Bay of Plenty Police investigating the death of Eli Johnson in Whakamarama want to speak to the occupants of a vehicle in the area at the time.

Eli, 27, died at a Whakamarama property on Sunday, June 12, and a homicide investigation is ongoing.

Detective Inspector Lew Warner says the investigation team continues to make progress and is working hard to identify all vehicles that were travelling in the Whakamarama and Te Puna areas at the time of Eli's death.

The above photo shows two vehicles of interest, in terms of gathering information about what happened to Eli.

"While we've since identified and spoken with the occupants of the white utility, we'd like the occupants of the silver sedan pictured to come forward and speak with us," Detective Inspector Warner says.
