A man has been charged with murder after his alleged assault victim died in Auckland's Middlemore Hospital last night.

Sanele Sanato, 36, died as a result of injuries received in a Wednesday night assault, Detective Senior Sergeant Gary Lendrum, of Counties Manukau CIB, said today.

He said an investigation had resulted in the arrest of a 34-year-old Manurewa man, who would appear in Manukau District Court today charged with murder.

"The investigation is continuing with a team of 20 investigators," Mr Lendrum said.

"No one else is being sought in relation to the assault. The two men were known to each other."

The dead man, who was unemployed, lived in Glen Innes, in the eastern suburbs of Auckland.
