About This Data
Auditor information is sourced from iwi annual report financial statements. Not all iwi disclose their auditor in publicly available reports. Auditor names have been normalised where variants exist (e.g. "BDO Wellington" and "BDO Rotorua" are grouped under "BDO"). Tenure is calculated from available data years only and may undercount actual engagement length. This page presents data availability only and does not assess audit quality or independence.
Data sourced from Iwi annual reports and financial statements. Our datasets may not be complete. Automated analysis can produce errors. If you believe any data on this page is incorrect, please contact us at hello@nzxplorer.co.nz.
