Police are appealing for sightings of two cars in the search for a South Taranaki man who has been missing for more than three weeks.
Aaron Roigard has not been seen since he left an Opunake house on 2 June after a disagreement with a relative.
Detective Senior Sergeant Blair Burnett said extensive searches of farms and along the coast had failed to turn up any sign of him.
Mr Burnett said the police had serious concerns for Mr Roigard but he would not say what they believed might have happened to him.
Police were interested in sightings of a silver Mitsubishi Lancer and a white Suzuki Swift in the Opunake area on 2 June.
