Here is a list of our approved suppliers who support ODPG. For more information please see each individual entry. If you wish to be included in this list, please contact us.



UNITED FISHERIES LTD is one of New Zealand’s major fish processing companies, based in Christchurch.

We source our fish from New Zealand’s crystal clear waters, and our aim is to help keep our waters clean and crystal clear.

Wild caught fish (a Sustainable Fishing Resource harvested according to the New Zealand Quota Management System), is processed in our purpose built facilities, and the offal is enzymatically hydrolysed to produce Bio Marinus™ Liquid Fish Fertiliser, retaining the proteins, fish oil, amino acids, naturally occurring vitamins and enzymes.

Bio Marinus™ is Mother Nature’s fertiliser, a blend of multiple nutrients and trace elements from the sea that even Empedocles, the Greek father of chemistry, would have been proud to create.



Biostart has been quietly getting on with solving productivity issues and improving sustainability through harnessing naturally occurring microbes for the last 25 years. We believe the key to productivity lies in keeping soil, plants and animals in optimal health. This, along with an early dedication to sustainability followed with extensive trialing, now puts Biostart in the position of being able to provide primary industry with reliable and sustainable products that both improve productivity and help protect our environment at this time of crucial change. 


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.

Kiwi Fertiliser Co Ltd.

We specialise in bringing top soil fertility to all and any farmers and growers, New Zealand-wide. It is our aim to change the face of New Zealand agriculture which requires huge improvements.

We exist because some of the fertiliser companies have failed to deliver real fertility to farmers, who demand and deserve better treatment. Soil fertility is not about selling products the fertiliser companies produce. It is about meeting the exact requirements tailor made for each property, or parts of properties.

We make recommendations from soil tests sent to USA. The results we get are outstanding.

Let me help you tailor regenerative grazing to your situation and teach you how to get optimal animal performance. I also help clients create grazing strategy for their individual farm in a New Zealand context.


When you are ill, you go to a doctor. Like your body, your farm is a complex ecosystem that needs regular expert attention and “checkups.”

While agriculture suppliers are usually helpful and can be a good source of information, their focus is on the products they offer and make money from.

At Integrity Soils our team of consultants specialises in biological farming systems and their management. For over 15 years, we have been helping, teaching and inspiring farmers, ranchers and the organisations that support and supply them.

Succession – Opening Minds to Opportunity

If you want to lower farm production costs and lift farm profitability then read on…

Succession events train farmers to manage sustainable businesses. These events explore how families, money, and technology come together to make businesses and properties successful. Using new insights, farmers and their families create practical and profitable ideas for working with land and managing farm businesses.

John’s passions are education, environment, and entrepreneurship. Farm practices need to regenerate soils, lift profits, and lower labour, the new triple bottom line. The services John provides help farm families and businesses develop confidence to try new ideas and achieve these outcomes. Emphasis is placed on observation, monitoring, and analysis, a learning process that makes farmers proactive in pursuing their dreams. These techniques draw on John’s experiences as a certified Holistic Management® educator and his direct access to the Holistic Management global network.


BIOSEA has been in a JV with The Sealord Group for over 25 years, producing concentrated liquid fish fertiliser with the highest protein level available in NZ (32 – 35%). Our BioGro number is 202, indicating just how long we have been working with organic farmers. 

We also supply a range of beneficial bacteria and fungi for soil health and pest and disease management. At Biosea we’re focused on plant and animal health and providing cost effective biological solutions.  


At 5th Business Agri we’re passionate about stock wellness. We all agree that we are what we eat, and the same applies to our livestock. Analysing our diet for mineral content, particularly our pastures, and understanding the dietary risks can help to achieve optimal animal performance and efficiency.

We have an intelligent farm decision support tool called the DietDecoder that will help you make the best decisions around mineral supplementation and nutrient use on your farm.

We can work with you or your trusted advisor and will add value to your business.

Fun Fact: It’s estimated that we could achieve about a 10% reduction (below baseline) in absolute agricultural emissions through enhanced animal performance. Animal efficiency is something we can improve on right now and this starts with understanding our pastures. We look forward to having a chat.


The Ecofarm Aotearoa Systems Soil Management Programme

Ecofarm Aotearoa has developed a soil management programme that is designed to allow the unimpeded function of soil, soil biology and plants, and to provide the information that is required for accurate, cost effective intervention when required. The Ecofarm Aotearoa soil management system incorporates the following components of nature:

  • Soil Mineralogy
  • Soil Biology
  • Soil Electro-magnetic Energy
  • The Soil / plant Nutrient Cycle


The Ecofarm Aotearoa soil management program is designed to reinstate the natural functions of the sun, soil, soil biology and plant energy cycle and, in conjunction with appropriate environment management the program will result in nutritious crops, healthy productive livestock and the creation of food that is fit for purpose from a production system that maintains the environment and keeps councils happy.


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.


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.


Nutrients for Soil Health

For more than 70 years, Avoca has been supplying Northland farmers with expert advice and top quality agricultural lime and fertilisers to ensure better crops and healthier livestock.

Avoca Lime Company began in the Tangowahine Valley, just out of Dargaville, selling and transporting lime. Today the company still specialises in lime and fertilisers, but also offers many other products and services, with soil specialist consultants across Northland and in the North Waikato area  offering professional advice on soil fertility and fertiliser management.

NZ Humates Ltd.

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.

Soul to Soil

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.
