In the last five years, he has conducted regenerative trials on kiwifruit orchards to scientifically demonstrate that adopting regenerative practices can improve soil health and increase biodiversity, while remaining profitable.

Pranoy will present some key findings of the regenerative trials over the years and identify the main barriers to the adoption of these practices by the kiwifruit growers.

The session offers practical, real-world insights for growers wanting to apply sustainable and regenerative practices on orchards and farms.

LandWISE Conference 2026

Havelock North Function Centre
27 – 28 May 2026

Our “Soil Health for Profit” theme in 2026 is, in some ways, a return to the past. LandWISE arose out of work to combat soil erosion through use of minimum tillage and we’re returning to strip-till in 2026. A lot has been learned in the intervening years! Along with that, we’ll look at what can be done to measure and manage crop nutrition and soil health to ensure sustainability and long-term profitability.  

We have international speakers from Pennsylvania and Tasmania complementing national and local growers and experts. They will share how they set out to build profitable enterprises with a focus on soil health and an eye to wider sustainability ambitions. We’ve asked them to offer ideas of things to take home and apply or try – to feed the appetites of keen delegates.

We have talks from people applying regenerative principles in cropping, pastures and orcharding, talks on strip-till and crop-stacking, soil amendments and cover cropping, and managing and minimising the cost of nutrients. As always, expect representation of agritech covering a wide range of technologies.

Remember to sign up to get updates!

Session Synopsis

Growing multiple vegetable crops across a farming operation the size of Harvest Moon requires constant decision-making, careful timing and a deep understanding of what crops need at every stage of growth. In this session, Josh will walk through how Harvest Moon manages nutrient applications across more than a dozen crops using a combination of field experience, soil and sap testing, and modern data tools.

He will explain how the team schedules and calculates nutrient inputs throughout the season, how they identify inefficiencies in the system, and how these insights feed into broader Integrated Pest Management strategies. By continually measuring and refining what happens in the field, Harvest Moon is able to reduce risk, improve crop health and optimise yield.

The session offers practical, real-world insights for growers looking to sharpen their nutrient strategies, improve efficiency and get more value from the data already available in their farming systems.

Lessons for the management of highly productive land

Two years after Cyclone Gabrielle devastated the Hawke’s Bay and Tairawhiti regions, what have we learned about recovery?

Cyclone Gabrielle struck New Zealand in February 2023, causing widespread flooding that affected Hawke’s Bay, Gisborne/Tairawhiti, and Northland. In Hawke’s Bay and Tairawhiti, Cyclone Gabrielle was characterised by the enormous amount of sediment that was deposited on some of the county’s most highly productive land.

It was an extraordinarily difficult year characterised not by a single catastrophic event but by cumulative impacts from severe storms and several additional weather events including Cyclone Hale in January, Cyclone Gabrielle and Son of Gabrielle in February, and others that followed particularly in the Wairoa and Tairawhiti areas.

In November 2025, we co-hosted with FAR and Vegetable Research and Innovation, a symposium for researchers to share and compare findings from studies of Cyclone Gabrielle and recovery. Around 60 people gathered in Havelock North for two days. Thank you to all the organisations that sponsored the symposium, allowing it to be run with no fees for the participants.

A great deal of semi-coordinated activity followed in the wake of Cyclone Gabrielle. However, there was much incomplete work that would add value by helping enrich our understanding of the longer-term effects of different management responses in different scenarios. The symposium brought together those who investigated Cyclone Gabrielle’s impacts on highly productive land. They presented and discussed findings and observations to draw out lessons to aid land managers and policy makers in future events.

Among the questions were:

1. What are the lessons to pass on to those impacted by future events?
2. What are the lessons for policy makers?
3. What are the economic outcomes from different approaches?
4. How have sites responded to different management of cropping soils, given different sediment types and depths?
5. How have sites responded to the removal of sediment and any subsequent soil amelioration efforts?
6. Have permanent crops responded differently to different approaches applied in similar scenarios?
7. Are all soils recovering quickly? Will they return to previous productivity levels?

Twenty presentations covered historic storm events of note, the weather conditions before and during the cyclone, geological influences, immediate responses, food safety, and longer-term trials seeking to understand how best to return high value land to best production. We thank all the presenters for telling their stories, and all delegates for their contributions to the discussion.

At the end of the symposium, Dirk Wallace led a feedback session in which all delegates responded to a set of questions:

1. What elements aided recovery and what lessons can inform policy and sector planning?
2. What surprises and challenges emerged during recovery?
3. What key takeaways should guide future preparedness?
4. What information is still missing?

Across questions, several themes consistently emerged.

• Communication and collaboration were identified as critically important.
• Data and research surfaced as both a strength and a challenge.
• Infrastructure and preparedness were recurring concerns.
• On the technical front, soil and crop recovery exceeded expectations, with yields rebounding faster than anticipated.
• Finally, human and social dimensions were central to recovery success. Mental health support, patience, and direct communication with experienced peers were repeatedly stressed.

Participants agreed on several priority actions:

1. Establish a central information hub with regional portals to provide consistent, accessible guidance and data.
2. Commission targeted research on rainfall patterns, soil microbiology, contamination risks, and crop-specific recovery timelines, delivered in decision-ready formats.
3. Strengthen pre-event coordination through drills, contact lists, and local decision-making authority, alongside investment in backup infrastructure.
4. Embed human-first supports, including mental health services, peer advisory panels, and tailored financial relief for vulnerable growers.
5. Integrate disaster risk reduction and nature-based solutions (e.g., wetlands, “room for rivers”) into long-term land-use planning.

The symposium captured invaluable knowledge that will help communities and policymakers prepare for and respond to future events. Visit the Cyclone Gabrielle Research Symposium page to access all presentations, with videos coming soon.

Thanks everyone! Sally Anderson, Dirk Wallace and Dan Bloomer – Symposium Convenors

In November, we co-hosted a research symposium with Vegetable Research and Innovation and the Foundation for Arable Research. The symposium brought together those who had investigated Cyclone Gabrielle’s impacts on highly productive land to present and discuss findings and observations, and draw out lessons to aid land managers and policy makers in future events.

A great deal of semi-coordinated activity followed in the wake of Cyclone Gabrielle. However, there was much incomplete work that would add value by helping enrich our understanding of the longer-term effects of different management responses in different scenarios.

The symposium brought together researchers, advisors, farmers/growers and others involved in observing the impacts on productive land and the effects of different responses in the cases of Cyclone Gabrielle and previous similar events. More than 20 presentations covered historic events, the broader climate context of Cyclone Gabrielle, a range of land use types and many areas of research.

The convenors (Sally Anderson, Dirk Wallace and Dan Bloomer) are now in the process of collating the proceedings and preparing to load material on the conference web page. We’ll do posts as items are loaded with abstracts, summaries and presentation videos. From the outset, the response to the calamity that was Cyclone Gabrielle has been one of high support and collegiality from many, many quarters. The symposium was our attempt to get the best from all the work that was done and find the lessons for those impacted by future events.

We are most grateful for the support and enthusiastic involvement of all the presenters and delegates and the organisations that funded the event.

The LandWISE Conference, Getting to Carbon Positive, attracted more than 80 people who heard speakers on a wide range of topics related to ongoing sustainability.

Day 1 discussed ways to assess our emissions levels, how we can reduce our environmental impact through diverse farming techniques including regenerative practices and soil health, and new research around pest management.

Pii-Tuulia Nikula opened with an introduction to emissions accounting, which was followed by Uttam Floray outlining how Toitu certifies emissions. Ron McFetridge from WaterForce said he was asked by key clients about WaterForce’s emissions, which set them on a journey to reduce their emissions and environmental impact. Olivia’s take:

“I enjoyed listening to Ron discuss how WaterForce has been installing solar panels on their offices, putting in electric vehicle chargers, and deploying electric and hybrid vehicles for their staff. Given that they travel 4.5 million kilometres annually as a company, WaterForce saw electrification as an effective way to reduce emissions and environmental impact. By doing this, they are setting a precedent for other companies.”

Dan Bloomer presented results from the Carbon Positive trial including the 2024-2025 cropping programme and a Carbon balance for each of the treatments, which showed nitrogen fertilisers and diesel were the largest CO₂^-e contributors. The introduction of livestock added significantly to overall emissions, even if on farm for a relatively short time. Matt Norris presented results from regenerative cropping trials, including use of composts, at LeaderBrand in Gisborne, Angus McKenzie described how Wairuna Farm is applying the principles in Canterbury, the various things he had been trialing on his farm, and how they created a wetland to treat drainage water. Sam McNally addressed ways to increase soil carbon and explained fundamental changes in our understanding of soil carbon sequestration and carbon pathways. Photosynthesis feeds the whole system!    

Three speakers discussed beneficial non-crop plants. Dan talked about the lessons from growing multispecies cover crop mixes in the Carbon Positive trial. Charles Merfield provided information about cover crops for regenerative cropping and the need to ask what functions you wanted cover crops to perform. Jeff Smith presented lessons from biostrip and insectaries research through the A Lighter Touch project.

Day 1 was wrapped up with Asha Chhagan talking about new technologies to assist pest and disease management, and Bethan Shaw reporting on work done looking at earwigs recolonising orchard sites that had been devastated by Cyclone Gabrielle. Daniel Sutton and Chris Lambert reporting on trials with a camera equipped AI enabled pest trap.

Olivia’s take:

“The conference was a good opportunity for me to do my first conference presentation! I talked about the Slakes app and things we have learned from using it to assess soil aggregate strength, and I spoke about the Nitrachek device project that I have been running as a part of my Te Ahikawariki/VICE internship.”

Many thanks to all our sponsors, speakers and delegates!

The LandWISE Conference, Getting to Carbon Positive, attracted more than 80 people who heard speakers on a wide range of topics related to ongoing sustainability. Day 2 had a strong focus on electrification options to increase profitability and reduce emissions. New Zealand is reaching a point where solar power is the cheapest energy available – as Mike Casey noted, the cheapest form of energy ever.

Uttam Floray introduced Rewiring Aotearoa and the local chapter, Electrify Hawke’s Bay which are focused on helping promote and activate electrification. Mike Casey described the electrification of his cherry orchard and laid out a huge set of statistics and examples of ways New Zealanders can profitably swap fossil fuel machines for electric ones. Becks Smith now helps farmers work out how solar can add to their businesses having set up a solar system for irrigation pumping in Otago.

Lincoln University has chosen major investments in solar electricity to reduce emissions at the university, and Pieter-Wilem Hendriks is part of a team investigating ways to combine agricultural production with energy generation. At smaller scale, Aaron Duncan explained options for home and SME solar systems, using the Centre for Land and Water system as a case study. Boyd Benton discussed the way Ripple Tech transplants electric motors into fossil vehicles and, in a second talk, introduced micro-hydro as a viable option for sites with streams. Olivia said

“It was fantastic to hear Uttam Singh Floray, Mike Casey, Becks Smith, Pieter Hendriks, Boyd Benton, and Aaron Duncan discussing electrification and reducing emissions. You could sense their genuine passion for the topic, which made their talks even more engaging. I particularly enjoyed Mike Casey’s talk on his electric cherry farm. I found it fascinating that every piece of machinery used on the farm is electric, including the truck that transports the cherries to the packhouse. That means there are no fossil fuel carbon emissions until after the cherries have been transported from the farm.”

Horizons Regional Council Field Session

The field session on Thursday afternoon provided delegates with opportunity to get first-hand experience of some of the techniques and technologies that had been discussed. We thank “A Lighter Touch”, WaterForce, Freenergy, RippleTech, PowerSpout, Vegetables NZ, Autonabit, and Agovor for bringing their wares to demonstrate. Gadgets, machines and systems to excite, save time and money, and enable systemic changes. Olivia said

“I didn’t make it around to all the field event demonstrations, as I was demonstrating the Slakes app and the Nitrachek device. I did manage to see the smart trap, the off-grid hydro pump, the Govor robot, and the Avvy bird scaring robot. They offer so much, and we expect to see a lot more of these technologies in years to come!”

We gratefully acknowledge all our sponsors, presenters, demonstrators, and delegates!

Getting to Carbon Positive

Wednesday 21 – Thursday 22 May
Havelock North Function Centre

In 2025 we’re delighted to bring you a conference with focuses on regenerative crop production, carbon footprinting, and electrification. We’ll have new technologies to think about and see, we have speakers with proven track records, and we’re looking forward to catching up with old friends and new.

Do we know the footprint of our activities? How do international markets assess them and what will we need to report? We are proud to present Associate Professor Dr Pii-Tuulia Nikula to open the managing our footprints conversation. We’ve done the numbers on our Carbon Positive cropping treatments, and we’ve others talking about what they are doing to address their footprints too.

If we are going to get to Carbon Zero (or better) we need to think about both inputs and outputs from our systems. Can we soak up more than we lose? Which inputs have the greatest impact?

We will report on progress and lessons from another year of our regenerative cropping research and present some new tools for growers to assess nitrate levels and soil stability. We’ll have examples for viewing at the Horizons Regional Council Field Session. Others will update us about new technologies for pest and disease control and reintroducing insects to cyclone impacted orchards and discuss the use of bio-strips and insectaries to encourage beneficial insects.

We’ll need energy, of course, but how much can we generate on-site? Is electrification realistic now? Where to in the short to medium term? We are delighted to have Mike Casey of the Electric Cherry Orchard and CEO of Rewiring Aotearoa opening the discussion on electrification and alternative energy case studies. We’ll have electric vehicles for perusal.

Thanks to our Sponsors!

We look forward to seeing many of you again in 2025.
