A homicide investigation is underway after the death of a 61-year-old man at Auckland Hospital overnight.
Christopher Edwards was found unconscious with an "unexplained life-threatening head injury" at his Northland home on Tuesday night and taken to hospital where he had surgery to relieve pressure on his brain.
His life support machine was switched off yesterday afternoon after doctors decided there was nothing more they could do. He died at 4am today.
A 42-year-old man appeared before Dargaville District Court today charged with assault. He was remanded in custody and will reappear on Tuesday.
An ambulance was called to Mr Edward's home, about 13km southeast of Dargaville after he could not be woken.
