After 15 years in Parliament, 14 different porfolios and a stint as Deputy Prime Minister, the MP for Upper Harbour Paula Bennett is exiting stage right at this year's election.

She told the party's new leader Todd Muller of her resignation this morning and says she is looking to work in the business world.

Following the leadership coup, Bennett declared herself all in with the party and keen to carry on.

Lisa Owens spoke to Paula Bennett and asked her what had changed.
