civil union can jointly adopt children following a New Zealand High Court ruling in December 2015. The court ruled that the ban breached the New Zealand Bill of Rights Act 1990. The minimum age to adopt in New Zealand is 20 years for a related child and 25 years or the child's age plus 20 years (whichever is greater) for an unrelated child. On 21 May 2006, Green List MP Metiria Turei raised the issue of LGBT adoption, arguing that New Zealand's Adoption Act 1955 did not meet the complexities of contemporary New Zealand society. She argued following the enactment of civil unions in particular that eligible lesbian and gay prospective parents should be enabled to legally adopt. Many lesbian couples are now raising children in New Zealand. Where these children are conceived through donor (sperm) insemination, both partners are recognised on the children's birth certificates (the birth mother as "mother", the other mother as "other parent"). This is following the Care of Children Act 2004, which repealed and replaced the Status of Children Act 1969. Fostering and guardianship are also recognised under New Zealand law and regulation, and reproductive technology has been accessible since 1994. The donor is not recognised as a legal parent in New Zealand law. However, parents and donors can make formal agreements as to how things will work but the courts do have flexibility as to whether they recognise these agreements or not, under section 41 of the Care of Children Act 2004. Lesbian women who have trouble conceiving using private donor insemination may be eligible, as other New Zealand women are, to help through publicly funded fertility treatment. However, there are conditions on this and every woman needing fertility treatment is scored as to her eligibility. Now passed, the current Marriage (Definition of Marriage) Amendment Act 2013 enables eligible married same-sex parents to adopt children as there is a clause to that effect contained therein. However, known-relative adoptions in New Zealand have outnumbered stranger adoptions since the mid-1970s; between 2007 and 2013, there were 18 known-relative and stepchild adoptions for every 10 stranger adoptions. Discrimination protections The Human Rights Act 1993 () outlaws discrimination on the grounds of sexual orientation and, implicitly, gender identity/expression. Initially, this law temporarily exempted government activities until 1999. In 1998, an amendment bill was introduced making this exemption permanent; this was abandoned following a change of government in 1999.
