New Zealand is very similar to Australia.
There are very, very, few children available for adoption. In very rare instances when women decide they wish to adopt a child out, there is a lot of effort put into helping them explore whether they really wish to do so, or whether they could with support, retain the child. Open adoptions are encouraged, if the decision to adopt is made, with the child being aware they are adopted, and communication and contact between the adoptive parents, child, and the birth parent. A further complication is the Maori practice of whangai, which is an informal adoption within the extended family of a child.
There is a lot of emphasis on working with the families to enable them to become safe and effective parents. There is also a focus if a child needs to be removed, on trying first to find a placement within the extended family, and within the child's race and culture, particularly if the child is Maori.
A good part of this is a belief that this is fulfilling our obligations under UNCOROC - maintaining a child's rights to maintain links with their biological family wherever possible, and links with their cultural heritage.
There is also long term foster care, and 'Home for Life' - where it seems you get all the disadvantages, both as foster parent and of foster child of fostering, but none of the benefits in terms of state support and (inadequate) funding.
Is there a national children's welfare department within the world that is adequately funded, resourced, and staffed, I wonder?
I honestly didn't realise that the state could unilaterally terminate parental guardianship rights and responsibilities over here. I'm still wrapping my head around it.
My mother was in foster care as a child, because of a terrible accident to her mother that meant the family unit couldn't stay together. She went to a lovely couple, who wanted to adopt her. To this day, she recalls the terror that they would, and she would be permanently bereft of her family.
