Police are looking through footage filmed at a 21st birthday party in Gisborne that left two dead and three injured.
Chrysler Stevens-Mark and Kane Taare-Gray were killed during a 100 person brawl at the party on Lytton Road on 23 March.
Investigators were making steady progress and have now spoken to most of those who were at the party, police said.
They would continue to have officers in the area.
They said police still wanted to hear from anyone who was at the party or anyone who had photos or videos.
The police have laid serious assault charges against two men - a 25-year-old and a 29-year-old. No one has been charged yet for the deaths.
