A cyclist told police he was shot at from two vehicles near Omarama in Otago on Sunday night.
Community Constable Bruce Dow, of Oamaru, said the rider reported the incident on the 400m stretch of SH8 between Broken Hut Rd and the Omarama Stream Bridge.
The cyclist, in his early-60s, who declined to be named, said he had turned right from Broken Hut Rd on to SH8 towards Omarama at about 5.15pm, when two vehicles overtook him at speeds between 70-80km/h.
He said a passenger in the first vehicle - a black Mitsubishi Lancer - fired two shots, which were followed by a further shot from the same position within the trailing off-white Toyota Hiace van.
The man was taken aback as he heard the bullets fly past.
