Kaipara District Council will seek a parliamentary solution to resolve the district's historical rating errors.
At a recent meeting, commissioners agreed a local bill was the best option in dealing with all the irregularities "once and for all".
They were clear, however, that a local bill would not hinder possible
legal action by the council over matters around the 2006 extension of the Mangawhai Community Wastewater Scheme.
The auditor-general's office is investigating the scheme with a report due next year. Commissioners will consider the report with urgency and have not yet discounted legal action against those involved.
Commissioner Peter Winder said the community had understandable concerns over the the scheme's extension. "The bill is not validating this ... opportunities for redress are important."
