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.
