The police national dive squad is focusing its search for a man believed murdered on a South Canterbury river and nearby waterways.
The squad was called in to help with the investigation into the disappearance of Anaru Moana, 37.
The search area, known as the Waihao Box, was close to where a silver Subaru was found burned out two days after Anaru’s disappearance in December last year.
Police earlier said the movements of those linked to the vehicle between the time the father-of-two went missing and when the vehicle was disposed of were being traced.
