The 1941 gardening club that owns New Zealand's organic logo

The BioGro sticker on your kiwifruit belongs to a gardening club.

Not a corporation, not a government agency. A charity that started in Auckland in 1941 as the Humic Compost Club, when wartime shipping cut off fertiliser imports and people had to work out how to build soil fertility without a bag of anything. It is one of the oldest organisations of its kind anywhere in the world, and it is still going, under the name the Soil & Health Association of New Zealand.

I went looking for it because I wanted somewhere to keep up with organics here that was not a brand's own marketing. What I found is smaller and more interesting than I expected.

What it is now

A charity and incorporated society, run by a volunteer National Council of seven, with one part-time administrator. That is the whole organisation. Everything it puts out is made by people doing it around their actual jobs.

It publishes at organicnz.org.nz, and sends a monthly email newsletter to anyone who signs up. The newsletter was called The Good Dirt until recently and now carries the Organic NZ name, which caused me about twenty minutes of confusion and is worth knowing if you go searching for it.

For decades the main thing it made was a print magazine, six times a year, sold in supermarkets and Paper Plus. That ended in 2024. The reason is unsentimental: it cost around twenty dollars to produce a copy with a face value of $9.90, and close to half the retail copies came back unsold and were pulped. Members voted at a special meeting in May 2024 to stop. Anyone who has ever tried to fund good writing about food will recognise that arithmetic, and probably wince at it.

So the website and the email are what carry on.

What is actually on there

The moon planting calendar, which comes out every two months and draws on biodynamic practice. Use it or don't, but it is one of the few places you will find it published regularly in New Zealand.

Seasonal produce columns, one fruit or vegetable at a time as it comes in: passionfruit, mandarins, feijoas, strawberries, cherries. These lean toward nutrition, growing tips and recipes rather than how the crop is handled after picking, which is the part I tend to chase, so I read them for the other half of the picture.

Research summaries, where someone has gone and read an agricultural science paper so you don't have to. A recent one covered a trial finding that worm farm liquid combined with mycorrhizal fungi grew better head lettuce than compost on its own.

Then the things that are not articles at all: branch meetings around the country, Organic Week each May, the annual awards night, wall calendars in December, and film screenings. They put on twenty screenings of a soil documentary in one year and got over five hundred people through the door, which for a volunteer outfit is not nothing.

A useful chunk of it is free to read. The rest sits behind membership.

The BioGro connection

Here is the part that surprised me. In 1983 Soil & Health, together with the biodynamics people and the Henry Doubleday association, set up a certification body so that "organic" on a label meant something checkable. That became BioGro. In 2016 the two organisations merged, and Soil & Health became its owner.

So the sticker you already recognise on kiwifruit, wine and pip fruit, on roughly nine hundred certified operations, traces directly back to the compost club. That is a longer thread between a shopper and a 1941 committee than I expected to find in a food label.

Is it worth joining?

If you want organics in New Zealand to have an organised voice, membership is the straightforward way to be counted. The Association makes submissions on things like glyphosate, chlorpyrifos and gene technology, and it sits at the table when the government writes the rules. Joining is what puts a number behind that.

If you just want the reading, the free articles are a fair sample of what the members-only ones are like, and the monthly email costs nothing. Start there and see what turns up.

Either way, someone has been keeping this going for eighty-five years. Worth an email address.

As at August 2026.
