Council group chief financial officer Grant McKenzie said 257 staff had received training during four sessions held in recent weeks.
Four more sessions were planned, but more could be held later, as the council sought to ensure all staff received the training, he said.
The council's senior staff were receiving more ''in depth'' training, and would also be expected to provide training to any new staff recruited in future, as part of their induction, he said.
The training would also be repeated every six months to a year, at least at a managerial level, he said.
''We are trying to get as many people in the organisation covered as we can,'' he said.
Mr McKenzie was speaking at yesterday's council audit and risk subcommittee meeting.
His comments came in the wake of the discovery of the council's Citifleet fraud, involving the sale of 152 council cars and the pocketing of proceeds, which cost the council $1.5 million.
The fraud training was part of sweeping changes designed to improve the council's fraud protection and ensure there was no repeat.
The council had commissioned Deloitte - the same firm that investigated the Citifleet fraud - to provide training for the council's 750 full and part-time staff, at a total cost of about $14,000.
The training sought to help staff understand how corruption and fraud could materialise, as well as red flags to look for and what to do if fraud was suspected.
Mr McKenzie told yesterday's meeting the training was ''positively received'' by council staff, and had prompted ''interesting'' questions at the end of each session.
One staff member had raised concerns about a particular gap in council systems, only to be reassured it had since been closed, Mr McKenzie said.
He approached the person afterwards to question why they had not raised concerns earlier, and was told by the staff member they had never thought to do so before.
That showed the training was having the desired effect, he said.
