Growers have been left fuming after a Waikato Regional Council decision to withdraw a giant section of the region from its Healthy Rivers plan.
The proposal is designed to clean up the Waikato and Waipa Rivers to make them swimmable in about 80 years.
But on Monday, WRC announced it was withdrawing 120,000 hectares, or 11 per cent of the total land included, from the reforms over a lack of consultation with local iwi.
The area withdrawn covers Te Kauwhata, Meremere, Mercer, Pokeno, Waeranga and Maramarua, along with parts of the Waikato River and a series of wetlands, rivers and streams.
Council chief executive Vaughan Payne said the area could be re-incorporated back into the main plan next year after consultation with Hauraki iwi.
