Helicopters and firefighters are back at the Black Jack fire on the Coromandel Peninsula this morning.
Firefighters battled strong winds and steep terrain to fight the fire in Kūaotunu after it broke out on Saturday.
It was under control by Sunday.
The fire had not grown overnight, but while conditions were calm on Monday morning, the winds were forecast to pick up during the day.
Fire and Emergency Incident Controller Shane Bromley said three helicopters would provide an air attack that would focus on the western flank of the fire on steep and inaccessible terrain.
Four ground crews would continue work mopping up hotspots on the eastern and southern fronts, he said.
"Black Jack Road will be under traffic management today, with managed convoys in and out providing access for residents and those with essential business in the area."
The walking track in the area remained closed.
