Police, the fire service and animal advocacy groups all say have fun on Guy Fawkes Day but act responsibly.
Police say people should respect other people and property, and be aware of the NZ Fire Service's guidelines for fireworks and any council bylaws which prevent the letting off of fireworks in certain public areas.
With dry windy conditions forecast, the Fire Service is asking people to take care and to be aware of areas with fire bans.
Federated Farmers is reminding people that fireworks can panic farm animals.
"Domestic dogs and cats might run for cover under the sofa. Cows, sheep, horses and other farm animals out in the paddocks don't have that option, and Guy Fawkes celebrations can panic them into bolting," says Katie Milne, a Federated Farmers National Board member.
The NZ Veterinary Association has highlighted two past fireworks cases where a panicked dog ran until the pads of its feet were worn bloody, and a horse that had to be euthanised after it spent a night trapped in a barbed wire fence.
As more urban areas push out into farmland, it's an issue those on the city/rural fringe need to think about, MS Milne says.
People are being advised to let their neighbours know if they're thinking about celebrating with fireworks and to check out organised displays as an alterative.
