A number of farm buildings and an empty house have been damaged in a fire in the South Island's Mackenzie District.
The blaze started around 4am on Friday near Burke's Pass, between Fairlie and Tekapo, and now covers around 100 hectares or rural land.
It is contained in around 60 percent of the perimeter, with fire crews working to protect Transpower transmission lines.
The Mackenzie District Council Emergency Operations Centre said Fire and Emergency NZ were using "significant resources" to battle the blaze, including five helicopters.
"There is no current threat to dwellings," the council said.
One landowner was affected but no evacuations were planned.
Some stock had been lost in the blaze, the council said.
"This is an evolving incident and we will advise if the situation changes."
