Central Lakes Area Office senior station officer Stuart Bootten said there had been a marked improvement in public responsibility around fireworks between 2010 and last year.
Last year the fire service recorded six firework-related vegetation fires between November 1 and 10, down from two firework-related property fires and 17 vegetation fires over the same period in 2010.
However he said all stations were still on high alert and volunteers were opting to man their stations in the Guy Fawkes season.
"We're not comfortable with it yet, we know that the incidents of fire are reducing but we've got a wee way to go until we can feel comfortable and not have to put extra resources in place just in case it does happen.
"There is still a need to call the fire service, people are right to react if there is a fire.
"Don't think they've got it out themselves, we've got some experts on our fire trucks to make sure it's out."
The New Zealand Fire Service is encouraging people to make the most of public Guy Fawkes firework displays.
Risk Management Assistant National Commander Rob Saunders said there had been a dramatic reduction in firework-related emergency calls since 2000, when a law change saw the minimum purchase age raised from 14 to 18 and sales restricted to four days up to and including November 5.
Previously sales were permitted for 10 days.
He believed a growing number of people chose to attend large, public displays rather than buying their own fireworks.
The New Zealand Veterinary Association (NZVA) is advising pet owners to prepare pets psychologically and physically for Guy Fawkes celebrations.
