Wellington City Council's confirmation vote on its long term plan to be put out to consultation, has been delayed until next week, as the auditor has not yet finished their audit.
The plan, which acts as a 10-year budget for the council, has gone through numerous meetings since, mid-February.
A final version was agreed upon in early March, with today's meeting just a formality to approve the consultation document, and sign off on the audit.
But that has now been postponed to next Tuesday, with the auditor requesting more information from the council, so they can ensure the opinion they do issue is a correct one.
In their audits, other councils across the Wellington region have been warned about the risk of spending big on water infrastructure.
In the opinion given to Hutt City Council, the auditor said there was "an inherent level of uncertainty and risk that the council may not be able to deliver on the programme, especially when it has increased substantially."
Meanwhile, auditors have also expressed concern over the reporting put in place by Wellington Water - the authority which oversees the region's water network.
In their opinion to Upper Hutt City Council, the auditor wrote: "Council's forecasting for three waters assets is based on age.
"Using only aged based information means there is a higher degree of uncertainty on how the council has prioritised its investment needs.
"Wellington Water Limited will work on better understanding asset condition, which will improve the reliability of future investment needs."
