Mr Taylor has previously rejected the suggestion that he or any of his staff changed the document.
He insisted in Parliament that he relied on a document downloaded from the City of Sydney website when he claimed the council spent $15.9 million on travel for its councillors when the real costs were less than $6000.
The City of Sydney cited its own computer metadata to insist the document used by Mr Taylor could not have been downloaded from its site, raising questions about who authored the false information and how it came to be in Mr Taylor’s office.
NSW Police launched Strike Force Garrad to investigate Mr Taylor’s role into the scandal after Labor referred the matter to police.
But now any future investigation will be done by the AFP, which has responsibility for crimes committed in the ACT.
Mr Taylor later apologised to Ms Moore and has conceded he used incorrect numbers over her travel expenses and carbon emissions, but had continued to deny his office forged a false document.
Mr Manuatu, a former president of the Young Liberals, joined Mr Taylor’s office after the May election and was formerly a senior aide to Eric Abetz and adviser for Mr Taylor’s predecessor in the seat of Hume, Alby Schultz.
He was linked to a controversy in 2014 where advisers encouraged federal officials to “massage” their economic forecasts to match the Coalition’s vow to create one million jobs over five years. Amid concern the original estimates would fall short of the target, staffers for Senator Abetz – then the employment minister – asked department experts to adjust their figures to add 160,000 jobs to the projections. Senator Abetz at the time rejected claims his office had interfered in the department’s analysis.
