Anyone whose fireworks start a blaze tonight will have to pay to put it out, Far North fire bosses say.
The warning comes amid an unusually dry spring and after Kaitaia firefighters were called to two fireworks-related blazes over the weekend.
A fire ban already in force in the Far North - thought to be the earliest on record - could also put a dampener on any bonfire parties planned tonight. A fire ban does not yet apply in Whangarei or Kaipara.
Principal rural fire officer Myles Taylor said anyone in the rural Far North would need a permit to light a bonfire on Guy Fawkes night and should take extreme caution with fireworks.
Recent rain had done little to bring down the fire risk.
