Corinne runs BoundarylessNZ, a research consultancy specialising in social science within social-ecological systems (SES). Her passion is to investigate the role of different types of values and worldviews, including Indigenous, in environmental governance and management of food systems. Social science has been increasingly recognised as key to addressing environmental issues, especially as different groups with diverse values and aspirations often engage with each other in the same natural environments.

The aim of Corinne’s PhD research, which she completed in 2020, was to identify how kaitiakitanga (Māori environmental guardianship) might be supported to help reverse the decline of Aotearoa New Zealand’s biodiversity. To do so, she investigated social-psychological factors influencing environmental decision-making by tangata tiaki (Māori environmental guardians) and three stakeholder groups (landowners, Crown institute members, and hunters) associated with wetland ecosystems. Corinne wanted to know what issues might prevent these diverse groups from realising their values and aspirations regarding wetlands (e.g., diverging management priorities between groups).

Originally from Normandy (France), Corinne lived in the UK for 15 years where she worked as an Account Manager in the print industry, before moving to Aotearoa and returning to university to study psychology. She has been living in Ōtautahi Christchurch with her partner and two children since 2008. She holds a BA (Hons) in Applied Languages from the University of Caen (France), and a Grad Dip Sc in Psychology, Master of Science in Applied Psychology, and PhD in Management from the University of Canterbury (Aotearoa).

NZ Humates Ltd was born in the beautiful Bay of Plenty, New Zealand. We are leading the drive to improve the quality of our soil, enhance yields and nutritional value for farmers, and reduce our impact on the environment. We committed to a world where farmers get the best out of their land, where soils are rich in nutrients, where waterways are brought back to life through the containment of nitrates, and where carbon is captured from the atmosphere and stored in the soil.

NZ Humates has access to some of the highest quality raw humates in the world, and we are fortunate to be able to develop this into some excellent liquid products and provide them to farmers and horticulturalists throughout New Zealand. Our humates is rich in fulvic and humic acids and is a significant source of carbon. Our products can help farmers build up their soil organic matter, thereby increasing water holding capacity, holding more nutrients in the soil for uptake when the plant requires it, and significantly reduce leaching.

We’re extremely proud to be another innovative New Zealand company playing our part assisting farmers to improve their soil, provide higher quality food to the people and be sustainable guardians of their land.


Wondering how to deal with cow infections when certified organic? Looking for more ‘tools in the organic toolbox’? The True Health remedies come from Dr Paul Dettloff, senior consulting vet for the 1400 NOP certified dairies in the USA Organic Valley milk cooperative. Dr Paul has developed these plant based remedies over the last 35 years and they are now used on thousands of farms and by dozens of veterinary practices throughout the USA. The 17 True Health Ltd. products are BioGro certified and ideal for naturally and powerfully dealing to the major animal health and calving challenges.The remedies can boost natural animal immune response to help fight off infections and heal minor wounds and skin conditions. They may also be helpful with post calving problems, calf rumen health and hormonal balance in cows. They include: alcohol tinctures, or essential oil extracts, aloe based liquids, udder oils, and boluses. Above all, Dr Paul stresses the importance of good soil remineralisation so that high quality pasture nutrition supports cow growth, production and health. These medicinal plant remedies are a bridge to better animal production as we all strive for minerally balanced soils, high brix pastures, contented animals and a healthy environment.


Better water, better pasture, better health

Hydro Boost increases grass growth by using a low frequency radio to energise water as it passes through the unit. The energised water increases nutrient uptake, water viscosity and enhances root system development in plants.

Hydro Boost stimulates the electrochemical activity of molecules, prevents the formation of scale and dissolves the minerals normally contained in water, allowing them to be absorbed more quickly. In plants, it increases their natural immune system, enhancing the root activity and stimulating the process of photosynthesis, increasing the absorption of CO2 from the air.

Through regular use of Hydro Boost, pasture quality is improved, and growth is maintained during dry periods, while reducing the amount of irrigation required.

The benefits of Hydro Boost can be applied across three areas: pasture growth, water quality and animal health.

Soil to soul: bringing soul to soil.

The soul of the soil is all that lives an moves within the soil. We work with Biodynamic practices. By working with these we can increase the Brix reading that gives an indication of photosynthesis in the plant. increasing the uptake of light by the plant also helps the plant nitrates and simple proteins to complex proteins that are more nutritious to our domestic animals. We and they need eight essential amino acids when they are mature and nine while young.

The increase in sugars feed the soil food web that in turn enable the plant to choose what it needs and when.

Biodynamic practice also includes the right ratio of shrubs and trees for your situation to nurture via self medication, and extra fodder. This practice also increases the comfort to animals and by reducing the wind-flow increases the value of carbon dioxide for the next round of photosynthesis and reduces what is otherwise lost to the atmosphere. Both soil carbon as humus and trees well placed keep the soil cooler in summer so increasing the time that soil biology can be fully active. These are not the only potential benefits. We are happy to join with you as part of your farm team. We look forward to hearing from you.

We work with soil tests and balancing of the elements in soil and plant.

Ewan Campbell is the proud creator of Probitas – a blend included in the fertiliser prescribed and created specifically for your farm, that improves the electrical activity of the soil. Being a farmer himself Ewan also has an deep understanding of the issues farming and agricultural sector today understanding the effect of long term practices which have resulted in falling KPI’s, rising toxicities in the soil.

But it could be Ewan’s desire to be a ‘lazy farmer’ that has helped him develop a multi approach style to fertiliser blends that are only applied ONCE A YEAR. Then left alone. This is the hardest thing the farmer has to do – sit on his hands and let the system do it’s job!

So while you now have time to go fishing or play golf, you can also remember the cost effectiveness that Ecofarm Aotearoa have provided in their blends specific to your farm. There is no guess work, just science. And organic at that.

Vitus is our famous blend of five ingredients designed to assist with making available a full range of minerals in a bio-available form. Three of these ingredients originate from the ocean. All ingredients are blended and bagged in their natural state, exclusively at the Paeroa plant.

Get your farm back to it’s productive past, it’s nutritive heyday all the while knowing that you are improving the environmental impact. And with depots in the North and South Island it is easier than you might imagine! Ewan even wrote a book about it!


Understanding how the microbes effect soil health requires a detailed knowledge on what organisms exist in the soil, how many of them are active, how efficient the nutrient cycling capability is and if the balances are correct for the crop grown.

At SFI NZ, the team assesses soil, compost, compost tea, leaf colonisation, vermicast and various other biological products for fungi, bacteria, protozoa, and mycorrhizal fungi. Armed with this information you are then able to confidently decide on the right management tools plus weigh up how effective they are over ensuing years. Working with many input suppliers and consultants we are able to adapt the farmers existing nutrient program to facilitate a smooth transition from ‘mineral-only’ replacement to biological production.

By maintaining an annual monitoring program, the transformation is able to progress at the same rate as the farmers understanding and confidence.

The biological solution for all your soil and animal health needs

Southern Humates offers you the very best in soil and animal health for your farm. Using nutrient-rich humate from a unique humate stream in Southland, Southern Humates have consistently high levels of humic acid in its products. Southern Humates is backed by scientific research, has been independently tested and is certified for organic input.

Humic acids are essential to life on earth and when they become depleted through modern farming practices, soil problems develop resulting in poor performance of plants and stock. Southern Humates stimulate microbial activity within the soil, which increases bacteria and fungi levels, leading to improved plant quality, better yields and greater productivity.

Not only do Humic acids benefit the soil, but they are also equally important in boosting stock health. The humic acid in our humate along with the high levels of carbon aid an animals ability detox when facing a disease challenge. The carbon in humates absorb any toxins your animals may encountering and cause them to be discharged via the digestive tract. Particularly in the situation of calf rearing, farmers are finding that by having humates available as a loose lick, prevention is better than the cure.


Biosea is a range of innovative biological inputs designed to support growers with their requirements in agriculture and horticulture. Our Biogro number is 202 which should give some indication of how long we have been involved in organic farming in New Zealand.

For the past 30 years we have been involved with 3 of NZ’s largest fishing companies. Our work has centered around liquid fertilisers using fish proteins, seaweed and omega 3 fish oils. We also have unique access to fish meal and mussel meal in solid form.

In addition to fertilisers, animal health has always been a focus. Working closely with farmers over time we have designed a number of animal health products including Biosea Animal Tonic and Biosea Dairy Oil.

Our Biological Solutions Contego range incorporates the use of beneficial fungi and bacteria for plant health and nutrition and pest and disease management. We specialise in mixing the required biologicals with the liquid fertilisers to create a one-pass product for easy application. The Contego range can be supplied separately in powder form to apply where and when necessary. It can be sprayed or used as a wet or dry mix for seed treatment. Each order can be tailored to the growers requirements. 

If you want to improve your soil biology and further develop your organic farming practices then we can help you.
