What changed

The High Court of New Zealand has ruled in Kapa-Kingi v Tamihere ([2026] NZHC 517) that resolutions by Te Pāti Maori leadership to suspend and subsequently expel the first applicant from party membership were unlawful under the party's constitution. The court ordered the setting aside of these decisions and reinstated the applicant as a party member. However, the court found no invalidity in the re-election process of the party president, thus dismissing that aspect of the claim.

This decision has immediate implications for the internal governance and disciplinary procedures of Te Pāti Maori, requiring adherence to its own constitution. For compliance officers involved with political organizations, this case underscores the importance of ensuring that internal party rules and procedures are followed to avoid legal challenges and potential reinstatement orders. While no specific compliance deadline is mentioned, the ruling implies that any ongoing or future disciplinary actions must strictly align with the party's constitutional framework to be considered valid.

What to do next

Review internal party constitutions and bylaws for compliance with stated procedures.
Ensure all disciplinary actions against members strictly follow established constitutional guidelines.
Document all steps taken in membership suspension or expulsion processes.

Summary

Application for judicial review of a political party leadership's conduct on the basis it was unlawful under the party's constitution. The first applicant, a Te Pāti Maori electorate MP, claimed that members of her party's leadership had unlawfully suspended and then expelled her from Pāti membership. The applicants also claimed that the Pāti president had not been validly re-elected, making his presidential actions since the expiry of his first term invalid. The applicants sought relief including the reinstatement of the first applicant as a member of the Pāti.

Held: Application granted in part. Declarations made that the first and/or second respondents' resolutions to suspend and then expel the first applicant from Pāti membership were unlawful under the party’s constitution. Order made setting aside those decisions, reinstating the first applicant as a Pāti member. Court found no invalidity in the process leading to third respondent’s re-election as Pāti president, so the cause of action failed.
