Fire and Emergency New Zealand (Fenz) said the fires — at Nenthorn, about 30km from Middlemarch, and in the Earthquakes area near Duntroon — were reported shortly after midnight yesterday.
By 5pm yesterday, the fires were fully contained and crews were working to dampen down hotspots,
Three households near the Nenthorn blaze self-evacuated overnight and were unable to return for much of yesterday.
Fenz incident controller Bobby Lamont yesterday said both fires were contained, but work to consolidate the perimeters and extinguish hotspots was ongoing.
No dwellings have been lost in either fire but a small number of farm buildings were destroyed or damaged at Nenthorn.
The Nenthorn fire was mapped at 78ha of farmland during aerial reconnaissance yesterday morning.
Due to gale-force winds, flames came close to a farmhouse but fire crews were able to save it.
Mr Lamont said the Middlemarch crew, which was first on the scene at Nenthorn, did "an amazing job" to protect a house from the flames.
Crews from six other volunteer brigades also responded, as well as the command unit from Dunedin.
Nenthorn, Ramrock and Butter and Egg Rds were all closed for most of the day and a fire investigator would investigate the cause of the blaze.
A second fire at Earthquakes, near Duntroon, burnt about 30ha of conservation land.
By 5pm yesterday, the fire was under control and all crews had left.
Incident controller Jason Sarich said crews had worked hard in challenging conditions, which included gale-force winds overnight.
"The wind dropped around 7am this morning and crews were able to get on top of it pretty quickly."
About 30 firefighters and two helicopters attended the fire and were joined by two crews of firefighters from the Department of Conservation.
Doc crews will patrol and monitor the fireground for the next few days.
