What this bill does
The bill passed its first reading 67–55; the vote was not unanimous. According to the bill’s explanatory material, the legal meaning of “woman” and “man” may be unclear or inconsistently interpreted, affecting sex-based rights. The bill aims to give those terms a consistent biological meaning across New Zealand legislation. The bill would amend the Legislation Act 2019 so that, in any legislation regardless of gender identity, “woman” means an adult human biological female, “man” means an adult human biological male, and “female” and “male” mean human biological female and male.

Arguments raised in Parliament
AI-assisted summary of the linked Hansard debates. Each point is grounded in the cited transcript.
Arguments for
The bill would give biological women and men legal certainty by setting default definitions across the statute book, preventing conflicting or ideologically driven interpretations.
Defining sex in law would protect women’s and girls’ safety, privacy, and fairness, including by preserving female-only spaces and preventing male physical advantages from compromising female sport.
Clear biological definitions would enable healthcare, safeguarding, and discrimination measurement to account for sex-specific differences and protections.
Arguments against
Because most legislation is gender-neutral and targeted laws already use precise sex-specific language where needed, imposing sweeping definitions may create complexity without a tangible legal benefit.
The bill’s adult-only definitions could unlawfully discriminate by age and exclude under-20s from statutory provisions using “woman” or “man”, jeopardising protections and services.
By excluding trans people from self-chosen definitions, the bill would marginalise trans, intersex, and gender-diverse communities and cause social harm.
The bill could conflict with existing human-rights protections for gender identity and fail to reflect intersex people with variations in sex characteristics.
Nuance and qualifications
National supported referral rather than endorsing the bill’s outcome, arguing that select committee scrutiny should test its assumptions, evidence, unintended consequences, and the identified age-discrimination defect.
Supporters argued that recognising biological sex should coexist with dignity and protection from harassment for trans people, rather than removing others’ rights.
