The company assessed the council as between "Foundation" and "Established" levels on a procurement maturity curve, suggesting that it should aim for at least "Established" level.
"While this review has identified a number of areas for further improvement, we note that these findings are relatively consistent with a number of other district councils," the report said.
The council had introduced several initiatives over the past year to improve its procurement function, including setting up a procurement board and centre of excellence within the organisation, revising a procurement policy, and developing tools, guidelines and training for staff.
"We identified a number of key strengths that management should continue to build upon to develop a robust control environment over FNDC's procurement function. These will need time to be embedded across the organisation to produce consistent results," it added.
The council's previous procurement policy had not been well embedded across the organisation, or tailored to suit the council's needs, resulting in inconsistent procurement practices, non-compliance with policies and procedures, and a largely decentralised procurement model.
Mayor John Carter said the council commissioned the fully independent review because it wanted residents and ratepayers to be confident that its procurement procedures were fair, robust and transparent.
"While the audit did not constitute a deep-dive forensic investigation into the procurements, KPMG did not find any indication of fraudulent activity by council staff," he said.
