Gale force winds hampered firefighters as they contained an undergrowth fire in the Purunui Forest.
The blaze was sparked after high winds brought down power lines in the forest.
About 50 firefighters from urban and rural fire crews tackled the fire in the forest bordering Castlepoint Rd, about 2km northeast of Langdale Rd yesterday.
Smoke could be seen billowing above the forest, owned by Anglican School Trust, from part way along Langdale Rd.
Masterton station officer Doug Flowerday said a passing motorist reported the fire about midday. When the Times-Age arrived 4ha of undergrowth were being contained by the firefighters. A Carterton water tanker was also on site.
