Whanganui firefighters are asking people in the region to be wary of conditions when lighting fires, after crews spent four hours extinguishing a vegetation fire near Kai Iwi.
A Fire & Emergency New Zealand spokesperson said one Whanganui Fire Station appliance and a tanker responded to the vegetation fire off State Highway 3 at around 2.45pm on Thursday.
Later two rural fire crews responded to the fire and a volunteer support vehicle was brought in to assist with traffic control.
The fire spread across an area of about 100m by 300m on a bluff overlooking the highway and crews were at the site until around 6pm.
Whanganui Fire Station station officer Gerard Packard was at the scene and said crews had the fire under control in about 30 minutes.
