Fireworks are believed to have sparked a blaze which ripped through scrub close to a Northland campground.
At its peak about 25 people were involved in trying to contain the blaze that covered 500sqm near Uretiti Beach Department of Conservation campsite on Sunday.
Ruakaka volunteer firefighter station officer Jeff D'Ath said crews were called about 6.50pm and he was in the first appliance that arrived.
"Initially we got called to smoke in scrub. But as we got out on to the highway and I saw the smoke I knew it was bigger than usual," Mr D'Ath said.
Another Ruakaka unit and the team from Waipu were called in to help.
