People are being asked not to gather food from the upper Waikato River until further notice.
Ngati Tahu – Ngati Whaoa Runanga Trust, supported by Te Arawa River Iwi Trust, has placed a rāhui from Te Waiheke o Huka (Huka Falls) to Pohaturoa (Atiamuri).
A rāhui is a management tool used to restrict use of an area to ensure the principles of kaitiakitanga (stewardship) are upheld and to protect the health and wellbeing of the community.
The action follows wastewater discharges into Lake Taupō following a major sewerage leak on July 2.
The Taupō District Council has been trying to control the wastewater leak with temporary measures but there have been two additional smaller spills.
