Veteran National MP and former Cabinet minister Judith Collins will lift the lid on her time in Government in a tell-all book which details some of the most trying times of her political career.
Although she said it was not her purpose to embarrass people, embarrassment would be "inevitable for some".
She won't say who those people would be, only that "they know who they are".
"I have so many really good stories, I have some great records," she told the Herald.
Having "good records" is a phrase she repeated a number of times when talking to the Herald and to the AM Show this morning.
