Crime show Police Ten-7 has yielded "invaluable" information for police investigating an Otaki homicide, however they are pleading for more witnesses to come forward.
A 24-year-old Hamilton man was charged with murder last month after the body of 30-year-old Huntly man Edward Tahakura was found on Otaki Beach on September 12.
Last week's Police Ten-7 show featured the case and an appeal for three people who gave a hitchhiker a ride.
Detective Sergeant Gary Milligan, who is leading the homicide investigation, said police received four calls, which while small in number, yielded "invaluable" information.
"The investigation team are grateful for the information provided from the public and we are still receiving a few calls. This shows that the public are keen to help us with our inquiries."
Officers have located and spoken to a truck driver who gave the man a ride and are looking to speak to two more drivers, Mr Milligan said.
"These drivers are not in any trouble - we need to speak to them to piece together [his] movements."
The 24-year-old hitchhiker is described as being of Maori descent, with a medium build, approximately 1.8 metres tall and with closely shaven black hair.
Anyone with information is asked to contact Detective Sergeant Milligan on (06) 351 3781 can provide information anonymously through Crimestoppers on 0800 555 111.
