer Fernando Pereira.
Fairfax has tracked Ms Cabon, who infiltrated Greenpeace to help plan the Rainbow Warrior bombing before disappearing, to a small village in France.
She says she regrets the death of Mr Pereira, but won't be apologising and will respect her contractual obligation to the army which forbids her speaking for 50 years after seeing active service.
"My job was what it was. I entered the army to prevent international and national conflict because my family, originally from Alsace, suffered from the war," she tells Fairfax.
"I think all military people who serve their countries can find themselves in situations they hadn't wished for."
In April 1985, Christine Cabon introduced herself to staff at Greenpeace's Auckland offices as aristocrat and activist 'Frederique Bonlieu' with a letter from Greenpeace in Paris.
She made friends with Greenpeace directors and volunteers, while acquiring details of its workings.
"In Auckland, they were happy to get a Frenchie to help in an anti-French nuclear testing operation," French historian Gerald Arboit says.
She flew to Israel just before the bombing and then two weeks later as police were about to arrest her, she fled to France.
Retired Detective Superintendent Allan Galbraith tells Fairfax he's not surprised at her reluctance to apologise.
