Fire Service southern communications shift manager Andrew Norris said several units attended the fire 2km from Waipahi about 4pm.
The blaze was extinguished, but a fire crew was to remain on site overnight to monitor the area.
The second fire, about 2km north of Balclutha about 6.20pm in a layby, was being treated as suspicious.
The road was briefly closed by police until the fire was put out, by a single unit and one tanker, he said.
