What We Do

At Te Ngahere, we deliver practical, end-to-end ecological restoration solutions that protect, restore, and enhance New Zealand’s natural environments. Working with councils, government agencies, iwi, private landowners, community groups, and commercial organisations throughout the North Island, we combine technical expertise with practical field experience to deliver projects that achieve lasting environmental outcomes.

From ecological planning and project management through to on-the-ground implementation, monitoring, reporting, and long-term maintenance, our experienced team provides a complete restoration service under one roof.

Our capabilities include:

  • Ecological restoration planning and project management
  • Pest plant and aquatic weed control
  • Pest animal control and remote trapping networks
  • Offshore island restoration and biosecurity programmes
  • Biodiversity monitoring and ecological surveillance
  • Riparian, wetland, freshwater and native forest restoration
  • Native planting and revegetation
  • Biosecurity operations and invasive species management
  • Environmental monitoring, reporting and long-term maintenance


Our teams work across an incredibly diverse range of environments, from urban reserves and regional parks to remote back-country, offshore islands, working farms, wetlands, rivers, lakes, coastal margins, native forests, and large private landholdings. Whether establishing remote trapping networks, undertaking aquatic weed control from boats, restoring riparian corridors, protecting threatened species, or delivering large-scale restoration programmes, we have the experience, specialist equipment, and operational systems to work safely and effectively in some of New Zealand’s most challenging environments.

No matter the size or complexity of the project, our commitment remains the same—to provide practical, high-quality ecological restoration solutions that deliver measurable conservation outcomes. By combining sound ecological knowledge with experienced project management and skilled field teams, we help our clients restore biodiversity, strengthen ecosystem resilience, and create lasting environmental benefits for future generations.

Our teams are experienced working safely in sensitive freshwater environments while minimising impacts on native species and water quality.

Biodiversity Monitoring & Ecological Surveys

Good restoration relies on good information.

We undertake ecological monitoring and surveys to establish baselines, assess project performance, and inform adaptive management.

Services include:

  • Pest animal monitoring
  • Trail camera programmes
  • Tracking tunnel monitoring
  • Residual Trap Catch Index (RTCI)
  • Residual Trap Index (RTI)
  • Bird monitoring
  • Freshwater surveys

Our monitoring programmes provide reliable data that helps clients measure ecological outcomes over time.

Biosecurity & Surveillance

Early detection is critical to successful biosecurity management.

Te Ngahere has extensive experience supporting regional and national biosecurity programmes, undertaking surveillance, delimiting surveys, invasive species responses, and ongoing monitoring.

Our teams have worked across a range of biosecurity responses and are experienced operating within coordinated incident management frameworks, delivering reliable field capability when rapid response is required.

Restoration Planning & Project Management

Successful restoration starts with good planning.

Our project managers work closely with clients to develop practical, achievable restoration programmes tailored to each site’s ecological values and objectives.

Our planning services include:

  • Ecological restoration planning
  • Riparian restoration plans
  • Wetland restoration plans
  • Planting design
  • Pest management plans
  • Restoration staging
  • Budget development
  • Operational planning
  • Contractor management
  • Monitoring and reporting


Because we both design and deliver restoration projects, our plans are practical, realistic, and built around what works in the field.

Long-Term Maintenance

Restoration doesn’t finish once the initial works are complete.

We provide ongoing maintenance programmes that protect previous investment and allow restoration sites to continue developing over time.

This includes:

  • Weed maintenance
  • Pest animal maintenance
  • Infill planting
  • Plant release
  • Monitoring
  • Adaptive management
  • Annual reporting


Our long-term partnerships help ensure restoration projects continue to deliver ecological benefits for years to come.
