Is Your Manuka Honey Real? What the Research on Manuka Fraud Means for Buyers

If you’ve spent money on Manuka honey and felt uncertain about whether you got what you paid for, that instinct is worth taking seriously.

Manuka honey fraud is real, well-documented, and ongoing. Studies have found Manuka honey sold in the UK, US, and across Asia that contained little to no genuine Manuka markers. One widely cited analysis found that the volume of honey sold internationally as “Manuka” far exceeded New Zealand’s total annual production — which means a significant proportion of what’s on shelves around the world cannot be what the label claims.

This guide explains what’s happening, how to protect yourself as a buyer, and what genuine certification actually verifies.

The commercial incentive is straightforward: Manuka honey commands a significant price premium over regular honey. The gap between the cost of bulk blended honey and the price of premium Manuka creates an obvious opportunity for mislabelling.

The specific problems take a few different forms:

Blending and dilution. Genuine Manuka honey is blended with cheaper honey and the resulting product is still labelled as Manuka. The buyer is getting a fraction of what they think they’re buying.

Inflated grades. A batch of honey is sold at a higher UMF™ or MGO grade than the testing actually supports. Without independent verification, there’s nothing to stop a producer from printing whatever number they choose.

Non-Manuka honey sold as Manuka. In some cases, honey with little to no Manuka-origin markers is labelled as Manuka and sold at a premium. The label bears no relationship to the contents.

Unclear origin claims. “Manuka honey” is sometimes applied to honey from sources outside New Zealand, or to honey with only a partial botanical claim to genuine Manuka origin.

New Zealand’s annual Manuka honey production is approximately 1,700 to 2,000 tonnes of certified export-grade product. Estimates of Manuka honey sold globally are several times this figure.

The maths don’t work. A meaningful portion of what is sold as Manuka honey globally cannot be genuine.

This is not a fringe concern. It has been raised by the New Zealand government, by the UMF Honey Association, and by food standards bodies in the UK and EU. Enforcement has been patchy and international standards have historically been inconsistent — though New Zealand has tightened its own export standards significantly in recent years.

This is where genuine certification creates a clear line between verified and unverified products.

The UMF™ certification system tests three specific compounds that are unique to genuine Manuka honey:

Leptosperin. A compound found only in Mānuka nectar. If leptosperin is present at the required level, the honey demonstrably came from the Mānuka plant. It cannot be faked or added because no other plant produces it and it cannot be synthesised in a way that passes accredited testing.

DHA (Dihydroxyacetone). A precursor to MGO that naturally occurs in Mānuka nectar. Its presence confirms that the MGO in the honey developed naturally from genuine Mānuka nectar, rather than being added separately.

MGO (Methylglyoxal). The most commonly discussed Manuka marker. Measured and recorded as part of the full UMF™ assessment.

Because all three are tested together by an accredited laboratory — and because the results are issued independently, not by the producer — the UMF™ mark represents the strongest available verification of genuine Manuka honey.

Look for the UMF™ mark. The UMF™ logo is trademarked. A jar carrying it has submitted each batch for independent laboratory testing. A jar that only shows the letters “UMF” without the official mark, or that displays only an MGO number, has not been through the same process.

Ask who owns the hives. Many Manuka honey brands source bulk honey from processors and apply their own label. That’s legal, but it limits traceability. The most transparent producers own their hives and can trace every batch back to a specific region, season, and hive location.

Check for a batch number. Genuine UMF™-certified Manuka honey is batch-traceable. At Happy Valley, you can trace your jar to the specific batch using the number on the label.

Verify New Zealand origin. Genuine Manuka honey comes from New Zealand. If origin is unclear or vague on the label, treat it with caution.

Check the UMF™ licensee list. The UMF Honey Association publishes a list of licensed producers. You can verify whether a brand is a current licensee at umf.org.nz.

We have owned and managed our hives in New Zealand since 1984. We extract honey in our own facility. Every batch is independently tested and UMF™ certified before it leaves us. The grade on the label was assigned by an accredited laboratory, not by us.

You can trace your jar. The batch number on the label connects to our testing records. That traceability exists because we control every step of the process — from the hive to the jar — and because we’ve built the infrastructure to maintain it.

This isn’t a selling point we invented. It’s the natural result of being a beekeeping family that grows the product rather than a brand that sources it.

• UMF™ logo is present (not just letters)
• Grade number is displayed alongside the logo
• Batch number is on the label
• New Zealand origin is stated clearly
• Producer is on the UMF Honey Association licensee list

If a jar you’re considering doesn’t meet these criteria, it hasn’t gone through the same level of independent verification.
