Our Beginning

Built on one honey, and one standard.

Haddrell's of Cambridge has produced New Zealand mānuka honey since 1993, sourcing and grading only high-quality, fresh mānuka honey from the country's remote wild backcountry.

Be Elite Ltd is the export partner bringing Haddrell's of Cambridge to international markets — working directly with distributors and wholesalers, so every buyer gets transparent sourcing and accurate costing.

Every batch we export carries its UMF™ licence number, independently verifiable through the UMF Honey Association — so the number on the jar is always backed by a lab result, not a marketing claim.

Where It Grows

Found only where the wild bush hasn't been touched.

The mānuka tree is native to New Zealand, and the areas thick with its blossom sit deep in remote country — some reachable only by helicopter. That's where our beekeepers place every hive.

It's a short, unforgiving season. Bees have only weeks to gather the nectar behind this honey's rare, earthy complexity.

PER YEAR — THE ENTIRE HARVEST WINDOW
Discovered 1981

Forty years of research behind one rating.

The unique properties of mānuka honey were first identified in 1981 by Dr Peter Molan MBE, Associate Professor of Biochemistry at the University of Waikato and researcher at the NZ Waikato Honey Research Unit.

Since then, mānuka honey has become one of the most studied natural foods in the world — a complex substance containing more than 2,000 bioactive compounds, with the Unique Mānuka Factor (UMF™) system now serving as the industry's only independent quality standard.

UMF™ Honey Association

Overseen by the UMF Honey Association in partnership with the University of Waikato Honey Research Unit, the UMF™ mark certifies purity, potency, authenticity and freshness — traceable batch by batch at umf.org.nz.

The Four Quality Factors

What the UMF™ rating actually measures.

Each factor is tested independently and must clear a minimum threshold before a batch can carry its UMF™ number. These are the New Zealand industry's official published thresholds.

Quality Factor UMF™ 5+UMF™ 10+UMF™ 15+UMF™ 20+UMF™ 25+
MGO (Methylglyoxal)Potency 83 mg/kg261 mg/kg512 mg/kg826 mg/kg1197 mg/kg
LeptosperinAuthenticity >100 mg/kg>150 mg/kg>200 mg/kg>200 mg/kg>200 mg/kg

HMF (Hydroxymethylfurfural)Freshness <40 mg/kg<40 mg/kg<40 mg/kg<40 mg/kg<40 mg/kg

Source: UMF Honey Association published grading thresholds. MGO gives mānuka honey its antibacterial strength; Leptosperin is unique to mānuka nectar and confirms genuine origin; DHA converts to MGO over time and governs shelf-life; HMF confirms the honey hasn't been overheated or stored too long.

UMF™ 5–10+

A natural sweetener to support a healthy lifestyle.

UMF™ 10–20+

A more potent product for everyday health and wellness.

UMF™ 20–25+

Higher potency for additional nutritional support.

Request Spec Sheet
Composition

What's actually in the jar.

Honey is composed mostly of sugars, alongside water, enzymes, minerals, vitamins and bioactive compounds. Mānuka's antibacterial and antioxidant properties come from its concentration of methylglyoxal, interacting with compounds unique to the mānuka myrtle tree.

  • Sugars & Fructose 38%
  • Glucose 30%
  • Water 18%
  • Oligosaccharides 10%
  • Proteins 1%
  • Phenolics 0.2%

Wound Care

Mānuka honey is FDA-approved in the United States for wound treatment. A 2025 randomised trial found venous leg ulcers healed in 7 weeks with topical mānuka honey, versus 14 weeks with a standard antimicrobial dressing.

Oral Health

In a controlled trial across four mouthwash types, mānuka honey outperformed 0.2% chlorhexidine and two essential oils at reducing Streptococcus mutans and Lactobacillus acidophilus.

Coughs & Colds

A BMJ Evidence-Based Medicine meta-analysis found honey effective for symptomatic relief of upper respiratory tract infections. Separately, in vitro testing showed mānuka honey specifically had potent anti-influenza activity.

Gut Health

A pilot study using mānuka honey to treat Gastro-oesophageal reflux disease (GERD) reported a significant improvement in symptoms versus placebo. Other work explores its prebiotic potential for the gut microbiome.

Antioxidant Activity

Mānuka honey's phenolic compounds and flavonoids (quercetin, luteolin, kaempferol, apigenin) are linked to its antioxidant, antimicrobial and anti-inflammatory activity. An animal study found it reduced oxidative damage in rats.

How to read this section

Research is only as strong as its evidence tier. In vitro work isolates cells in a lab and is useful for identifying mechanisms, but doesn't always translate to the same effect in a whole person. Animal studies allow more complex biological control but still can't be assumed to transfer directly to humans. Clinical trials — especially larger, controlled ones — carry the most weight. This summary reflects the current published literature and is provided for informational purposes; it is not medical advice, and findings (particularly the early-stage cancer research above) should not be read as treatment claims. Anyone considering mānuka honey for a specific health condition should speak with a healthcare provider.

Everyday Use

Separate from the research: how people actually eat it.

Distinct from the clinical evidence above, this is simply how mānuka honey fits into a daily routine. Consume it like any other bioactive food, and avoid high heat where possible to preserve its natural properties.

01

By the Spoonful

The simplest way to take it — straight, once or twice a day, as part of a normal routine.

02

In a Beverage

Stirred into warm (not boiling) tea, coffee, or blended into a smoothie.

03

As a Topping or Drizzle

Over yoghurt, porridge, toast — anywhere a natural sweetener would normally go.

Simple, honestly-sourced spreads with no shortcuts taken on ingredients or process.

Chocolate

Naturally sweetened chocolate pieces, part of the wider wellness pantry alongside the honey.

Buying Guide

What to look for before you buy.

  • A UMF™ rating on the label

    It's the only independently verified way to know the strength — and the honesty — of what's inside the jar.

  • Confirmation it's monofloral

    Genuine mānuka honey isn't a blend. UMF certification confirms single-source origin, not a mixed floral honey.

  • New Zealand origin, stated plainly

    Mānuka only grows here. Any jar without a clear NZ origin claim deserves a second look.

  • A higher number for a reason

    The higher the UMF rating, the more MGO present — match the grade to what you actually need it for.

Not All Honey Is Honest

"Mānuka honey" isn't always mānuka honey.

Mānuka honey is widely sold online and in health stores — but not every jar is telling the truth. Without independent testing, a label is just a claim. The UMF™ Four Factor test exists to verify it, batch by batch.
