Firefighters were kept busy overnight with Guy Fawkes-related call-outs.
In what the Fire Service has labelled a "disappointing" result, call-outs on November 5 doubled from the same night last year.
The Fire Service confirmed its busiest areas were Waitemata, Counties and Christchurch.
Fire risk management national adviser Todd O'Donoghue said firefighters attended 117 firework-related incidents.
"Last year there were 56 calls - quite a disappointing result really," Mr O'Donoghue said.
"Most of the calls were relatively minor, just being trees, bushes and fences and that sort of thing."
In Auckland alone, firefighters attended more than 50 firework-related callouts by 11.30pm.
That included a garden shed fire in Mangere, about 9.30pm.
And early this morning, it took about two hours to quell a blaze in scrub under the Upper Harbour Bridge in Greenhithe, a fire spokeswoman said.
Another Auckland blaze took hold of a scrub in Mt Wellington.
"There were a couple of near misses," Mr O'Donoghue said.
"[There was] a firework under a house in New Plymouth and that started a fire. That was put out by the people there."
In Wanaka, trees and a fence near a house caught alight, but firefighters put it out in time.
"There was also some disappointing behaviour with people firing fireworks out of cars, which the police have followed up."
Mr O'Donoghue said callouts for earlier this week were down compared with last year, possibly due to poor weather that had cleared by last night.
He reminded people planning to let off fireworks over the weekend to do so safely, ensure someone sober is around to do it, and make sure there is enough clear space.
"The number of calls we had last night occupied our firefighters, who could be required at any time for other emergencies," Mr O'Donoghue said.
"As well as the danger aspect, it can also put other people at risk when our resources are stretched."
Mr O'Donoghue said firefighters also attended non-Guy Fawkes incidents last night, including house fires.
In Christchurch, a police spokesman said there were several public disorder incidents after the fireworks display at New Brighton pier.
