It’s important that those of us who care about food quality get our heads clear about why we need organic certification. Recently I’ve been hearing a lot of people dissing organics. Some say, “Organic certification is just too hard and expensive.” Others say, ”Spray-free is good enough for me, I don’t mind because I know the people I’m buying from.”

And not long ago, the Koanga Institute sent round an email with the subject line “Organic vs nutrient dense food”, suggesting that organic growing is only about avoiding toxic chemicals. I respect Kay Baxter’s work, but I believe this is not helpful or accurate.

Organics and nutrient dense are not “either-or” things. In a country where most people can’t buy food directly from producers (or grow it ourselves), we need certification to provide third-party assurance that the produce has been grown to a good standard, and the grower has been looking after the land and in particular the soil. You can’t tell by looking at a cabbage whether it has been grown to organic standards or not. You can’t tell by looking whether a cabbage is nutrient dense, either. (I think sometimes I can tell by taste. But not always.)

Here’s the thing: In order for a grower to be certified organic with BioGro or OrganicFarmNZ, they would have to be actively practicing soil regeneration. Organic growing practices, as outlined in the BioGro standards, are precisely about soil regeneration, which will result in nutrient dense food.

It’s true that some organic certification internationally is about ticking boxes and avoiding toxic chemicals, rather than growing the soil. Michael Pollan has written about this in his 2006 book The Omnivore’s Dilemma. But it doesn’t apply here in New Zealand. Our organic certification does a lot more than scratching the surface of the soil.

BioGro CEO Donald Nordeng has described New Zealand’s organic certification processes as “legacy standard”, meaning they are rigorous and there is a high degree of integrity by international standards.

Four organic certification systems

There are currently four different systems of organic certification in New Zealand. If growers are producing for international markets, then they need to get certification with BioGro or AsureQuality. There’s also Demeter, the international organic certification label for produce grown using Biodynamic practices, following Rudolf Steiner’s philosophy of agriculture. (It’s organic plus much more.)

The fourth option is OrganicFarmNZ. This is a small-scale certification system tailored to the needs of growers producing for local markets.

The three international certification systems are fairly expensive. They have a high degree of integrity, but they can also be quite inflexible, due to stringent international market requirements. Hence we hear horror stories of growers with a huge amount of experience suddenly losing their certification because there was a drought and they had to use animal feed that was “spray-free” but not fully certified organic.

OrganicFarmNZ – small and affordable

OrganicFarmNZ (also called OFNZ) describes itself as a “grassroots” certification system. OFNZ was set up in 1999. The purpose of the organization is to make organic certification affordable and do-able for small-scale growers, producing for local markets.

It costs as little as $300 per year to get organic certification through OFNZ, and this includes a considerable amount of “professional development” – training and mentoring and resourcing in organic growing practices.

OFNZ works to the same standards as BioGro, but the process of certification is very different. Instead of outside experts coming in and assessing, growers join local groups (called “pods”) and participate in peer-to-peer assessment, backed by industry veterans. Because OFNZ doesn’t have to deal with international markets it can be more flexible. Much of the integrity in the OFNZ system comes from local growers supporting each other to improve their skills.

OrganicFarmNZ is accredited internationally with IFOAM, the International Federation of Organic Agriculture Movements, as a PGS (Participatory Guarantee System). PGS are locally focused quality assurance systems, built on a foundation of trust, social networks and knowledge exchange among local farmers worldwide.

If OFNZ is so great, why don’t more people already know about it?

OFNZ operates on a shoestring budget, so it doesn’t have money to promote itself in the media. Also, the horticulture and agriculture industries focus on large companies and high-stakes international trade, where certified organic produce gets a premium return (e.g. dairy and kiwifruit). A certification process aimed at small-scale producers and local markets falls well under the radar. There are no marketers, consultants and advisors “talking up” OrganicFarmNZ.

OFNZ is achievable, inexpensive organic certification for small-scale growers, that still has a high degree of integrity.

Why “spray-free” isn’t good enough.

I want to challenge growers to aim higher than this.

Three reasons:

  1. It’s okay if you know the grower personally and trust them. But, people who live in cities can’t easily go and visit growers. And, we may not know enough about growing methods to ask the right questions. Organic certification gives us accountability via third-party expertise.
  2. The glyphosate/Roundup issue: Many growers who claim to be spray-free may be using Roundup to control weeds, if they’re not well-informed about the multiple, systemic toxicity of Roundup and if they don’t know about organic cultivation practices to avoid needing to use herbicides. They may even believe the company’s marketing, which still claims that Roundup is non-toxic.

The evidence is stacking up against Roundup. Here’s a link to my article on the Waikato Foodbasket about international health research on the impact of Roundup on human health. And here’s a link to the website of Professor Gilles-Eric Seralini, the Italian biochemist who has proved links between Roundup and cancer. I heard Prof Seralini speak in New Zealand last year.

  1. What does “spray-free” actually mean, anyway? E.g. there are many sprays used in organic and regenerative agriculture, including Agrisea’s excellent seaweed spray products, which are made in New Zealand.

If a large-scale grower claims to be spray free, why don’t they invest in organic certification? Possibly because they think consumers don’t care about it. But we do!

Demystifying some of the terms

Certified organic

This means the grower has gone through a comprehensive review process according to one of the organic certification organisations.


“Spray-free” is only as good as the word of the grower. It could mean someone who grows lettuces hydroponically and doesn’t use agricultural sprays (but his produce won’t be nutrient dense, because it’s not grown in living soil). It could be someone who refrains from using toxic agricultural sprays, but is not actively caring for the soil. They might also be using Roundup, because they believe it is non-toxic.

Or “spray free” might mean a grower who is caring for the soil and producing a crop with superb nutritional quality – organic in everything but the certificate.

As consumers of food it is hard to know the difference. We need to tell growers that we do care about the quality of our food. Accepting “spray-free” as good enough doesn’t send a clear message to producers.

Nutrient dense

This refers to the superior nutritional qualities of food that has been grown in soil that has been cared for, which has a full range of micro-organisms and available minerals and other nutrients. Food that has been grown using industrial agricultural methods will be depleted in nutrients. (This is the factor behind research proving that organic food has superior nutritional qualities compared to food grown using conventional agricultural methods.
