A South Auckland health educator has had his complaint against talkback host Michael Laws partially upheld by the Broadcasting Standards Authority, Waatea News reports.
Mr Laws told his listeners Boyd Broughton was telling clients that smoking is a Pakeha plot to kill Maori.
The authority says that's not what Mr Broughton's email actually said, and cannot be regarded as a fair comment.
Mr Broughton says he emailed the Whanganui mayor about the spelling of the city, and was surprised when Mr Laws replied with an email about his Maori anti-smoking work.
"The main good thing that came from it was that on the day most people rang up just to talk about smoking and tobacco, rather than to enlarge the controversy he was trying to create," he told Waatea News.
Mr Broughton says he doesn't regret taking on the high profile host, but it may have been a mistake to exchange emails with Michael Laws at 11 o'clock at night.
