Missing Blenheim man Colin Malcolm Ross' car has been found on the West Coast more than week after he disappeared in Blenheim.
The 53-year-old was last seen near a Blenheim fire station about 5pm on October 25.
Police said they had serious concerns for his welfare.
Ross' Toyota Rav 4 was found today near Karamea, at the end of the Heaphy Track, more than 100km north of Westport.
Police and Land Search and Research (LandSAR) have been searching nearby areas this evening.
More teams and a LandSAR dog unit will join the search effort tomorrow.
Police said in a statement that they still wanted to hear from anyone who had seen Ross' red or maroon vehicle, registration AJY133, in the last 10 days because this information could help them find him.
He was last seen in this vehicle on the day he went missing.
Greymouth Police also asked anyone who had seen Ross since his disappearance to contact them on 03 768 1600.
"Police have searched many areas in Marlborough and have been assisted by the public and family as well," said an update posted on the Blenheim police Facebook page yesterday.
Members of the public have also searched areas near Takaka, Golden Bay, 218km from Blenheim.
Marlborough police and other police in the South Island have been continuing enquiries into Ross' movements.
"We are following up on information that comes to hand as a result of our enquiries," Blenheim Police said on Facebook.
