Concern is being raised that child abuse doesn't get enough coverage in the media.

A four-month-old girl was admitted to Auckland's Middlemore Hospital four weeks ago after receiving 16 fractures to her skull, ribs, arms and legs.

Her family is refusing to tell police what happened.

"The fractures have been described by medical experts as being of varying ages and classically associated with non-accidental injury," Detective Senior Sergeant Eddie Sutherland told the Herald.

"Thankfully, the child is going to make a full recovery, however police are extremely concerned by these injuries."

Great Potentials Foundation co-founder Dame Lesley Max told Mike Hosking a quarter of Kiwi children under 17 are the subject of notification to child protection.

"That is a massive shame but it was the news of the day and [now] it's gone."

Dame Lesley says child abuse is our most predominant concern as a country and it can't all be ascribed to poverty.

She says it is very sad that the family has closed ranks. She says someone will know what happened to the baby; there'll be someone who's seen bruises, or have heard crying.

"There is a 0800 number, where people who don't want to leave their names can leave information."
