A member's bill from NZ First MP Jenny Marcroft that would amend the Legislation Act 2019 to add standard definitions used across New Zealand statutes: 'woman' would mean 'an adult human biological female' and 'man' 'an adult human biological male', applying regardless of a person's gender identity.

Supporters — NZ First, National and ACT — say it would give the law clarity and consistency and protect sex-based rights and single-sex spaces in areas such as sport and healthcare. Opponents — Labour, the Greens and Te Pāti Māori — say it would exclude and stigmatise transgender and intersex New Zealanders and cut against existing law that lets people change the sex recorded on their birth certificate. The Attorney-General's report also flagged that, because the definitions cover only 'adults', they could sit awkwardly with the Bill of Rights Act's protection against age discrimination.
