"People are lighting stupid fires in windy and dry conditions. They just aren't paying attention to the conditions. If people show blatant stupidity we will do them for arson under the Crimes Act," Mr Myles said.
"There will now be no open fires at all. It's unsafe to do so and we are not expecting rain for a number of weeks so fire conditions are only going to get worse."
If smoke was spotted, a helicopter would immediately be deployed and the cost would be paid by those responsible for the fire.
On Wednesday, rural crews were involved in extinguishing five different fire sites at Towai, Parua Bay, Taupo Bay, Oruru and Whangaruru.
And crews remained at Maitai Bay where they were ensuring there were not more flare-ups.
Fireworks are suspected of igniting the fire that started on New Year's Eve.
The fires were spread across rural locations and had stretched resources.
Mr Myles worried if there was another major incident whether he would have enough firefighters to deal with it.
"We are running out of resources and some of these guys need a break.
"If we had a major fire we would probably struggle to get enough crew and that's when houses and people's lives are put at risk."
