Transpower responded and provided a director's compliance statement and audit report.

The compliance statement did not in all respects comply with the Electricity Commission's request, as it did not state that Transpower's directors were satisfied:

that the revenue requirement has been calculated correctly, and specifically, that the Commission-approved amounts have been correctly assigned to the appropriate fixed assets included in the regulatory asset base.

In response to the Commission's request to include the above in the directors' statement, Transpower provided an independent assurance report.

The Electricity Commission was satisfied that the information provided by Transpower in the independent assurance report covered the outstanding request.
