Jones' latest outburst comes following the recent signoff of almost $5m to Manea Footprints of Kupe, a culture, heritage and education centre in Northland. Jones declared a conflict of interest in the project when he became the fund's benefactor as it was set up as part of the coalition deal with New Zealand First.
He had a conflict because he'd advocated for the cultural centre before becoming a minister and had attended a meeting of ministers last year when the money for the project was being signed off.
The minister's bible, the Cabinet Manual, gives them guidance on how to manage conflicts of interest which obviously precludes them from approving or signing off projects requiring taxpayers' funds. This one had actually been opposed by Treasury, although it would seem the Government's advisers are being taken less notice of these days.
So why did the conflicted minister sit in on the meeting with his colleagues on this project? Jones says to provide the facts and 'the bible' doesn't require them to absent themselves.
But surely the ministers would have had all the facts they needed, considering they had already been briefed and were deciding to hand over so much money. Minutes from the meeting show reassurances from Jones about the project were good enough for Finance Minister Grant Robertson, and ministers Kelvin Davis, David Parker and Phil Twyford to approve it.
So much for his non-involvement.
Given Jones was the only minister from the all-powerful Peters Party he should have - at the very least - left the room and let the others to make up their minds without his influence.
Jones says his declaration of a conflict of interest was more about perception than reality.
Well politics is about perception - and Jones would do well to bear in mind it's the very thing that gets people elected and Governments defeated.
