Tairua Harbour and Catchment Management Plan

Report: TR 2011/40

Author: E O'Donnell

Abstract

The intention of this plan is to provide an assessment of current pressures and issues in the Tairua Harbour and catchment and provide a practical strategy to alleviate these. This plan will also action those matters identified in the Coromandel Peninsula Blueprint (both district-wide and local area blueprint matters) that fall within its scope.

Comparisons will be made over time as a result of recommended works to demonstrate change. More detailed site specific plans will be developed in conjunction with landowners and land managers for specific works and issues on their properties.

This plan is non-statutory but it will have the capacity to inform and support statutory documents such as district and regional plans. Its success relies on the uptake and goodwill of landowners and land managers within the catchment as well as the support
of key agencies.
