Hamilton city councillors are at odds with some senior council managers, who they say are "vetting" information given to the council.
The Herald has seen emails between senior managers co-ordinating how and when information is presented to councillors.
But the authors of the emails, Hamilton City Council deputy chief executive Blair Bowcott and general manager of infrastructure Chris Allen - say there was no intention to mislead or hide information.
The council's finance and monitoring committee chairman, Dave Macpherson, and councillor Ewan Wilson say the emails imply staff are vetting information councillors get.
Mr Macpherson said councillors should be given information "warts and all".
