A complaint's been laid about Christchurch Council's claims that people are dying because of smoke from home fires.
John Hoare from the Association for Independent Research says Environment Canterbury's Air Plan states that 40 to 70 people a year die from the affects of air pollution.
But the council's advertisement quotes a higher figure from the DHB of 158 deaths annually.
Mr Hoare has complained to the Advertising Standards Authority.
“[It’s] another one of these minor environmental effects that, yes, it may have a small effect on health, but people are still dying basically from the things they normally die of.”
Dr Hoare says there needs to be a proper review of the science behind national environmental standards.
