Motorists are being urged to take care on State Highway 1 north of Kaitaia due to a breakout of the Kaimaumau fire.
As of 4.45pm today strong winds and high temperatures caused the fire to flare up near the highway about 2km north of Big Flat Rd, between Waiharara and Houhora.
Initial reports were that flames had jumped the road and vegetation was burning on both sides of the highway.
However, a reporter at the scene said flames were about 100m from the road.
