Which Act regulates abortion in New Zealand?

The Contraception, Sterilisation, and Abortion Act 1977 is the correct answer because it is the specific piece of legislation that governs the provision of abortion services in New Zealand. This Act outlines the legal framework for accessing abortion, including the criteria that must be met and the processes involved in obtaining an abortion. The Act was designed to ensure that women have the right to access abortion services while regulating the conditions under which these services can be provided.

The other options do not directly pertain to the regulation of abortion. The Care of Children Act 2004 focuses on the welfare and guardianship of children, addressing matters related to their care but not directly influencing abortion laws. The Health and Disability Commissioner Act 1994 establishes the framework for protecting the rights of health and disability services consumers, which encompasses various health rights but does not specifically regulate abortion practices. The Human Rights Act 1993 provides a broad spectrum of rights protection but does not specifically address abortion or the processes surrounding it. Therefore, the Contraception, Sterilisation, and Abortion Act 1977 is the most relevant and specific legislation regarding abortion in New Zealand.
