The internal report is referred to in documents from the inquest into the death of Rodney David Marks, 32, an Australian astrophysicist, who died in Antarctica under mysterious circumstances.
The Herald on Sunday was last week granted access to the documents, which reveal heavy drinking and drug use at the American-run Amundsen-Scott South Pole Station.
The documents come from the New Zealand inquiry into Marks' death in 2000, which began after an autopsy in Christchurch discovered he had been poisoned by a fatal quantity of methanol.
They detail eight years of "legal, diplomatic and jurisdictional hurdles" faced by police - and have led to new rules being developed to deal with sudden deaths in Antarctica.
Wormald was trying to get copies of the foundation's inquiries into Marks' death, and contact details for the 49 other people who spent winter at the South Pole that year.
Letters reveal no foundation inquiries were provided to Wormald and the agency would not provide contact details for witnesses - only forwarding a questionnaire after approving the questions.
Wormald managed to get hold of one inquiry from a former employee. The report, by a foundation doctor, stated "when an individual aged 32 years dies unexpectedly, the matter warrants a homicide investigation".
The doctor said the inquiry should be carried out even though there was no evidence to suggest murder - or that the death was an accident.
Despite the advice, South Pole station staff were left free to clean Marks' room, disposing of potential evidence as rubbish.
The foundation also did nothing to halt the 49 people leaving Antarctica from disappearing across the world without being interviewed after landing in New Zealand. READ MORE
