Police are combing the large property where a Helensville man was found dead for clues that could lead to his killer.
The body of 32-year-old Lee McMurdo was found late on Friday afternoon, and police believe someone else was involved in his death.
Investigators were still at his home on SH16 yesterday and police say they will be there for several days.
Since detectives made a public appeal for information about the death - and for sightings of Mr McMurdo - they have received calls from members of the public.
They would not reveal the nature of the calls they have received, or the cause of Mr McMurdo's death.
