Otago’s Water Plan is being reviewed by ORC. We are taking a staged approach to the review based on 'mountains-to-sea' catchment areas called Freshwater Management Units (FMUs). In Otago we have set five FMUs: Clutha/Mata-Au, Taieri, North Otago, Dunedin Coastal and Catlins. Due to the large size of the Clutha/Mata-Au FMU, it has been divided in to five sub-areas, called rohe, for a more tailored water management approach in these areas. One of these is the Manuherekia Rohe. 




The Manuherekia Rohe covers almost 3,000 square kilometres and is home to more than 6,000 people. It is a beautiful area, named for the river at its centre; the Manuherekia River.

As we go through this new FMU process, there may be some rules set for the Manuherekia Rohe that differ from other areas. This will be done in consultation with the local community to ensure that waterway management reflects local values and objectives.

We carry out monthly water quality testing as part of our State of the Environment (SOE) testing. Please note that SOE reports are based on five years of data. Read the SOE reports for:
