Police and Navy divers are continuing searching into the evening for the body of a teenage boy presumed dead after a jetski accident on a lake near Rotorua, while family and friends continue to hold vigil on the shoreline.
The divers have been searching a 400 metre by 500 metre stretch of Lake Okareka for 17-year-old Rotorua High School pupil Bishop Thompson, who has not been seen since Saturday.
Acting area commander Senior Sergeant Ed van den Broek said visibility was just over one and a half metres in the lake, and the 30 to 33 metre-deep water meant using sonar equipment was the best option available to searchers.
"The bottom is a combination of mud and silt and any movement in the area stirs up the bottom, limiting visibility even further," he said.
Police were also re-interviewing witnesses and reconstructing events to try and establish which areas should be double checked.
