Firefighters have contained a blaze that left two people suffering smoke inhalation and forced the evacuation of four streets in the Auckland suburb of Clendon Park.
Jody Brown, who lived on a street bordering the reserve, said the smoke swept through the neighbourhood.
"We could see smoke for miles."
She lived far enough away to avoid evacuation, but said she was still worried as the area is so dry at the moment.
Northern fire communications shift manager Jaron Phillips said firefighters remained at the scene to dampen down hot spots.
One person was taken to hospital after suffering severe smoke inhalation that brought on an asthma attack, he said.
Police said a second person had also been treated for smoke inhalation.
About 40 firefighters battled the blaze, which forced the evacuation of dozens of homes in the South Auckland suburb, he said.
Firefighters were alerted to the scrub fire in a reserve by the residential area about 2.20pm.
Police closed Bellville Dr, Bill Phillip Pl, Eloise Pl and Burundi Ave due to smoke and warned people to stay clear of the area.
The fire covered about 1000 square metres at one point.
