Police want the public's help finding out who had a firearm before a fatal shooting in the Wellington suburb of Karori last year.
Rau Tongia was shot and killed on 20 December.
Six people have since been charged in relation to his death, and police are not ruling out further arrests.
They say they want to know who had the firearm in the days and weeks leading up to the shooting, and whether anyone else helped the primary offender on the night.
Anyone with information is asked to contact Police on 105 and quote file number 201220/8063, or provide information to Crimestoppers anonymously on 0800 555 111.
