The country's longest-running property dispute heads back to Court - nearly 180 years after the Crown promised Māori landowners in Nelson they'd keep at least one-tenth of their land if they sold to the New Zealand Company.
But that promise was broken; and in 2017, the Supreme Court ruled that the Crown had a legal duty to reserve the customary Tenths.
The parties are now heading back to court to determine the extent of the breaches and the remedies.
University of Auckland constitutional lawyer Claire Charters spoke to Ingrid Hipkiss.
