The findings were initially expected to be presented to council at its meeting on Tuesday.
However, those findings will now be made available to the audit and risk committee and full council in August to consider.
Along with Thomson's review Impact Consulting is carrying out an online survey.
In a report prepared by Governance Group project director Pete Thompson, it says “due to the timing of the survey results the subsequent report” has been delayed until August.
The report for Tuesday’s meeting also provides a budget update for the “working on working together” project.
The council had budgeted $310,000 for the financial year ending June 2021.
