ACC Minister Judith Collins says she did not tell ACC chief executive Ralph Stewart to resign.
"I've simply said to Mr Stewart, was he sure of that decision and he was, and actually I feel quite sorry for Mr Stewart, he's had a tough time,'' she said.
Mr Stewart announced today he would stand down after just eight months in the role, becoming the latest senior ACC leader to go after the Bronwyn Pullar fiasco.
His resignation comes a day after ACC chairman John Judge was effectively forced out of his job and his deputy John McLiskie and another director Rob Campbell were also told they would not be reappointed.
Ms Collins admitted there was a culture problem within ACC but would not go as far as saying the chief executive was to blame.
