Negative gearing: Tax-dodge or legitimate practice?

Earlier this year, Revenue Minister Judith Collins announced a planned crackdown on tax-dodging by multinational corporations. Under the plan, various loopholes are to be closed, in order to make it harder for untaxed money to be moved outside of New Zealand. However, there are plenty of other ways for people to reduce their tax bill, such as negative gearing, which went unmentioned by Minister Collins. To gain a greater understanding of what negative gearing is, producer Ben spoke to Deborah Russel, a senior lecturer on taxation for Massey University and electoral candidate for the Labour party.
