Police have confirmed their search of a rural property west of Rotorua today was linked to the fatal shooting of roadworker George Taiaroa last month.
A man in his 70s was arrested and charged with a firearms offence at the State Highway 5 property, but police say this was unrelated to the homicide investigation.
About eight police officers searched a paddock using specialist detectors, with some digging in one particular spot in the paddock.
A Rotorua Daily Post reporter said the driveway was blocked by security but there were marked and unmarked police cars and a van about 100m up the driveway.
The police dog unit was also at the property.
