Fire crews expect to be at the scene of a large blaze in Canterbury until the end of the week.
The Waipara forestry fire was first reported on Thursday.
About 75 firefighters worked to tackle hot spots and consolidate control lines at the fire ground today.
“Fire crews expect to stay at the fire ground for the rest of the week,” a Fire and Emergency NZ spokesperson said.
Incident Commander Brian Keown added that 10mm of rain in the last 24 hours has helped.
“But the fire isn’t extinguished, and the rain has made surfaces slippery and difficult for firefighters and vehicles,” he said.
“Overnight our drone identified hotspots and mapped the fire area, which is approximately 108 hectares.”
There was “deep seated burning” at two sites, he added.
“These two sites are producing a lot of the visible smoke, which will reduce as work is completed.”
