According to the New Zealand Herald, “Economist and fund manager Gareth Morgan, who is a member of the Tax Working Group, has proposed a radical tax restructure to the group’s final public conference that would impose a Comprehensive Capital Tax (CCT) on all land, buildings, plant and equipment to raise NZ$19 billion. This money would then be used to create a flat income tax rate of 25% on all corporate, personal and trust income. It would also be used to provide each adult with a NZ$10,000 guaranteed minimum income to replace all benefits”
