Foreword Aotearoa New Zealand’s water infrastructure, including stormwater, wastewater, and drinking water, is foundational to the health, prosperity, and resilience of our communities and economy. Yet the sector faces increasing pressures: decades of underinvestment, urgent climate adaptation needs, more demanding regulation, and communities calling for greater value, reliability, and environmental stewardship.

Addressing these challenges demands sustained investment, innovation, and collective effort. Projections indicate up to 24% growth in water sector project spending and $47.9b investment in new water infrastructure over the next 10 years [1]. International benchmarks show that research and development are proven catalysts for sector growth, resilience, and efficiency: private R&D returns average at least 14%, while public research delivers even higher social and economic benefits[2]. In the water sector, benefits are measurable and significant - OECD evaluations note that every dollar invested in research typically delivers five to tenfold returns, and studies from Australia demonstrating that every research dollar can deliver up to $13 in quantifiable benefits[3]. In New Zealand and globally, evidence confirms that research drives better performance, resilience, and cost efficiency.

Collaboration and alignment are the keys to impact. This Research Action Plan is deeply rooted in extensive consultation; over 200 sector representatives, from diverse backgrounds, have contributed their insights and priorities. The result is a genuinely sector-driven agenda that supports national and regional strategic objectives, aligns with international best practices, and ensures research funding is targeted to areas of highest need and value.

Critically, the report’s findings have practical application for a wide audience: Funders and investors can use the priority areas to identify where resources will deliver greatest impact and align with sector transformation strategies.

Researchers can leverage the evidence and insights to develop proposals with clear sector relevance and achieve better partnership with end-users.

The wider sector benefits from shared knowledge, innovation, and an agreed set of challenges and research targets, ensuring a united response to future demands.

This report, supported by research commissioned by the Water Services Managers Group, provides evidence-based direction to help navigate the sector’s most pressing challenges. The expertise, passion, and partnership of those who contributed to this mahi are shaping a smarter, safer, and more sustainable water future for all.

Executive Summary The Water Research Roadmap, commissioned by Water New Zealand and developed with research support from Cogo, establishes a collective framework for research investment and collaboration to build a resilient, sustainable, and world-class water sector. It responds to the sector’s most pressing challenges, climate adaptation, infrastructure renewal, and public confidence, by defining a shared agenda for evidence-based action.

Aotearoa New Zealand’s water sector stands at a pivotal moment. With water infrastructure investment projected to reach over $5 billion annually, the need for research that enhances efficiency, capability, and long-term value has never been greater. Yet current research remains fragmented, underfunded, and insufficiently aligned with national science reform. This roadmap draws on insights from more than 200 sector experts, ensuring that the priorities identified reflect real-world challenges, local expertise, and national aspirations.

Strategic Focus The roadmap defines twelve priority research areas grouped under three integrated themes that align with the Towards 2050 Transformation Vision: 1.Water Resilience and Infrastructure – Generating evidence-based guidance for planning, investment, and adaptation to deliver climate-ready, resilient water systems.

2.Governance and Social Impact – Developing governance models, partnerships, and workforce capability that strengthen sector leadership, equity, and public trust.

3.Water Intelligence and Technology – Advancing innovation in data, modelling, and treatment to improve decision-making, safeguard health, and enable open, reliable, and interoperable systems.

Together, these priorities highlight where new knowledge, investment, and partnership will deliver the greatest benefit for people, the environment, and the economy. Strong foundations already exist in climate adaptation, cultural partnership, and digital readiness, but several challenges persist: Research activity across the sector is underway, yet fragmented and difficult to access.

Limited coordination and short-term funding restrict long-term progress.

The workforce lacks the capacity to meet future regulatory, technical, and infrastructure demands.

4 Water Research Roadmap - October 2025 - Water New Zealand

Recommended Actions To address these challenges and realise the sector’s research vision, this roadmap recommends the following actions: Align national and sector research priorities to strengthen coordination, reduce duplication, and deliver shared outcomes.

Establish sustainable funding pathways to support long-term, mission-led research and innovation that address critical sector challenges.

Deepen collaboration across the sector by connecting councils, iwi, academia, and industry through coordinated research hubs and shared initiatives.

Increase research impact and inclusivity by embedding mātauranga Māori, promoting open-access data, and applying consistent impact reporting across projects.

Alignment with National Science Reform This roadmap complements the Government’s reform of the science, innovation, and technology system, particularly its emphasis on mission-led, impact-driven research that delivers measurable economic and environmental outcomes. Water research aligns strongly with these national priorities, offering opportunities to drive productivity growth, reduce infrastructure costs, and deliver high public returns on investment. International evidence shows that every dollar invested in water research can generate five to tenfold economic and social benefits.

Looking Ahead The Water Research Roadmap provides a clear pathway for collective action; uniting research, policy, and practice to deliver measurable progress toward a sustainable and equitable water future. By aligning investment, capability, and innovation, it supports the realisation of the Towards 2050 vision: a resilient, connected, and culturally grounded water sector that delivers enduring benefits for all New Zealanders.

5 Water Research Roadmap - October 2025 - Water New Zealand

Introduction The Towards 2050 Transformation Vision provides a unifying blueprint for how Aotearoa New Zealand’s water sector can evolve over the next generation — from fragmented systems and short-term responses toward a future defined by shared stewardship, equity, and innovation. Developed through extensive consultation with members, iwi, government, and communities, the transformation framework outlines the collective outcomes the sector seeks to achieve by 2050: sustainable services, empowered capability, enduring partnerships, and the restoration of trust in water management.

The Water Research Roadmap builds directly on this foundation. It translates the aspirations of Transformation 2050 into a focused programme of research and innovation, identifying where investment and collaboration will make the greatest difference. By aligning research priorities with the long-term transformation goals, this roadmap ensures that the sector’s knowledge base evolves in step with its institutional and cultural reforms — creating a continuous feedback loop between evidence, practice, and policy.

The roadmap also responds to the rapid changes now shaping the water landscape — climate adaptation, digital transformation, new regulatory settings, and the integration of mātauranga Māori and science. Rather than restating the challenges, it provides a structure for action: identifying the research needed to build resilience, strengthen governance, and accelerate the technologies and workforce capability that will define the sector’s future.

The twelve research priority areas identified in this document are therefore not standalone initiatives but coordinated pathways toward the 2050 outcomes.

These are organised into three centres of focus (integrated themes) — Water Resilience and Future Infrastructure, Water Governance and Social Impact, and Water Intelligence and Emerging Technologies — each capturing the key areas where targeted research can drive systemic transformation.

Integrated Themes and Research Priority Area Integrated Theme 1: Water Resilience and Future Infrastructure Focuses on planning, risk management, infrastructure, and adaptation. Priorities include national resilience standards, communication of risk, condition assessment technologies, and adaptation strategies for climate change.

Integrated Theme 2: Water Governance and Social Impact Explores iwi partnerships, governance models, workforce capability, and public perception. Priorities include mātauranga-driven water management, workforce pathways, and insights into community engagement and behavioural change.

Integrated Theme 3: Water Intelligence and Emerging Technologies Addresses innovation in treatment, data, and modelling. Priorities include managing contaminants, developing AI and predictive tools, improving data accessibility, and advancing research on emerging pollutants and technologies.

Developing the Roadmap The project, funded by Water New Zealand and the Water Services Managers Group, aimed to guide funders and leaders in targeting research investment.

Approach: Mapping of the water sector and existing research.

Thirty personal interviews with key sector stakeholders.

Thematic analysis to identify common research areas.

Validation through feedback loops and a survey with 164 respondents.

Data used to refine and finalise research priorities.

In early 2025, Cogo were engaged by Water New Zealand to support the development of a Research Roadmap that identifies and sets out priority areas of research for the water sector to action. The main purpose of the Research Roadmap Project is to enable funders and researchers to better understand where to target efforts to support the sector’s ongoing development in line with the Transformation 2050 strategic goals. Water sector and other infrastructure leaders, researchers and government - both domestically and internationally - are key audiences for the project outputs.

A rigorous stakeholder consultation process has brought together and distilled insights from over 200 representatives of the water sector gathered during indepth one-to-one interviews and an online survey to support the creation of the Research Roadmap. Full methodological details are provided in Appendix 1: Methodology.

This approach has ensured that the Research Roadmap presents a way forward that is based on current expert advice and industry needs and has the broad support and agreement of the sector, which is now primed for collaboration and action.

The Current State of Play:

Key Challenges and Research Landscape

Water Sector Structure: The governance and management of water in Aotearoa New Zealand involves a wide network of organisations spanning central and local government, regulators, service providers, iwi and Māori entities, and research and advocacy groups (for detail see Appendix 2). Each plays a distinct role in shaping how water is managed, delivered, and safeguarded—from setting national policy and regulating quality, to providing infrastructure services, advancing research, and ensuring that te ao Māori and co-governance principles are embedded in decision-making.

Every change in government resets the clock – it’s hard to build momentum when the rules keep shifting.

We don’t know what the final shape of regulation will look like, which makes long-term planning nearly impossible.

Participant quotes

Current research During the mapping exercise carried out at the outset of the Research Roadmap project, it became clear that much of the research undertaken across Aotearoa New Zealand’s water sector is not easily accessible.

The degree of difficulty encountered during the desktop search in accessing publicly-available research documents is reflected in a final compiled list of just 53 documents (see Appendix 3 for summary). Note this is supplemented by the repository of conference papers and technical reports that can be accessed at www.waternz.org.nz/resourcehub This experience aligns with interview and survey data collected as part of this project that also points to opportunities for greater sharing of information and stronger collaboration across the various entities in New Zealand that are engaged in water research. While many do share research outputs there does not appear to be a systematic way to ensure that this happens consistently.

Many in the sector are largely unaware of what research is being carried out elsewhere in the water sector at any given time leading to one of this report’s key recommendations to establish a sector-wide research platform or hub.

9 Water Research Roadmap - October 2025 - Water New Zealand

While the main purpose of the online survey was to explore future research priorities, the consultation also provided an opportunity to invite sector stakeholders to share details of current or recent research they are/were involved in or that they believed to be significant for the sector. Many stakeholders wrote in current (89 respondents) or recent (53 respondents) research topics with varying levels of detail. Given that these entries were selfreported in an anonymous survey, it wasn’t possible to capture information on who the researchers are or what entity they are from, nor sufficient detail to be able to follow up on the research projects mentioned.

Producing a comprehensive catalogue of all research activity in the water sector was beyond the scope of this project, nonetheless the material gathered provides an indication of where water research activity is currently concentrated. The data gathered in the online survey is presented as research areas, ordered by the frequency that they appear as themes in the survey data (see Tables 1 and 2). Further detail and all citations can be found in the accompanying research report on the Water New Zealand website.

10 Water Research Roadmap - October 2025 - Water New Zealand

Current research During personal interviews carried out as part of the Research Roadmap Project, water sector stakeholders were asked for their perspectives on the most significant challenges or concerns facing the sector as a whole. Collated and analysed data collected across 30 interviews identifies common themes that describe both short-term and long-term challenges according to those in the sector:

Short-Term Challenges: Funding pressures and resource constraints.

Workforce shortages.

Policy and regulatory uncertainty.

Public trust and expectations.

We’re constantly under pressure to deliver with shrinking budgets and rising expectations.

Smaller councils in particular simply don’t have the resources to manage compliance and service delivery.

Participant quotes

Long-Term Challenges: Embedding Māori partnership and inclusion.

Ageing infrastructure and asset renewal.

Climate change resilience.

Lack of sector coordination.

Research and best-practice gaps.

We don’t even have a complete map of where all the assets are, let alone the condition they’re in.

Decades of under-investment mean we are inheriting a ticking time bomb.

Participant quotes

11 Water Research Roadmap - October 2025 - Water New Zealand

Research Landscape: Much research is difficult to access or poorly coordinated.

Findings support the creation of a shared national research platform

We don’t have agreed standards or clear best practice for many critical areas.

Research is piecemeal – there’s no overarching strategy linking it all together.

Participant quotes

What the Sector Wants: 12 Research Priority Areas

Based on insights gathered from over 200 water sector stakeholders in response to the broad question – “What research do you believe the water sector must prioritise?”, 12 research areas have been identified as priorities for the sector.

Together, these priorities express a shared ambition for a smarter, more connected water sector—one that values research not only as a source of technical solutions but as a foundation for sharing, resilience, and sustainable transformation.

For the purposes of this report, the twelve priority research areas are grouped under three integrated themes:

Water Resilience

1

Water Governance

3 2

Water Intelligence

12

Integrated Theme 1: Water Resilience Priority research areas: 1.1 Risk and Resilience 1.2. Climate Change and Environmental Impacts 1.3. Infrastructure and Asset Management 1.4. Workforce and Capability

Integrated Theme 2: Water Governance Priority research areas: 2.1 Iwi Partnerships and Co-Governance 2.2 Public Perception and Communication 2.3 Public Behaviour and Risk Response 2.4 Governance and Decision-Making

Integrated Theme 3: Water Intelligence Priority research areas: 3.1 Water Quality and Public Health 3.2 Contaminants and Treatment Innovations 3.3 Planning and Performance 3.4 Data, Modelling and Economic Tools A number of research programmes, opportunities for cross-sector innovation, and policy reform or development sit within each of the integrated themes and associated 12 priority research areas. These were identified through a process of analysing and coding, using thematic analysis, the many suggestions of specific research topics made by sector stakeholders. To further help shape decision making these have been assigned a tiered classification level (high, medium or low priority), based on the frequency with which the research theme appeared in the interview and survey data (shown in detail in Tables 4, 5 and 6 below).

The following visuals summarise what the sector identified as most critical. For each integrated theme the priority research areas and opportunities for future collaboration and investment are detailed (tables 4, 5 and 6). Together, these insights provide a robust evidence base to guide coordinated research and funding decisions across Aotearoa New Zealand’s water sector.

While we sought feedback on priority areas, it is worth noting that although the analysis presents a unified picture, there are multiple, differing priorities across different areas. In reality, all the research priority areas identified as part of this work have been identified as important by the water sector stakeholders participating in this consultation and it is important to ensure that future investment decisions are not constrained by the priority levels that have been assigned, but also take into account current strategic priorities and obligations as well as the funding opportunities that may be available for specific projects.

The twelve research areas build directly on the Towards 2050 Transformation Vision, which identifies seven levers for system-wide change: Te Mana o te Wai; Capability and Education; Environment and Climate; People and Community; Digitally Enabled; Planning and Standards; and Smart Buyer. The research priorities translate these transformation levers into actionable focus areas— balancing practical needs such as asset resilience, data quality, and workforce capability with longer-term goals for innovation, collaboration, and knowledgesharing (see Table 3 below). The table also consolidates the highest-priority research needs across each focus area and expresses them as research questions. While not intended to be comprehensive, it identifies areas where research could generate rapid and meaningful impact.

Progress and Ongoing Initiatives Water New Zealand and its partners already have work underway which supports the priorities identified via the research roadmap consultation phase.

In summary these include:

Conferences From the flagship Water New Zealand Conference & Expo and Stormwater Conference & Expo, to specialist events on topics such as backflow, modelling, and climate adaptation, Water New Zealand conferences are a cornerstone of research exchange across the sector. They bring together researchers, practitioners, iwi partners, and policy-makers to share new insights, test ideas, and build collaborative networks. Many sector innovations and policy shifts have emerged from conference discussions, with peer-reviewed papers and presentations made freely available online to extend their impact.

Technical Reports

Water New Zealand’s technical reports provide the sector with trusted, evidence-based insights on emerging issues, standards, and best practice.

Developed in collaboration with members, industry partners, and subject matter experts, these reports translate research into practical guidance for operators, planners, and decision-makers. Topics range from climate adaptation to asset management and digital transformation.

Special Interest Groups (SIGs) The Water New Zealand Special Interest Groups (SIGs) form the backbone of sector collaboration and applied innovation. Each group brings together practitioners, researchers, and regulators to share experience, identify sector needs, and develop standards and tools for their discipline. SIGs play a vital role in bringing best practice into the sector, shaping policy submissions, and mentoring new professionals. Through their leadership, the sector maintains momentum on critical topics such as stormwater management, backflow prevention, climate resilience, and digital water systems.

Webinars and Podcasts

Water New Zealand’s webinars and podcasts provide accessible platforms for sharing knowledge, showcasing research, and highlighting innovation across the water sector. Delivered throughout the year, they enable members to stay up to date with new findings, technologies, and policy developments, regardless of location. Presenters include leading researchers, practitioners, and iwi partners, ensuring a diversity of voices and perspectives. The interactive webinar format supports discussion and knowledge exchange, helping to foster a connected and informed professional community.

Recordings and resources remain available online, creating an ongoing library of sector learning.

Other Initiatives Water New Zealand supports a broad range of initiatives that strengthen the sector’s capability and alignment with the Towards 2050 vision. Through programmes advancing Treaty partnership, published articles, new workforce pathways, and tools for climate adaptation and digital readiness, the organisation helps embed cultural values, innovation, and evidence-based practice. Collaborative work on standards, procurement, and community engagement further ensures that the sector continues to evolve in a cohesive, future-focused way; building resilience, trust, and shared purpose across Aotearoa New Zealand’s water network.

Key Gaps The consultation process reveals that currently sector initiatives have strong engagement and progress across multiple research and knowledge-sharing platforms. However, activity remains largely fragmented, with conferences, reports, formal research, and partnerships operating in isolation rather than through a shared coordination framework. Because the work is spread out, it’s hard to see overall progress, spot overlap or opportunities to work together, plan funding in advance, and build the momentum needed for real change.

Additionally, limited sector guidance on priority research outcomes means public sector researchers (those in universities, PROs and other publicly funded research organisations) may not fully understand how their work contributes to critical infrastructure planning and investment. Establishing clearer mechanisms for coordination, data sharing, and outcome tracking—such as a centralised research hub or common impact framework—would enable more coherent and transparent progress across all research themes.

Gaps also exist in long-term alignment, and funding. While dissemination occurs, research outputs are not always valued, easy to locate, reusable, or connected to decision-making. Embedding mātauranga Māori varies across programmes, and capability-building efforts are not yet systematically linked to research priorities or national reform objectives. Finally, without a long-term funding and partnership framework, current activity is largely supported through short-term, project-based investment, which is typically modest — often in the order of $20,000 to $80,000 total for industry-applied research.

21

Action Framework The priorities identified through this work provide a shared framework for coordinated investment, research, and action across Aotearoa New Zealand’s water sector. This roadmap serves both as a strategic guide and a practical implementation plan, focusing collective effort, mobilising partnerships, and driving measurable progress toward shared outcomes.

Strategic investment in research is essential not only for public health and environmental resilience but also for productivity and efficiency, ensuring that every dollar spent on infrastructure delivers lasting value. The twelve research priorities outlined earlier form the evidence base for this action framework, directing future activity toward the sector’s most critical knowledge gaps.

Funders can use the 12 priority research areas to target investment where it will have the greatest impact, build enduring partnerships, and strengthen longterm capability.

Researchers can align their work with the integrated themes or research questions to ensure relevance, deepen collaboration with iwi and practitioners, and translate new knowledge into practical solutions for the sector.

National Context Aotearoa New Zealand’s science system is being reshaped to improve coordination, capability, and impact across research, innovation, and education.

The Science System Advisory Group (SSAG) and MBIE’s Science and Innovation Strategy emphasise the need for a more streamlined and connected research system that aligns science, policy, and mātauranga Māori to maximise public value.

Key reforms include establishing a National Research Council (NRC) to oversee funding, Public Research Organisation New Zealand (PRONZ) to unify Crown Research Institutes, and the Prime Minister’s Science, Technology and Innovation Advisory Council (PMSTIAC) to guide national research priorities.

Additionally, in support of this shift, new entities, including Innovation New Zealand and Trade and Enterprise New Zealand, are being developed. As these reforms are in the early stages of design, the full scope of activities is not yet known.

Overall, it is intended that these changes will streamline decision-making, promote collaboration, and embed Māori knowledge as a cornerstone of the national research architecture.

22 Water Research Roadmap - October 2025 - Water New Zealand

Why This Matters for the Water Research Roadmap Water research sits at the centre of Aotearoa New Zealand’s mission-led, applied science system—supporting national goals for climate adaptation, infrastructure resilience, and sustainable resource use. The Water Research Roadmap highlights how water research can contribute to these national missions by identifying the pathways that deliver the greatest environmental, economic, and social benefit.

It emphasises the need to build capability across councils, iwi, universities, and public research organisations, while strengthening shared data infrastructure and promoting partnership-based, trust-centred approaches to research. In doing so, it aligns with the Science System Advisory Group’s vision for a more collaborative, inclusive, and impact-driven science ecosystem.

From Strategy to Action The collective efforts of Water New Zealand, WSMG, SIGs, and the wider research community have laid the foundation for long-term transformation.

The phased roadmap provides a clear pathway for coordinating sector progress and aligning with national science reform.

Over the coming decades, the sector needs to: Align and integrate — connect sector research priorities with emerging national structures such as the NRC and PRONZ. Secure sustainable funding — embed water research within national investment frameworks to enable long-term collaboration.

Strategic Actions for Water New Zealand Through its ongoing role convening the sector and disseminating research through conferences, technical reports, and Special Interest Groups, Water New Zealand is well positioned to lead the next phase of the Water Research Roadmap. Building on this foundation, Water New Zealand will focus on four strategic action areas: Unlock Funding: Champion new research investment models, promote cofunding, and develop partnerships with national funders.

Foster Collaboration: Create an open-access research hub, convene sector forums, and strengthen conference and thematic networks.

Identify and Update Priorities: Regularly review research themes, benchmark internationally, and support collaborative research hubs.

Advance Capability and Impact: Evaluate research outcomes, coordinate sector data standards, embed mātauranga Māori, and expand sector training pathways.

Role of Special Interest Groups (SIGs) Special Interest Groups are the engines of knowledge exchange within Water New Zealand. They provide essential links between best practice, operations, and policy. To maximise their contribution, Water New Zealand will work with SIGs to explore: Expanding cross-SIG and multidisciplinary research projects to accelerate the translation of findings into practice.

Strengthening engagement with iwi, councils, PROs, universities, and international networks to support Treaty-aligned, place-based co-design.

Developing and publishing standards that improve consistency in monitoring, benchmarking, and reporting.

Supporting dissemination and impact monitoring through research liaison roles, accessible summaries, and structured feedback loops.

25 Water Research Roadmap - October 2025 - Water New Zealand

Actions for the Wider Research System While Water New Zealand cannot direct the actions of others, this roadmap highlights practical opportunities for researchers, funders, and government agencies to align their work with sector priorities. New Zealand’s persistent underinvestment in science—described by the Science System Advisory Group as a “parsimonious attitude to research funding” and a key reason for low productivity growth—presents both a challenge and an opportunity.

With new water infrastructure investment projected at $47.9b over the next 10 years, even modest increases in research investment could deliver transformative value: international evidence shows returns of five- to ten-fold on public research, with similar studies in Australia demonstrating up to $13 in benefits for every dollar invested.

Strategic research can reduce long-term infrastructure costs, strengthen innovation pathways, and unlock the productivity gains that have long eluded New Zealand’s economy. Achieving this, however, requires support from the Government and funders to enable co-investment, build research capability, and create innovation mechanisms that the sector, currently constrained by historic underinvestment, cannot deliver alone.

Realising this opportunity will require shared commitment across the system.

The following actions outline how researchers, funders, and government can use this roadmap to guide their investments, partnerships, and policies toward a more productive, resilient, and innovative water future.

Researcher/Research Organisation Actions Researchers are central to transforming the roadmap’s priorities into actionable, high-impact science. By aligning projects with sector needs and national missions, researchers can help ensure that water research directly informs policy, practice, and innovation. To maximise relevance and impact, researchers can: Align research focus with the roadmap’s priority themes and the evolving national science and innovation missions.

Co-design projects with iwi, councils, industry, and community partners to ensure outcomes are practical, equitable, and regionally grounded.

Embed mātauranga Māori and support Māori partnership and leadership across all stages of research design, delivery, and translation.

Contribute to open science by sharing data, publishing through accessible platforms, and building collective capability across the sector.
