A Whangārei man is now facing a charge of murder in relation to the death of a 5-month-old boy.
The 28-year-old, from Raumanga, reappeared in the Whangarei District Court today and the interim name suppression put in place during his first appearance last week will continue.
The man's initial charge of assault on a child was withdrawn during today's appearance before Judge David Sharp and a new charge of murder was filed.
The new charge carries a maximum penalty of life imprisonment.
Police launched a homicide investigation after they were called to a Raumanga house by ambulance staff two weeks ago.
