"Research evidence shows that early intervention and identification of high social risk mothers is best practice and will lead to better outcomes for the babies," she said.
"Any concerns with regard to the unborn baby, the capability, capacity of the mother or parents, the wellbeing of siblings and the history of the family will be discussed with NDHB and CYF as soon as the pregnancy has been confirmed. The database will help build a bigger picture of a child's welfare."

New Zealand Medical Association chairman Paul Ockelford said the information-sharing system was a step in the right direction.
"One of the things we submitted was to have a much closer involvement of the at-risk child with what we call the medical home - multi-disciplinary general practice. I think we see the focus on better information sharing ... to capture information on neglected, abused, at-risk children as a real positive," Dr Ockelford said.
Plans to red-flag abusers were included in the paper.
