If it wasn't for controversy caused by the film Argo - a diary outlining New Zealand's involvement in the Iranian Hostage Crisis might never have come to light.
The film depicts the escape of six US diplomats following the 1979 revolution.
It incorrectly claims New Zealand refused to help.
Richard Sewell was second secretary at the New Zealand Embassy in Tehran at the time and his partner Grant Allen says the notes show what really happened.
He says it's real life evidence of what happened, and as it's not an official document it's not covered by confidentiality.
