The Otago Daily Times obtained a copy of a letter from Grey Power's Zone 7 (Otago and Southland) director Dick Stark, of Gore, which was sent to the North Otago association.
In the letter, Mr Stark said he had been contacted by representatives of the North Otago association's committee informing them that there had "surfaced dissatisfaction" over Mr Bradshaw's leadership.
"The issues given to me are that Mr Bradshaw [sic] actions always pertain to his own opinions, and that although for some time committee members have tried to converse with him to discuss their concerns, he will not listen to them, and always advocates that it is his word only that must be the dominant and only decision on all issues," the letter read.
Mr Stark was informed that Mr Bradshaw had not been interested in the communications sent to associations.
"Grey Power, as New Zealand's largest advocacy group, cannot have the disharmony that ill-informed communication brings about, and this in today's climate just cannot be tolerated," he said.
When contacted yesterday, Mr Bradshaw said the local Grey Power committee and Mr Stark wanted "rid" of him because he spoke his mind.
"I ask questions and I don't let rubbish carry on."
Mr Bradshaw, who said there were "untruths" in Mr Stark's letter, said he planned to resign at the annual meeting on May 6.
"They can shove it. I didn't retire to put up with this rubbish.
"If they don't want me, they don't want me."
He has been president "on and off" for two years.
He walked out about 18 months ago but was "begged" to come back, he said.
While the number of members locally had dropped a few years ago, they had since been built back up.
"I thought we were doing everything good," he said.
When contacted yesterday, Mr Stark, who emphasised he had not supplied the letter to the media, said he stood by his comments in the letter "100%".
Mr Bradshaw's inexperience had been coming through and he had been getting messages from people concerned about his leadership.
