Otago Peninsula farmers have been asked to check beaches for any signs of a missing Dunedin businessman.
Kevin Zhang (50), a real estate agent and business owner, was reported missing last Tuesday. His white Toyota Starlet was discovered near the Karetai track the same morning.
Senior Constable Lox Kellas, of Portobello, said local farmers had been asked to check beaches daily, alongside regular police checks.
Checks with Immigration New Zealand showed Mr Zhang had not left the country, and his bank accounts remained untouched.
About 100 searchers, including dozens of people from the local Chinese community, searched along the Otago coastline on Saturday morning.
Police will review the search on Monday.
