Zone management plans (ZMPs) are the primary tools for implementation of all river and catchment management activities the Waikato region. The region is divided up into zones, and each associated ZMP includes the following details:
This document provides an overview of river and catchment management within the region, and should be read alongside the ZMPs. The document outlines:

The Coromandel zone covers most of the Coromandel Peninsula, and has a total area of approximately 193,000 hectares. The zone includes all land within the Thames Coromandel District Council boundary, excluding those catchments that are incorporated within the Waihou-Piako zone including the Kauaeranga, Tararu and catchments flowing into Thames town. It also includes part of the Hauraki District Council area between Whangamata and Waihi.
The Lower Waikato zone consists of the Waikato River catchment between Ngaruawahia and the Tasman Sea. It covers an area of 283,757 hectares, which is 20 per cent of the total Waikato River catchment area.
The Central Waikato zone consists of the Waikato River catchment between Karapiro Dam and Ngaruawahia and has an area of 64,000 hectares. The zone represents 4.5 per cent of the total Waikato River catchment area. The zone is dominated by the Waikato River channel and associated rivers, streams and lakes and is unique in that it contains the major population centre for the region (Hamilton city) and contains two flood control assets (weirs).
The upper Waikato zone covers 436,000 hectares in the central North Island, stretching from the Kaingaroa plateau in the east to the Pureora and Rangitoto ranges in the west. Waikato Regional Council’s operational activities within this area are guided by the Upper Waikato Zone Plan which includes goals, strategies and actions for the zone for the next ten years. Ultimately, the plan is about contributing to improving the health of the upper Waikato catchment, including the protection and restoration of the health and wellbeing of the main stem of the upper Waikato River and its tributaries.
The Waihou Piako zone covers an area of approximately 3,734 km², and is dominated by the Waihou and Piako river systems. It includes the catchments of the Miranda Coast up as far as Kaiaua, the Waitakaruru River, the Piako River, the Waihou River, the Kauaeranga River, the Thames streams and the Tararu Stream. It includes all of the land that drains into the Firth of Thames from Kaiaua in the west to Tararu in the east, the major portion of which is the Hauraki Plains and Thames Valley catchments.
The Waipa Zone is one of five zones within the greater Waikato River catchment, and one of eight within the Waikato region. The zone has around 12% of the total land area within the Waikato region, 17% of the region’s population and contains around 20% of the region’s native vegetation.
The West Coast zone covers a large geographic area of 425,835 hectares, or approximately 17 per cent of the Waikato Region, stretching from Port Waikato in the north, to Mokau River in the south, and as far inland as Benneydale. Its rivers and streams drain a large number of catchments to the Tasman Sea. The zone encompasses three district councils; Waitomo, Otorohanga and Waikato; and overall has a low population base of less than 3 per cent of the region’s population.
