The Kerikeri Fire Brigade sent two appliances to a large, illegal rubbish fire at Oromahoe on Tuesday afternoon.
The blaze is understood to have measured about 10m by 20m and had started spreading into grass.
Fire and Emergency NZ sent three officers to the scene but all residents in the area denied having lit it and blamed their neighbours instead.
This season's fire restrictions were introduced on November 26 and raised to a total ban on January 13.
Major fires during the ban so far include one at Paihia on March 1 which threatened 10 homes and forced half a dozen to be evacuated. The investigation is continuing but a beach campfire is thought to have been the cause.
