State Highway 1 in Putaruru will be closed for the rest of the day after a truck and trailer carrying dangerous goods caught fire.
Fire crews from around the Lakes district were called to a "well-involved" truck fire about 2.10am opposite Z Petrol Station in the town centre, a Putaruru Volunteer Fire Brigade station officer said.
Three crews from Putaruru, a crew from Tirau, a hazmat control unit from Rotorua and a volunteer support officer from Turangi headed to the scene, he said.
The truck was carrying dangerous goods but the risk was quickly mitigated, he said.
