Report: TR 2013/34

Author: Sandra Barns and Justine Young

Abstract

In 2011, Waikato Regional Plan Variation 5 – Lake Taupo Catchment (Variation 5) became operative, providing long term protection of water quality in Lake Taupo, New Zealand’s largest lake. It was the culmination of more than ten years of policy development by the Waikato Regional Council (the council), involving consultation with affected landowners and the Taupo community, technical investigations, formal submissions and hearings processes, and Environment Court. The objectives of Variation 5 can be summarised as:

  • maintaining the current water quality of Lake Taupo
  • managing adverse effects of land use activities to Lake Taupo water quality
  • avoiding near shore effects from wastewater
  • minimising economic costs and mitigating social and cultural effects.
