A car driving through long Kikuyu grass on a private property sparked a fire that spread over four hectares in Whangārei Heads.
Two appliances from the Whangārei Heads and Onerahi volunteer fire brigades were called to the fire on the corner of Taiharuru Rd and McRae Rd, in Taiharuru, around 1.40pm on Wednesday.
A helicopter and a Hikurangi Volunteer Fire Brigade tanker joined ground crews at the scene to help extinguish the blaze - a feat that took close to four hours.
Smoke billowed from the property and spread across the Taiharuru peninsula and as far as 8km away in Parua Bay.
