Show Notes: From the Lake District to Southland Collective Richard shares his background moving from mixed farming in the UK to the New Zealand dairy sector and his extension work with DairyNZ. Now leading Thriving Southland, he helps provide 37 independent catchment groups with the information and funding resources they need to own and drive their own environmental projects. The Power of Localised Science Generic environmental rules often miss the mark, so Thriving Southland focuses on sub-catchments. Richard explains how using radiometric data to understand specific soil and water dynamics helped one community identify mobile soils as the root cause of an E. coli issue, allowing them to precisely target their sediment management and maximise their return on investment. Integrating Water Quality and Climate Resilience While greenhouse gas emissions can feel like a harder sell on a day-to-day basis, Richard emphasises that climate resilience, farm profitability, and water quality are completely interlinked. Projects like Carbon Neutral Dipton allow sheep, beef, and dairy farmers to collaborate on emissions mitigations and land use optimisation without separate legislative mandates. The Extension Model and Peer Learning The historic success of New Zealand agriculture relies on farmers talking to farmers. Catchment groups foster this extension model, allowing early adopters to pave the way while others observe and catch up. This peer-to-peer approach builds genuine confidence and drives world leading change at a manageable pace. The Value of a Cheese Roll Building wide community engagement is less about rigid dictation and more about social connection. Richard notes that the real wins often happen over a cup of tea and a cheese roll, providing a vital social wellness forum for isolated farmers to realise they are not facing seasonal or regulatory challenges alone. Final Advice: Look Back to Move Forward Richard encourages any farmer curious about their local catchment group to simply put their head in the door without fear of a heavy commitment. True progress is voluntary and takes time. By reflecting on how far practices like winter grazing have transformed the Southland landscape over the last decade, farmers can find the optimism needed to face today's challenges.

In this RaboTalk, Growing our Future episode, host Blake Holgate speaks with Steve Brown, Chief Executive of Headwaters and High Health Alliance, to explore how the breeding and supply programme behind Lumina Lamb connects on-farm decisions directly with top-tier international chefs. Steve outlines how a group of Southland and Central Otago producers established Headwaters in 2007 to solve a fundamental market problem: the lack of consistent eating quality in traditional lamb.
In the first episode of RaboTalk Growing our Future’s new Succession 2050 series, host Blake Holgate speaks with Ray Smith, Director General of the Ministry for Primary Industries (MPI), to explore his contribution to Rabobank’s Succession 2050 Gearing up for New Zealand’s food and agri future white paper. Drawing on his extensive experience leading major public sector departments alongside a family background in agriculture, Ray provides a strategic perspective on how New Zealand’s primary sector is entering a new era of sustainable productivity. Ray discusses how New Zealand producers can leverage their natural advantages to capture growing global demand for high-value protein and nature-positive products. He outlines how unlocking productivity, investing in regional water storage, adopting emerging precision technologies, and maintaining rigorous biosecurity and farm assurance schemes will secure the sector’s long-term global competitiveness out to 2050.
In this fifth episode of RaboTalk’s Growing Our Future Catchment Catch-Up series, host Blake Holgate speaks with Mark Chrystall, a northern Rangitikei sheep and beef farmer and founding member and current Vice Chairman of the Rangitikei Rivers Catchment Collective (RRCC). Mark shares how the collective formed in 2017 to tackle localised riverbank feed-lotting issues and evolved into an expansive, data-driven entity. Today, the RRCC coordinates 125 monthly water testing sites and manages projects spanning sub-catchments across the Rangitīkei, Turakina, and Whangaehu rivers. The conversation explores how catchment collectives can build regional trust, transition from raw water testing to advanced ecological indices, and address emerging environmental challenges. Mark highlights how spatial mapping, collaborative university research, and unified pest control projects help hill-country farmers take ownership of their landscapes, protect local freshwater quality, and build resilient rural communities.

Show Notes: Empowering Farmers Through Local Water Testing Rather than relying solely on regional council monitoring, the RRCC established 125 monthly water testing sites across its sub-catchments. Testing for nitrogen, phosphorus, E. coli, and turbidity provides producers with transparent, localised data. Placing these real-time results directly in front of landowners creates instant buy-in and inspires peer-driven environmental improvement. Uncovering Environmental Context via Science In the Waikākahi tributary, monthly testing revealed phosphate levels nearly 20 times higher than expected. Rather than assuming agricultural runoff was the cause, the collective partnered with Massey University and Horizons Regional Council on a three-year PhD project. Geologic analysis revealed the elevated phosphate stemmed from natural rock formations rather than farming practices, illustrating the power of raw data over assumptions. Moving Beyond Single-Metric Water Testing The collective has expanded its environmental monitoring to include Macro-invertebrate Community Index (MCI) testing and habitat assessments across 80 sites. By training local coordinators to evaluate stream life, silting, and aquatic plants alongside regional council teams, the RRCC creates a complete, long-term picture of freshwater health across hill-country catchments. Transitioning from Farm Plans to Integrated Catchment Plans Building on individual Sustainable Land Use Initiative (SLUI) maps, the collective is aggregating farm data into comprehensive digital catchment plans. Layering spatial data for winter grazing, biodiversity, slope, and critical source areas allows the group to move past a scattered approach and direct environmental funding straight to high-priority hotspots. Targeting Hotspots with Infrastructure and Pest Control The RRCC actively tackles non-traditional environmental risks across the region. Projects range from fencing and planting native vegetation below gully wool-sheds to capture nutrient runoff, to launching a multi-regional thermal drone survey to map wild deer populations. Quantifying pest damage on winter forage crops allows the collective to design coordinated, landscape-scale control strategies. Final Advice: Understand Your Footprint and Stay Connected Mark encourages farmers and community leaders to proactively understand their environmental footprint rather than waiting for regulatory mandates. Keeping local sub-catchment groups active, sharing spatial data, and gathering at the local hall for a cup of tea or a sausage sizzle creates the social cohesion needed to navigate future land management challenges together.
This RaboTalk Growing our Future’s episode explores one of the biggest questions facing New Zealand agriculture: how farmers and growers can reduce greenhouse gas emissions while protecting profitability and long-term business resilience. Blake Holgate is joined by Lee Matheson, Managing Director at Perrin Ag and co-author of The Path to 2050 white paper, for a practical discussion on why Lee believes the sector cannot rely on future technology alone, and why he considers emissions planning needs to sit at the heart of farm strategy. In the podcast Lee talks about the importance of improving efficiency, understanding each farm’s emissions profile, making land-use decisions based on sound economics, and working collectively through peer groups, processors, industry bodies and policy settings. The Path to 2050 white paper can be accessed here. Like what you’ve heard? Follow our podcast for more great content.
In this fourth episode, of RaboTalk Growing our Future’s Catchment Catch-Ups series Blake Holgate speaks with Paul Turner from Taranaki Catchment Communities about how farmer-led catchment groups are helping rural communities take practical, locally driven action on water quality, biodiversity and environmental resilience. Paul shares how 18 independent sub-catchment groups across Taranaki are working together to balance on-farm priorities with wider environmental goals, using tools such as 3D Lidar mapping to better understand water flow, identify risk areas and plan effective mitigations like riparian planting, wetlands and detention bunds. Like what you’ve heard? Follow our podcast for more great content. Show Notes: The Farmer-Led Umbrella Structure Formed five years ago to get ahead of complex water quality legislation, TCC acts as the governance and funding vehicle for 18 independent catchment groups. Paul emphasises that the entity remains strictly farmer-led, operating as a politically neutral conduit that translates council compliance rules into practical, stress-free options for the rural sector. Managing the Mountain-to-Sea Landscape Taranaki features a highly unique geography, with water flowing rapidly from the central maunga across the ring plain and out to the coast. This steep terrain creates short, high-altitude catchments. Rather than attempting a rigid, one-size-fits-all approach, TCC accommodates the distinct environmental profiles of local dairy, sheep, and beef producers. Slowing the Movement of On-Farm Water With intense weather events driving large, unpredictable volumes of rain across the region, creating permanent environmental mitigations is challenging. TCC focuses on training farmers to naturally slow water paths by utilising extended grass filter strips, deep riparian plantings, constructed wetlands, and strategically placed detention bunds that filter sediment and lower nutrient loadings. Unlocking Spatial Precision with 3D Lidar Through a collaborative project with the regional council and MPI, TCC has made detailed 3D Lidar contour mapping freely available to every landowner in Taranaki. This advanced remote sensing data highlights exact farm topography, ephemeral streams, flood zones, and critical source areas, putting producers well ahead of the freshwater farm planning game. Connecting Native Eco-Corridors Biodiversity projects achieve far higher community buy-in when they are tied to a collective regional narrative. Paul highlights the Pātea River Catchment Group’s massive landscape trapping network, which aims to bring native kiwi back to the local bush. By establishing green pathways alongside active weed and predator control, farmers are actively creating sustainable breeding grounds for vulnerable species like the Australasian bittern. Silos Broken Down Through Regional Integration Taranaki’s environmental success relies heavily on breaking down institutional silos. An active monthly integration group brings together rural support networks, regional council officers, and major dairy cooperatives to synchronise resources. This collaborative framework ensures training programs are shared efficiently, preventing community fatigue and maximising the return on investment. Final Advice: Capitalise on the Power of the Group Paul challenges farmers and growers to step out from their individual properties and actively join their local sub-catchment collective. Collective action is inherently empowering, providing isolated producers with shared access to plant funding, spatial data, and regulatory support. By working together within a unified catchment framework, communities can move past isolation, support their peers, and deliver visible environmental improvements across the entire landscape.
