Search teams have been scouring areas of South Otago for a man missing since Wednesday.
Seventy-nine-year-old Ian Mathieson hasn't been seen since leaving his Lions' Club meeting in Clinton.
Waterways and previously searched areas have been re-examined today.
The search includes nine SAR teams, a water rescue team and a large team of Lions' Club members. A helicopter and search dogs were deployed to help with the search. A drone was also used to search the Kaihiku River through to the Clutha River.
The search will recommence in the morning.
