Police have charged two people after a 4-month-old Howick baby was admitted to Middlemore Hospital with 16 fractures to her body.

The Herald can reveal that a 28-year-old man from Howick has been charged with wounding with intent to cause grievous bodily harm.

A 30-year-old woman has been charged with attempting to pervert the course of justice.

Both are set to appear in the Manukau District Court tomorrow.

Earlier this month it was revealed the baby girl was injured over a period of time and when she was finally admitted to hospital she had fractures to her skull, arms, legs and ribs.

Police described the injuries as "significant" and along with medical experts, believe they were not accidental and someone deliberately harmed her.

The baby's parents took her to their doctor on February 18.

The doctor, concerned at the state of the child, referred her to Middlemore Hospital where she was admitted.

There, medical staff established that she had 16 fractures of various ages - meaning the injuries were not inflicted during one incident.

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

Last week the Herald visited the house where the baby lived with her parents.

Family members of the baby refused to comment.
