Nelson police are looking for a white car, believed to be linked to a missing man.
Jim Schierny hasn't been seen or heard from since he left home on Sunday March 10.
Detective Senior Sergeant Wayne McCoy says all reported sightings of Mr Schierny, also known as Jim Tomas, have come up with nothing and his family are becoming increasingly concerned.
He says they believe he may have bought a car - a white 1990 Nissan Sentra with the registration plate PE 1334.
The vehicle was purchased in Motueka on March 9 by someone fitting Jim Schierny's description.
