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 slumpedover 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.
"Police want the wide Polynesian community to be aware of this screening. Someone in this community may have vital information that could help Police solve this homicide,'' he said.
Mr Dhaliwal was born in India but came to New Zealand to study about two years before his death.
His friends and family described him as a "kind soul'' who came here for a better future and education.
Anyone with information was urged to call 0800 OP HOPE - 0800 674 673 - or Crimestoppers anonymously on 0800 555 111.
