Simon Bridges announces 'intensely personal' memoir National Identity, on masculinity, race and fitting in

Former Opposition leader Simon Bridges says he will release an "intensely personal" memoir this year.

In a post to Twitter on Monday afternoon, the National MP unveiled the title, cover and release date of the book - and gave a hint at what would-be readers should expect from it.

"I'm excited to share with you about my new book," he wrote.

"An open, honest and at times intensely personal memoir about race, fatherhood, marriage, masculinity, fitting in, and the things that shape our national character."

The memoir - entitled National Identity: Confessions of an Outsider - will be released on Wednesday, August 18.

While Bridges is best-known as a politician - and the book will be of particular interest to those who want the inside word on his brutal ousting as National leader last year - the Tauranga MP says the book will not be political.

Bridges isn't the first National politician to pen a memoir in recent years. Current leader Judith Collins also released an autobiography last year, Pull No Punches, about her life and career in Parliament.

Last month, Bridges was repeatedly forced to downplay talk he's keen to make another push at leading the National Party alongside MP Christopher Luxon. After a series of vague answers, Collins told media to "let them get on with the job".

In late April, Bridges finally gave a firm response to questions about the leadership, telling The AM Show has no desire to take back what he calls "the worst job in New Zealand".
