The issue of gay adoption is set to make its way on to the parliamentary agenda in a private member's bill sponsored by Labour list MP Jacinda Ardern.
But it is not likely to be as polarising as Louisa Wall's gay marriage bill that passed its first hurdle in Parliament on Wednesday.
Ms Ardern's private member's bill would require the Law Commission to update a report it wrote around adoption and its alternatives.
The bill intends that the report include issues such as adoption by gay couples. It does not directly legalise adoption by gay couples.
Ironically, the Louisa Wall bill legalising gay marriage would also legalise gay adoption because it would bring same-sex couples into definition of a spouse (or marital partner) - who is legally entitled to apply for adoption under the current Adoption Act.
