Investigators looking into an allegedly forged document sent from Energy Minister Angus Taylor's office found no evidence the original document was downloaded to his office, despite his claims to Parliament.

NSW Police could not find any metadata to prove a device in Mr Taylor's office downloaded the City of Sydney's annual report from its website. A fake version of the report was sent from his office to a newspaper to attack Sydney lord mayor Clover Moore over the City of Sydney's travel expenses.

Mr Taylor used the faked version to claim the council spent $15.9 million on travel when the real costs were less than $6000. He later apologised to Cr Moore.

In answers to questions on notice to a NSW parliamentary committee, NSW Police Commissioner Mick Fuller said police could not confirm when Mr Taylor or his office downloaded the documents from the City of Sydney website.
