Rotorua police have enlisted the help of Police Ten 7 to help solve the death of Israel Jack, who was killed on Te Ngae Rd a month ago.
The TV2 programme will feature the investigation on this Thursday's show, which screens at 7.30pm, and yesterday filmed segments at key locations on Te Ngae Rd.
Mr Jack, known to family and friends as Issy, was 20 years old and lived in Edgecumbe.
The former Rotorua Boys' High School student had been out with friends in the CBD, but had separated and started walking back to where he was staying.
"While this programme goes out nationally, the answer to this will lie in Rotorua," said Police Ten 7 presenter, retired Detective Inspector Graham Bell.
