Is Dating Siblings Legal in New Zealand After the 2026 Law Changes?

No, dating between siblings is illegal in New Zealand under the Crimes Act 1961, which criminalizes incest. Consent does not negate the prohibition, and penalties include imprisonment. The law reflects cultural and genetic concerns, enforced by New Zealand Police.
