"Laws that are no longer valid because of the Adoption Act 1955"
The Adoption Act 1955 has a list of laws that are no longer valid. You can find this list in the part of the act called Enactments repealed. This list was created because of a rule in section 30(1) of the act.
Some of the laws that are no longer valid include the Child Welfare Act 1925, the Infants Act 1908, and the Maori Affairs Act 1953. There are also several Statutes Amendment Acts from different years that are no longer valid.
These laws are listed in the Enactments repealed part of the Adoption Act 1955, which is a separate section that provides more information about the act.
