Powering New Zealand's Future

About Rua Kōhā

Rua Kōhā is a Māori word meaning "lightning on a mountain top" - a symbol of the power of the land, the wind and the sun and the potential for new energy developments to power the future.

We formed Rua Kōhā in 2025 to provide specialist services to the electricity sector. Based in Nelson, New Zealand, we work with clients across the regions. We're passionate about sharing our knowledge.

Our team has a deep understanding of the energy landscape and the challenges that our clients face. We are a team of experienced professionals who are passionate about the power infrastructure sector.

Our Services

• Site Identification and Land Access Negotiations

  We do investigations to confirm potential wind and pumped hydro sites and their generation potential, calculating costs associated with investigation, development, construction and operation phases. We work with clients to develop appropriate Investigation and Development agreements and negotiate these with landowners.

• Wind Resource Modelling

  Using advanced wind flow modelling software, we identify optimal site layouts considering turbine type, topography, and environmental constraints. We can generate preliminary models from existing data or establish regression models for targeted monitoring programmes.

• Pumped Hydro

  We identify sites with the head, storage and water a pumped hydro scheme needs, and model the cost of investigation, development, construction and operation. Layouts cover the reservoirs, waterways and powerhouse, held against topography, land access and environmental constraints, through to consenting and grid connection.

• Consenting for Energy Projects

  We manage the entire resource consent process, leading multidisciplinary teams to develop optimal project configurations, manage assessment of effects studies, and handle the consent application and hearing process.

• Design, Finance and Business Case Preparation

  We identify the most optimal engineering design within consent conditions, typically using a vanilla design with proven hardware, and a split contract approach to reduce overheads, we can build a comprehensive bankable business case and optimise to conditions that provide additional value.

• Project Management, Grid Connection and Commissioning

  We manage the entire project management process, if consenting has been completed, we can offer Construction managment and Commissioning services, such as Contract specifications and scopes, Design reviews, Quality Assurance and EIPC Commissioning Plans and Engineerging Methodologies.
