Mr Taylor used an allegedly falsified document which he claimed had been "drawn directly from the City of Sydney's website" in September last year to attack Lord Mayor Clover Moore over climate change policies.

In a letter to Ms Moore, Mr Taylor attacked the council over the document which he claimed outlined $15.9 million in domestic and international travel expenses in a single year.

The letter was leaked to The Daily Telegraph newspaper.

However, the figures Mr Taylor relied on from the council's annual report were wrong and were actually closer to $6,000.

The Energy Minister told Parliament in October the document had not been forged by himself or a member of his staff and "was drawn directly from the City of Sydney's website. It was publicly available".

But NSW police have confirmed metadata did not "provide any evidence of the document being downloaded by Mr Taylor's office".

In NSW Budget Estimates, NSW Police Commissioner Mick Fuller was asked whether police had established when the Minister or his office downloaded the documents from the City of Sydney website.

In a recently published response, Commissioner Fuller said investigators could not confirm when or if Mr Taylor or his office downloaded the document.

"The metadata did not provide any evidence of the document being downloaded to Minister Taylor's office," Commissioner Fuller said.

NSW Labor MP Rose Jackson also asked whether NSW police had found "any evidence that the document Mr Taylor or his office provided to journalists at The Daily Telegraph … had ever existed on the City of Sydney's website".

Mr Fuller, who also took this question on notice, responded that "no" evidence of this was found.

A spokesman for Mr Taylor said the document was accessed on the council website and printed to a hard copy directly from there, rather than being "downloaded".

"The NSW police are only confirming what we have said all along," the spokesman said.

"We have always maintained that the report wasn't downloaded."

Mr Taylor has previously claimed that neither he nor his staff altered the document, and said there was evidence that multiple versions of the document existed on the City of Sydney's website.

Shadow Federal Attorney-General Mark Dreyfus asked New South Wales Police to investigate the matter in October.

It was then referred to the Australian Federal Police for consideration but later dropped, with Commissioner Reece Kershaw telling Senate Estimates in March that the "matter was finalised".

A spokesman for Mr Taylor said the Minister provided a statement to NSW Police and also responded to written questions.

"Minister Taylor did not refuse to be interviewed by the NSW Police as media reports suggest," the spokesman said in a statement.

"The NSW Police have stated in their response to questions on notice that cooperation was provided throughout their enquiry."
