Mrs Southey said people must immediately stop lighting incinerators or bonfires and further help the situation by not burning treated or wet wood in their woodburners. "If they continue to do so then they risk spoiling it for everyone.
"There could be restrictions put on installing woodburners and the Ministry of the Environment could well increase the performance limits on them, which would lead to a lot of existing woodburners becoming non-compliant," Mrs Southey said.
"We are facing a crisis here, there are only so many times you can breach air quality limits in a year without something being done about it."
Air quality in Masterton is monitored by Greater Wellington Regional Council as a requirement under the Clean Air Act.
Mrs Southey said the council has put a lot of effort into educating people how to avoid causing pollution, particular in regards to what wood to burn.
"We do not want to come down heavy-handed on people but I am saying to them, please help the situation by obeying the rules."
