Police hunting the killer of road worker George Taiaroa have focused their attention on a tiny Taranaki settlement.
The inquiry head, Detective Inspector Tim Anderson, has publicly warned a man they say is their main suspect, and anyone assisting him.
Residents in Whangamomona say police have searched a property there with a metal detector and dug up part of a driveway.
Locals said the owner of the property, believed to be in his late 30s or early 40s, is a loner who lives in a barn house.
Whangamomona residents told the Herald police had asked them questions about the man, who has not been seen in the area for at least two weeks.
