A bush fire crossed State Highway 25, leading to closure the road between Whangamata and Hikuai for several hours.
The blaze swept over the highway at Toko Road near Onemana.
Coromandel District Council mayor Sandra Goudie said local rural fire fighters and two helicopters bought the blaze under control.
Goudie understood the fire originated from a hedge on the side of the ride, but the cause was unknown.
She was not aware of any dwellings being at risk and said hot spots were being dampened down.
"My biggest concern would be the wind fanning the flame and going towards any other forested or semi forested blocks. It's still pretty dry."
There were strong winds, and the area had not had much rainfall over winter, Goudie said.
The road was reopened shortly before 1pm.
Until then motorists had been asked to avoid the area, delay travel, or use a detour on State Highway 25A, State Highway 26 and State Highway 2.
