Hamilton foster parents have called for an overhaul of adoption laws, saying birth parents who repeatedly abuse their children should lose their rights, in the way that boy racers lose their cars.
Wiremu and Sunny Bayliss have given a young girl a safe "home for life", but are frustrated they can't make many decisions without consulting her birth mother, who is transient and only sees her daughter twice a year.
They need the mother's permission each time the girl needs major medical treatment, changes schools or the family move. Even minor events like a haircut can be challenged in court, they say.
They have been told adoption would be almost impossible under the current law because the birth mother has refused consent, so they have gathered more than 1000 signatures on a petition to change the law.
The couple, both teachers, want the courts to grant full parental rights to those who provide long-term, non-family, day-to-day care for children who have been previously subjected to repeated abuse and neglect, including the power to award such caregivers the ability to adopt those children in extreme circumstances.
