The provision and management of river schemes is the responsibility of Regional Councils through the Local Government Act. The origins of the schemes date back to the Soil and Conservation Rivers Control Act 1941 which recognised that flooding and drainage problems were best considered on a catchment basis.
Traditionally the river scheme flood protection approach relied on structures based on European technology and science to control floodwaters and improve drainage.
The historical approach of hazard control and “holding the line” is no longer considered sustainable against a backdrop of change. Our New Zealand climate is changing, and these changes will continue for the foreseeable future. Adaptation is essential to ensure our river schemes remain sustainable in the long term.
Long Term Sustainability
The strategic view for local authority river management is now more focused on reducing the long-term risk of flood hazards, encouraging a more natural and less engineered/confined river system to improve overall river and ecological health, promoting environmentally and economically sustainable land-use practices along with raising awareness in our communities. An integrated approach to flood risk management is needed to ensure river schemes remain viable and affordable.
Our councils are concerned with the long term environmental and financial sustainability of existing river schemes and are investigating alternative flood management options while considering international and national evolving best practise.
Bay of Plenty Regional Council - River Scheme Sustainability Projects
The need for the River Scheme Sustainability project was identified in 2011 following a number of flood events. As part of the project defined work streams were developed including the optioneering work stream. This work stream looked at long term sustainable flood management practices for the Bay of Plenty Regional Councils five major river and drainage schemes. Exploration included investigating catchment wide options, general and catchment specific ideas, enhancing existing structures, structural and non-structural solutions.
This webinar will present a floodplain assessment methodology and solutions that can be considered for any catchments.
Presenter: Katalin Maltai
Katalin Maltai Senior Projects Engineer working for the Bay of Plenty Regional Council has been leading the River Scheme Sustainability Project for over 10 years and delivering long-term flood mitigation solutions for the region, while also involved in climate change adaptation, sea-level rise, coastal hazards, risk management, hydrological and hydraulic assessments.

This webinar provides an overview of the assumptions, methods, limitations and regional scale finding results associated with the Deep South’s Climate Change impacts project. This project coupled the IPCC 5th climate projection ensemble for New Zealand (Ministry for environment 2018) with an a-priori parametrised hydrological model across New Zealand.
As part of the seminar, I will use case studies to illustrate some of the challenges associated with the use and interpretation of those datasets to inform water resource and hydrological extreme investigations. The learnings form this project are used to inform method development associated with the use of the IPCC6th climate projections for New Zealand to be released in June 2024.

A case study: how to manage the powerful and dynamic Waiho River in South Westland.
This webinar focuses on the work completed by the 2023 Waiho Technical Advisory Group (TAG), which was formed by the West Coast Regional Council in response to the ongoing aggradation of the riverbed, and the development of an avulsion path between the Waiho River and the Tatare Stream in February this year. The TAG was tasked with producing a 10-year management plan for the river. Utilising the extensive geomorphic understanding of the river system, a risk assessment of each stopbank in the protection network, and the PARA framework, the TAG developed a five phase plan involving a managed retreat from the Waiho’s true left floodplain. This rather drastic action will allow the Waiho River to access it’s entire fan surface (as oppose to just one third), giving it more space to distribute its incredibly high sediment load across, which slow the rate of vertical aggradation, and therefore reduce the pressure on the developing avulsion, as well as the true right stopbanks which protect the Franz Josef township.
Presenter: Matthew Gardner, BE (hons) Natural Resources, CMEngNZ and CPEng, Land River Sea Consulting Ltd
Matthew Gardner is the director and principal engineer at Land River Sea Consulting, a small Christchurch-based specialist engineering consultancy. First exposed to the Waiho River on family hiking trips as a child in the 1980’s; he was then educated in the classroom and on field trips to Franz Josef by Professor Tim Davies whilst studying Natural Resources Engineering at the University of Canterbury in 2004/2005. His first professional involvement with the river began in 2014 when he was tasked with building a hydraulic flood model of the river for the West Coast Regional Council. Since then, he has been involved in a range of investigations and workshops on the river helping the West Coast Regional Council as well as the Department of Conservation better understand the big picture behaviour and hazard profile of the river. He has conducted several hydraulic modelling studies on the river as well as detailed analyses in relation to changing bed levels and behaviour of the river over time.

The adaptation agenda is not new, but appears it is only able to be progressed once people have experienced severe impacts and the scale and scope of damages have become clear. So what have we learned from our experience?
To prepare for the impacts of climate change in a climate exposed and unstable pluvial country we need fit for purpose governance and institutional arrangements that enable implementation of adaptation actions, planning frameworks and decision tools that account for dynamic changing risks, in tune with our Treaty partners, and iwi/hapu cultural values and that are inclusive of wider community values.
This webinar addresses these issues, illustrated with practical examples from New Zealand.

Stationarity is now invalid for dealing with the continually changing risks we face from climate change and the inherent widening uncertainties over time.
Consequently, a different approach to risk assessments and risk treatment must explicitly include the:
- increasing rate of change in risk over time
- interlinkages and feedback within the catchment system including cascading impacts
- compounding of coastal and freshwater hazards in coastal lowlands (including groundwater and salinisation)
- deepening uncertainties stemming from multiple possible coastal-climate futures
Being explicit about planning and/or design timeframes is now a critical component of risk analysis, when considering adaptation, whether using nominal or policy-driven timeframes (thereby artificially closing off ongoing changes in risk) or taking a realistic view of the permanence of the built environment and land-use decisions. Even short-term or incremental adaptation can lead to path dependency to a particular course of action or maladaptation and increasing residual risk down the track as climate-related risks unfold.
Rather than a conventional “predict-then-act” approach, we need to shift to an adaptive pathways paradigm taking a systems viewpoint (ISO 14090: 2019). Starting with a set of scenarios and re-framing risk assessments (ISO 14091: 2021), dynamic adaptive approaches provide a flexible solution and engagement space to explore and devise alternative pathways for fluvial and coastal plains that perform across a range of possible futures, considering the implications and limits of incremental versus transformative (eg, making room for the river, managed retreat, enhanced lowland wetlands) adaptation options.

This session introduces floodplain sediment archives and their potential for flood series extension in New Zealand. A broad, nationwide overview of centennial-scale river activity in the last 10,000 years will be followed by focusing on specific flood histories in discrete catchments. Assessing flood risk is presently constrained by short (generally ~50 year) gauged river flow records that poorly represent the distribution of hydrological extremes because these records typically do not include the largest floods generated in a catchment. There is a need to extend flood series to improve our understanding of flood hazard and risk, particularly in light of a rapidly changing climate. Floodplain sedimentary archives offer the prospect of generating flood histories over centuries and even millennia because they directly record the sediment signature of discrete flood events. These palaeo flood reconstructions provide a window into historic and prehistoric floods occurring within a catchment during a range of climate conditions, which allow us to better prepare for future floods.

Climate change will continue to super-charge the atmosphere with water vapour and energy, ensuring stronger storms and heavier rainfall as things continue to warm. But, when it isn’t raining, the weather looks drier, with faster evaporation and greater chance of drought. One signal that comes through clearly in future projections of river flows is an increase in variability. Even if the overall flows are not expected to change, variability in the flows is likely to increase. I’ll discuss the overall picture of how the climate is changing, and I’ll relate it to New Zealand river flows, water availability and extreme events.
Presenter: James Renwick, Climate Researcher

Lynette discusses her research team's study on encouraging key beneficial behaviours (reporting stormwater pollution, installing urban rainwater tanks, volunteering) for urban freshwater biodiversity.
Residents’ behaviour is fundamental to protecting and restoring freshwater biodiversity in urban areas. However, a key challenge facing government agencies, environmental organisations, and community groups is convincing people to engage in activities that will benefit urban freshwater biodiversity. Lynette will describe a systematic approach to designing effective human behaviour change interventions, illustrated with a practical example for improving volunteer involvement with urban freshwater restoration projects.
The research team conducted a set of nationwide online surveys and established volunteering for urban freshwater restoration as a key target behaviour. They developed a randomised control trial with a restoration group in Kirikiriroa | Hamilton and tested ways to increase first-time volunteer participation and investigated volunteering benefits. Participants were recruited through social media and 627 potential first-time volunteers were identified. In the first stage of their experiment, they found that a $50 voucher combined with a nudge was most effective at increasing volunteer rates at an actual event. In the second stage, they found that volunteering for the first time increases future volunteering behaviour, generates positive spillovers to other pro-environmental behaviours and strengthens environmental attitudes and self-identity.
This research was partly undertaken in collaboration with Robbie Maris (University College London), Zack Dorner (Lincoln University) and Fredrik Carlsson (University of Gotherburg).

Aotearoa New Zealand’s BioHeritage Challenge, Ngā Koiora Tuku Iho ‘Empowering Environmental Stewardship and Kaitiakitanga’ team presents: Te-ia-o-te-Rangi: Exploring localised Tūhoe astronomical knowledge in relation to the localised environmental management of water.
Presenter: Nathan Matamua
Nathan will be presenting qualitative research that aims to shed light on how a local Māori community can be better empowered to enact kaitiakitanga. Sharing kōrero with two Tūhoe tohunga (experts) from the local Tūhoe community of Ruatāhuna, the research draws on their experiences and meaning making when considering their understandings of the relationship between localised Tūhoe star lore and localised environmental knowledge associated with water.
Through analysis of collected data, the research provides a discussion on a lived Tūhoe perspective in relation to understanding water quality, and how these understandings may better empower local communities to enact local forms of kaitiakitanga.
Nathan Matamua (Ngāi Tuhoe) is a member of the BioHeritage Challenge/Ngā Koiora Tuku Iho ‘Empowering environmental stewardship and Kaitiakitanga' team. Nathan was born and raised in Levin, a town to the south of Palmerston North. “My tribal home is in the Bay of Plenty,” says Nathan. “I’m Tūhoe, and I’ve always been made aware of that. But even though we’ve constantly travelled home, in many ways, I still see myself as an outsider.”
Nathan has recently completed a Master’s in Psychology at Massey University and has found this a way of reconnecting with his roots and with his whānau. “Prior to being a student, I was a supply chain manager for a global company,” says Nathan. “I had the good career, but I wanted to spend a bit more time focused on family.” Studying was a way of doing that, and Nathan has found that it has naturally progressed to reconnecting with his identity.

This webinar offers the opportunity for river engineers and environmental managers to learn about Te Tiriti o Waitangi/the Treaty of Waitangi (the Treaty) and its relevance to contemporary river governance and management policies, planning, and strategies in Aotearoa New Zealand. The webinar begins by providing a brief overview of the history of the Treaty, which includes the reasons for disagreements about what the Treaty means.
Next, it will explore what Treaty principles are and what it means in terms of river governance and management approaches and on-the-ground practices. The different ways in which the Treaty (duties and principles) is recognised in relevant legislation, court decisions, and proposed bills are discussed, with a focus on providing environmental managers and water engineers with an understanding of the legal dimensions of the Treaty as well as how it is embedded within Te Ao Māori (the Māori world) and Māori concepts and values.
The webinar is designed to be an introduction to the Treaty and provide case studies that demonstrate why the Treaty is of critical importance to improving how rivers are governed and managed in Aotearoa New Zealand.
Presenter: Dr Meg Parsons, School of Environment, The University of Auckland
From my early days as a student, I have always been interested in the relationships between people and places, and how these relationships shift, change, are maintained and contested over time. My research is transdisciplinary in scope and nature, and crosses the boundaries between human geography, historical studies, and Indigenous studies. This transdisciplinary and intersectionality emerged from my own experiences as someone of mixed heritage (Māori/Pākehā/Lebanese) who grew up in small-town Aotearoa New Zealand, and noticed the ways in which different individuals and communities relationships with each other and their local environments were tied to their identities, values, histories, and different knowledge systems; all of which was bound up in their memories of and experiences of colonialism, social-environmental crises, and perceptions of what constituted healthy people and environments. My research is focused on examining how different values and belief systems are translated into environmental policies and actions, the ways in which specific historical narratives, memories, and discourses influence both the construction and practices of scientific knowledge, and how colonialism influences contemporary Indigenous societies' responses to climate change and other environmental changes.
Key areas of research include:
- Historical geographies of colonialism and environmental change
- Indigenous peoples' perceptions and responses to climate change
- Decolonising approaches to freshwater and coastal governance and management regimes
- Socio-cultural dimensions of climate mitigation
- Climate change adaptation and justice (social, climate, gender)
- Decolonising methodologies and co-production of knowledge
- Interaction of different knowledge systems (western scientific, Indigenous and local knowledges)
- Indigenous histories and conceptualisations of health and wellbeing

Join us for this one-hour webinar to learn about evolving freshwater policy and how it is changing freshwater management in Aotearoa New Zealand. The National Policy Statement for Freshwater Management (NPS-FM) is central to river management planning, consultation engagement and operational activities. Te mana o te wai was introduced as a key concept in the NPS-FM 2014 and in the most recent NPS-FM 2020 was elevated to a principle that puts the health and well-being of freshwater bodies at the forefront of decision-making about water. In line with the NPS-FM, this session will broaden the view beyond water quality and habitat management to include other aspects of river ecosystem health such as aquatic biota and ecosystem processes. A broadening of our view of rivers beyond ‘channels’, and ‘drains’ is more closely aligned with a Māori worldview of waterways. Additionally, this seminar also introduces Māori concepts and values relevant to understanding and implementing the NPS-FM such as water as taonga (treasure), mauri (life force of water), and mahinga kai (food-gathering).

In this webinar as part of our cultural series you will learn more about the how to of navigating towards te mana o te wai. Linda will share with you methods to assist with empowering and enabling iwi hapu involvement.
This will consider determining the right level of engagement, including considering the purpose and goals of the engagement, as well as the level of importance to a Council and level of interest for Māori.
Planning engagements need to consider what suits the parties including capacity and capability, possible financial support and remuneration investment considerations, timeframes, along with discussions of wider issues, understanding kawa (protocol/rules) and tikanga (customs).
Genuine and effective engagement is critical as part of supporting ongoing relationships and for leading to improved outcomes for the benefit of our work and community wellbeing.

In this webinar we’ll follow a river from the mountains to the sea: What do you find in a small stream close to a spring? What changes when the river grows with tributaries joining? What’s special about the wide, braided river before it meets the sea? Meet the in-stream community: plants, invertebrates and fish, and why they can tell us about what’s happening in their environment. And finally: how do our activities on land change the aquatic environment?

New Zealand’s rivers provide crucial breeding habitat for a number of threatened bird species, many of which are found nowhere else on earth. In this webinar we will introduce you to some of the unique bird species that call our rivers home and discuss both the positive and negative impacts that river management activities can have on these species. We will present examples of initiatives being undertaken around the country to maintain or improve river bird habitats in the context of flood mitigation or gravel extraction activities, and will discuss additional work that could be carried out in the future to further improve on these efforts.
Presenter: Nikki McArthur, Independent Ecologist
Nikki McArthur is an independent ecologist specialising in the conservation management of New Zealand birds and their habitats. Nikki has spent over a decade monitoring shorebird populations throughout the country, and has spent a number of years working with regional councils and the gravel extraction industry to improve the management of shorebirds breeding on rivers in the Hawke’s Bay, Wellington and Canterbury regions.

How can you tell if a stream is healthy? Often, the first question that comes to mind is: Is the water clean? But chemical water quality is only one part in complex aquatic ecosystems where everything is interdependent: Plants and animals, habitat, chemical, physical and biological processes and connectivity to land and groundwater are all important components of stream ecosystems and determine if they are healthy and support a resilient and healthy community of plants and animals. How is ecological health measured and what are our obligations under the NPSFM?
Presenter: Michael Pingram, Waikato Regional Council
Michael is a freshwater ecologist enthusiastic about stream health and large river restoration. Since 2014, Michael has been working for the Waikato Regional Council as freshwater scientist, analysing and reporting on freshwater ecology, carrying out investigations, and providing science advice to inform policy development. In particular, overseeing the region-wide ecological monitoring of streams, with an emphasis on the aquatic macroinvertebrate and habitat components. In collaboration with other research organisations, he has broad research interests including the development of ecosystem health indicators for large non-wadeable waterways, and ecological responses of invertebrates and fish in multi-stressor environments. He is now Team Leader the Water Quality and Ecology Science team, a passionate team of scientists tasked with covering the Councils’ science needs related to the water quality and ecosystem health of rivers and lakes.

Over the past 100 years New Zealand’s lowland waterbodies have been modified by streambed lowering, channel straightening and field drainage. Drainage has now occurred to the extent that over 90% of NZ’s wetlands have been lost. While wetland drainage has now largely ceased, lowland waterbodies are subjected to ongoing channel maintenance through mechanical macrophyte clearing, weed spraying and streambank reconstruction. These actions are undertaken to ensure the productivity of surrounding farmland and to protect homes and infrastructure from high water levels. Progressively, many lowland wetland-stream complexes have been replaced by grid-patterned drain networks. Yet, these modified waterbodies are still freshwater habitats that can harbour surprising high, and often overlooked, instream values.
In this webinar, I will explore how drain maintenance practices alter stream habitat and affect in-stream life—with a focus on freshwater fish. I will discuss a 10-year fish and habitat monitoring programme in Waituna Creek (Southland), which captured a major stream bank reconstruction initiative and a restoration project that included installing two-stage channels and instream habitat structures. I will also discuss an ambitious project in the Ararira-LII River (Canterbury plains), that aims to reimagine catchment drainage by consolidating and scaling-up various alternative ecosystem friendly drainage management methods to an entire lowland catchment.
Presenter: Robin Homes, freshwater ecologist, Cawthron Institute

Communities and regional authorities around New Zealand actively manage river corridors to protect lives and property from flooding and erosion. There are a variety of methods to control and manage the impacts of flooding, with key actions including stop-banks, gravel extraction and managing vegetation within the active channel. In addition, various forms of bank protection are routinely employed to prevent erosion, such as rock walls, groins or managed willows. While these techniques can be effective at reducing flooding and erosion risk, they can have negative impacts on river health. Impacts include altered hydrology, reduced habitat complexity and reduced connectivity with floodplain habitats (e.g., riparian areas and floodplain wetlands). Collectively, these effects can reduce fish and macroinvertebrate habitat quality with flow-on consequences for overall river health.
In this webinar I discuss the potential ecological impacts of river engineering (for flood control) and pair these impacts with potential actions to minimise and/or mitigate instream ecological impacts. I will draw on the general river management literature and reflect on my recent experience in the Hawkes Bay region. Here I was involved in developing an ecological monitoring plan, with HBRC, to help manage the potential ecological effects of gravel management in the braided rivers of the Heretaunga plains.

Estuaries are coastal waterbodies where freshwater meets the ocean. They host a diversity of flora and fauna, act as conduits for migratory species, and are transition zones where transformations of energy and matter occur. In addition to their ecological importance, estuaries are places of significance for the people of Aotearoa, delivering substantial economic and cultural value. This talk will review key ecological functions in estuaries and how they translate to goods and services that we value. The influence of land-based contaminants delivered to estuaries via freshwater and the difficulties of managing these ecosystems will also be covered.
Presenter: Drew Lohrer, Principal Scientist and Strategy Manager, Coasts & Estuaries Centre, NIWA
Dr Drew Lohrer has been working as an estuarine and coastal seafloor ecologist at NIWA since 2002, and is now Principal Scientist and Strategy Manager of NIWA’s Coasts & Estuaries Centre. Drew’s research specialty is ecosystem functioning—how seafloor invertebrate communities influence important ecosystem processes such as primary production and organic matter breakdown—and how loadings of sediments and nutrients from land impact estuarine health and functioning.
