The hunt for the killer of roadworker George Taiaroa is widening with police questioning people as far away as Auckland.
Police are stopping traffic and questioning motorists in the hunt for Mr Taiaroa's killer a week after the 67-year-old road worker was gunned down on Tram Road, Kinleith, about 25km south of Tokoroa.
Police have checkpoints set up at different locations throughout the South Waikato as they seek more clues for the whereabouts of a blue Jeep Cherokee that was last seen on Link Road between Magakino and Benneydale not long after Mr Taiaroa was killed.
Detective Inspector Tim Anderson said police were seeking any information from people who may have seen the vehicle or any other information that may aid their inquiry.
He could not confirm how old the vehicle was but confirmed earlier reports that it was probably missing one of its number plates.
Mr Anderson said the search had widened with police questioning people throughout the Waikato, Bay of Plenty and as far away as Auckland.
But he was not discounting the possibility that the offender could be a local.
"It has the appearance that the offender was familiar with the road network here...as to where the person could be, that's anyone's guess."
Mr Anderson said the vehicle could be hidden locally and he asked people to be vigilant.
The eagle helicopter had been in use to help with the search for the vehicle.
"We had a lady call us the other day about a submerged blue vehicle," he said.
"We tracked it down and it was not the vehicle...this is a difficult place to search."
Mr Anderson said the enquiry was proving difficult and frustrating.
"There's no doubt about that, it's frustrating in the sense we haven't resolved it yet.
"We still think there's a number of opportunities for the public of the community of the greater North Island to help us resolve this."
Police had spoken with Mr Taiaroa's family to glean more about his background.
