Police investigating the murder of security guard Charanpreet Singh Dhaliwal last year are appealing to the Polynesian community to identify four young men seen near a west Auckland construction site where his body was discovered.
Mr Dhaliwal, 22, died of head injuries after being assaulted.
His body was found slumped over a slab of concrete at a Fulton Hogan construction site in Henderson near the northwestern motorway about 3am on November 18.
As part of the police investigation, the Police 10-7 television series will screen details about the homicide on Thursday evening.
Detective Sergeant Murray Free of Waitakere CIB said he hoped this would identify a group of four Polynesian men aged 17-20 who were in the area around the time Mr Dhaliwal's body was found.
