Fireworks have sparked an average of 160 fires a year over the past decade, with numbers rising in the past two years, Fire and Emergency New Zealand said.

Ahead of Guy Fawkes, FENZ is urging people to choose a clear space, check conditions and leave fireworks unlit if it is windy.

Fire and Emergency acting national manager community readiness and recovery Tom Ronaldson said recent blazes had highlighted the danger.

“Several large fires in recent weeks have already shown how easily fires can start and spread in windy conditions,” he said.

“With parts of the country already starting to see El Niño conditions bringing warm and dry weather, it’s particularly important now and through the summer months that people take care if they’re planning to set off fireworks.”

Ronaldson said anyone choosing to light fireworks was responsible for making sure they did not cause a fire.

“It is important people point them up to the sky, well away from anything flammable, and that they have water on hand in case it’s needed.”

People should keep a large bucket of water or a hose nearby and ensure fireworks cannot land in buildings, vegetation or other flammable material.

FENZ encouraged people to visit checkitsalright.nz for weather conditions, local fire restrictions and guidance on using fireworks safely.

Many public spaces have year-round fireworks bans, and people should check with their local council before lighting them at beaches or parks.

Neighbours should also be warned about planned fireworks, particularly those with pets or livestock.

Used fireworks should be soaked in water before being thrown away.
