Kaipara District Council’s wastewater project - an expensive audit failure?

The report of the Auditor-General’s inquiry into the EcoCare wastewater project was released on Tuesday. It revealed serious failures in the management of the project, and strongly criticises Audit NZ. Inaccurate record keeping, mismanagement of the project, lack of financial advice and expertise, and reliance on private partnerships saw a huge budget blowout, with costs exceeding over $63m. For example, the effluent disposal bill alone increased from $361,000 to $14m.

How did the Council pay for this budget blowout? By raising rates for Mangawhai residents. The annual cost to ratepayers was a consideration in assessing the affordability of the project. However, the summary of the report reveals that the Council in fact decided to “increase the number of estimated ratepayers that would be covered by the scheme and contribute to funding it”. This is a fundamental flaw, and the Auditor-General concluded that this decision was not based on an adequate account of predicted growth in the area. This, as well as the undisclosed liabilities are precisely the things Audit NZ should have picked up on.

Overall the report suggests Audit NZ was failing audit 101

The Auditor-General's office (which includes Audit NZ) is supposed to provide assurance that government departments are performing as they should. The report details that:

• audit quality of the project was varied;
• the quality of documentation for some audit files were inadequate, especially those explaining why judgments were reached;
• there was a failure to reassess the project between 2006-2009 despite significant changes that could have been an audit risk; and
• the auditor’s reliance on information from Kaipara District Council’s management (which, from our examples above, were also clearly inadequate).

Joel Cayford has written a blog post evaluating the report. He’s gone a step further than the Taxpayers’ Union, and believes that an unreserved apology does not cut it, concluding that the Auditor-General's 'head is on the block'. 

Many audit failures internationally have led to large payouts by audit companies and their insurers to shareholders. Here, the tab was left with Kaipara ratepayers. The report does not address what we think the issue is: redress for the Kaipara ratepayers who paid the bill.
