Please note, ORC uses the Kāi Tahu spelling of Manuherekia.
Under national legislation, regional councils must manage waterways at an appropriate scale for setting freshwater objectives and limits.
We have set five Freshwater Management Units (FMUs) and divided the Clutha Mata-Au FMU into five rohe (areas). One of these is the Manuherekia Rohe, which is based on the catchment area of the Manuherekia River.
The Manuherekia Rohe sits between the Dunstan Range to the west, the St Bathans Range to the north, the Hawkdun Range and Rough Ridge to the east and the Knobby Range to the South. The Manuherekia River, the rohe’s main water body of the rohe, flows for 85 km in a south-west direction towards Alexandra where it joins the Clutha Mata-Au River. The rohe stretches over approximately 3,000 km2.
The climate of the Manuherekia Rohe is semi-arid, characterised by cold winters, warm, dry summers and low rainfall. The area is dominated by pasture grasslands on the flat and gently sloping land, while tussock grasslands are common in the high country.
The lower end of the rohe has the urban area of Alexandra, and the settlements of Omakau and Ophir are small but growing.
The Manuherekia Rohe is combined with the Roxburgh Rohe and the northern part of the Taieri Rohe when considering socio-economic information. These communities have close economic ties – for example, many residents live in one area and work or spend time in the others. The three areas combined are referred to as the ‘Inland’.
In 2018, the area was home to around 13,000 residents (6% of Otago’s population),an increase of 15% from 2006. The economy of this area depends on the water-reliant agriculture sector (which provides for one in five jobs) and tourism-related industries (15% of all jobs). Administrative services (13%) is the third largest sector in the area, with the sub-category of employment services providing 10% of all jobs. Together, these industries account for around half of the employment in the ‘Inland’ area.
It is important to understand Māori history and the Māori economy when developing policy and assessing its impact. Pre-European Māori history shapes today’ Aotearoa, and the Māori economy is integral to the national economic system. A report prepared by Aukaha, with support from ORC, provides a Kāi Tahu assessment of the socio-economic impacts of freshwater management in Otago.

This study is designed to estimate the economic impacts associated with probable changes to farm operations due to proposed policy options for water management in the Manuherekia catchment.
