Billy Dawson was punched in the face shortly before he fell over and sustained a fatal head injury, a court has heard.
The 34-year-old Sky Television employee had been at Spy Bar in the Viaduct when he got into an "altercation".
He was rushed to Auckland Hospital but died only hours after the attack.
Details of the alleged assault were revealed at the Auckland District Court today.
Kit John Murray has been charged with assault and police have indicated more serious charges could be laid.
