A relative of the 4-week-old baby who died in Kaitaia on February 19, as the result of non-accidental injuries, has appealed for the public's help with the police investigation.
"We want to know what happened to our mokopuna," family spokesman Bardia Matiu said yesterday.
"Our whānau are united in our support of the police in their search for the truth."
Acting Detective Inspector Lloyd Schmid, who is leading the investigation, said a post mortem examination and other information police had gathered indicated Maree had died of a non-accidental brain injury and bleeding to her brain. Severe bruising was also found on one arm and thigh.
A team of investigators were currently speaking to a large number of people, in Northland and further afield.
