Fenz Otago district manager Phil Marsh said the ban would start at 8am today and continue until further notice.
It meant no outdoor fires were allowed in the district, and all fire permits had now been revoked.
"Even if we do get some rain this week, it won’t have much impact on our dried-out tussock and grasslands," he said.
"If a wildfire gets going in this environment, and there’s even a bit of wind, it can be really difficult to bring under control.
"We’ve made this decision to prohibit fires to protect the people, property and environment of the Lakes and Glendhu Bluffs areas."
Mr Marsh urged people to think about the possible fire risk involved in activities such as mowing, using power tools, or parking vehicles on long, dry grass.
"When planning your activities, check the forecast fire danger for that day — consider working in the morning, and avoid hot, dry and windy days altogether.
"We’ve had several unwanted vegetation fires in Central Otago over the last couple of weeks, caused by people operating machinery."
However, he said a fire in Gibbston last week appeared to have been caused by light which was magnified through a glass bottle on to dry grass.
"If you’re not sure what the fire risk and restrictions are in your location, go to checkitsalright.nz.
"Enter your address and follow the guidance provided — this is the best way to help us prevent fires in Otago this summer."
