Crews from Cromwell, Luggate, Wānaka, Dunstan and Tarras responded to the vegetation fire which took place off Cromwell-Luggate Rd.
Two helicopters were also sent from Wānaka and Dunedin, which helped speed the response process.
A Fire and Emergency New Zealand (Fenz) spokesman said they received multiple reports of a fire about 3.05pm.
The fire, in the Mt Pisa area, had burned through long grass and vineyards and had, at its peak, spread across 2ha.
No buildings were threatened by the blaze and no-one was injured.
Central Otago incident commander Bobby Lamont said yesterday they were still unsure what caused the fire, but a fire investigator was on the scene.
A few fires had started because of agriculture, such as mowing roadsides and ploughing, he said.
There was no certainty at the time that machinery was the cause of the fire, however Mr Lamont said they wanted people to have "general awareness around anything that could cause a spark".
He encouraged people to do activities such as mowing either earlier in the morning or in the evening when temperatures were not as high and to be careful when using appliances such as portable cooking devices.
Although caution was advised, he felt the region was prepared for the usual increase in fire risk this time of year.
"I’m not concerned. We do expect the potential for fires."
He also acknowledged many Central Otago communities had taken part in being careful as this was an issue most people were well aware of.
He encouraged people to check the Fenz website, www.checkitsalright.nz, for any updates on fire risks.
Meanwhile, smoke from a controlled and lawful burn-off south of Kingston drifted up Lake Wakatipu and was reported in and around Queenstown yesterday afternoon.
In a statement, a Fenz spokesman said the fire was in Southland, which was in an open fire season, and did not require a permit.
"If you are vulnerable to the impacts of smoke, you’re advised to close doors and windows, turn off your air conditioning and limit your exposure by staying indoors." — Additional reporting Ruby Shaw
