Wai Connection – Tatai Ki Te Wai
Mountains to Sea Conservation Trust

Empowering Communities with Integrated Science and Engagement Expertise
At EOS Ecology, we believe that empowering communities to protect their local waterways requires more than just information; it demands an integrated approach that combines science, technology, design, and hands-on support. That’s why, as a lead partner with the Mountains to Sea Conservation Trust on the ‘Wai Connection – Tatai Ki Te Wai’ project, our multidisciplinary team has harnessed expertise across freshwater science, GIS, science interpretation, and community engagement to empower groups across Aotearoa. This ambitious initiative, supported by the Ministry for the Environment’s Essential Freshwater Fund, connects councils, community/catchment groups, and hapū/iwi in addressing local catchment challenges – with EOS Ecology’s integrated services providing essential knowledge and tools to inspire community-led action toward improved freshwater values.

A National Strategy with Local Impact: Unified Resources and Support
From building ‘Wai Connection’s brand identity to developing key resources, EOS Ecology’s approach has been instrumental in ensuring the project’s tools are accessible, adaptable, and relevant. We have created a knowledge hub that includes a secure Provider Portal with GIS-based maps and dashboards, enabling regional Provider Organisations (POs) to connect communities to data specific to their areas. This portal also features a suite of templates for event resources, educational materials, and interactive maps, empowering each PO to tailor their engagement efforts effectively. Through our design, GIS, and communication skills, we delivered a cohesive set of resources that not only supports local efforts but also strengthens nationwide community connections for impactful freshwater management.

Transforming Data into Community-Driven Action with GIS Expertise
A standout element of our work on ‘Wai Connection’ is the Focus Catchment Map Series (FCMS) – a GIS-driven tool designed by EOS Ecology to make complex data accessible and actionable for communities. Leveraging our technical and science interpretation expertise, we have compiled national and regional datasets into visual maps that build a cohesive picture of the known state of each focus catchment, and connecting in with national goals around freshwater. These maps provide communities with the insights needed to make informed decisions and are readily accessible on the ‘Wai Connection’ website. Our integrated approach to GIS solutions and science communication turns data into a practical, user-friendly resource that enhances community-led environmental stewardship.

Supporting Communities through Direct Engagement and Regional Capacity-Building
As the Provider Organisation for Waitaha/Canterbury, the hands-on support of our Regional Manager and three Catchment Coordinators has been pivotal in building catchment group capacity. Our engagement team is bolstered by our integrated team of scientists, GIS specialists, science interpreters, and engagement professionals ensuring that each catchment receives tailored support—from training on freshwater monitoring and restoration planning to organizing events and securing funding. Through collaborative hui, field surveys, technical guidance, and oversight via a Regional Advisory Group, we’ve equipped local groups with the confidence, skills, and connections to take ownership of their environmental initiatives, bridging the gap between local needs and broader regional strategies.

Our commitment to community-led environmental health drives us to continuously adapt and expand the support we provide, exemplified by our work on ‘Wai Connection’. Together with our partners, we are building a legacy of informed, empowered communities working toward a sustainable future for Aotearoa’s waterways.

Protecting Wellington’s Waterways: Integrated Catchment Management
Wellington Water Limited

A key stage of Wellington Water Limited’s Integrated Catchment Management Plan (ICMP) process required detailed plans to be developed for five urban catchments across Wellington to address stormwater challenges and protect the local environment. The objective was to meet required service levels for the catchment’s stormwater system, identify solutions to minimise catchment issues, and establish preferred methods for sustainable management.

A core component of this stage involved assessing the potential impacts of stormwater on terrestrial and freshwater ecosystems. EOS Ecology provided essential expertise to answering this by conducting a high-level ecological assessment of these five urban catchments. Collaborating with local experts, utilising existing information, and conducting on-site evaluations, our scientists identified the conditions of streams, wetlands, and critical terrestrial features within the catchments, which established an ecological baseline for future assessments.

Our work highlighted both the existing natural and modified ecological values, giving insight into how land development and stormwater management have influenced these areas. EOS Ecology’s recommendations included protecting specific natural features for their ecosystem values, enhancing ecological corridors to improve resilience against stormwater impacts, and targeting critical data gaps to support decision-making. By building a foundation for informed, sustainable management, this phase also established a plan for ongoing monitoring to address any remaining knowledge gaps and ensure continued protection of ecological values. Through this comprehensive assessment, we have been able to offer invaluable recommendations to guide Wellington Water’s ongoing efforts to protect and enhance Wellington’s urban waterways, supporting healthier and more resilient ecosystems for the future.
