Alo Ngata, 29, died in Auckland Hospital three days after a fracas with police as they tried to arrest him following an incident on Sunday afternoon in Freemans Bay.
Police allege Ngata violently attacked a 76-year-old, kicking him five or six times in the head and rendering him unconscious.
He then blocked police from getting to the injured pensioner and advanced on officers in a threatening manner.
Police Tasered Ngata several times but he continued to resist them.
It took four officers to restrain him.
