Money expert Mary Holm has a regular slot on Jesse Mulligan's show on RNZ National and a newspaper column. She's also the author of several books including "The Complete Kiwisaver". In her new book “Rich Enough - a Laid-back Guide for Every Kiwi”, Mary has easy-to-understand advice on reducing debt, buying a house and saving for retirement. She says research shows that once we have enough money to cover basics and have some fun, having more won't necessarily make us happier. Mary has an MBA in finance from the University of Chicago and is a director of the Financial Markets Authority and Financial Services Complaints Ltd.
