Children playing with a lighter started a fire that threatened nearby homes in Christchurch's Port Hills today.
Eight fire engines and a helicopter fought the large scrub fire in Huntsbury which started just before 1pm.
Firefighters managed to get the fire under control by 3pm but one fire crew remained on into the evening dampening down hot spots.
A Fire Service spokeswoman said that at one stage the blaze threatened two homes.
Fire safety officer Graham Davies said the children had found the cigarette lighter and began playing with it. He believed they had no intention of deliberately starting the fire.
