Methodology
Tenure is calculated from appointment dates recorded in iwi annual reports. Board churn measures the percentage of current officers appointed within the last 2 years. Revenue and asset growth are year-on-year from the two most recent financial years available.
Correlation does not imply causation. Many factors beyond board tenure affect iwi financial performance, including settlement timing, investment markets, and operational scale. Sample sizes are small and results should be interpreted with caution.
Financial data from iwi annual reports. Officer appointments from governance disclosures. Only iwi with 3+ current officers and recorded appointment dates are included.
Data sourced from Iwi annual reports and governance disclosures. 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@iwidata.co.nz.
