Users will be able to view a child's case and compare their own notes with those of other professionals working with that child.
Mrs Griggs said teachers would definitely find the database useful.
"It is essential that we have open lines of communication. And if schools are aware of children's emotional needs, then they'll be able to cater for them," she said.
The database is part of a raft of legal reforms planned to tackle child cruelty in New Zealand over the next five years.
It was developed by the University of Auckland, which assessed 52,000 children over a five-year period whose parent or parents were on a benefit.
New Zealand Medical Association chairman Paul Ockelford said the information-sharing system was a step in the right direction.
"I think we see the focus on better information sharing ... to capture information on neglected, abused, at-risk children as a real positive. It should provide an early alert system to be able to detect those who are most at risk."
Plans to red-flag child abusers were included in the paper. Measures such as protection orders for potential abusers and alerts for high-risk adults who move into homes with children were outlined.
However, the initiatives stopped short of mandatory reporting of suspected child abuse cases.
"[Social Development Minister Paula Bennett] obviously shied away from mandatory reporting because of some potential concerns in some countries of what that has been, both from the point of view of under-reporting and possibly over-reporting the ... false-positives," Dr Ockelford said.
Progress checks on the new database and information sharing system would be crucial to measuring its success, he said.
Use of the database will be strictly monitored, with penalties for any inappropriate use.
