This week for Green Desk Mitchell had a korero with Environment Minister David Parker about the new National Policy Statement for Highly Productive Land. The new Policy statement aims to tighten the management on highly productive land under the Resource Management Act in order to protect these areas of arable land from inappropriate subdivision and urban development. They discuss what will be included in the NPS and how it will be implemented at ground level. Mitch begins by asking David for a bit of context on the issue, and why there is a necessity for such legislation.
