Section 133A allows a council to issue an amended consent that corrects minor mistakes or defects in the consent (including the conditions) within 20 working days of the date that consent is granted. In addition, s13 of the Interpretation Act 1999 provides the power to correct errors outside the 15 working day time frame afforded by the RMA. Specifically “The power to make an appointment or do any other act or thing may be exercised to correct an error or omission in a previous exercise of the power even though the power is not generally capable of being exercised more than once”.
