Australian Manuka honey and New Zealand mānuka honey share a connection to Leptospermum plants, but their botanical sources and authentication frameworks are not identical. Scientific research has examined Australian Leptospermum honeys, while New Zealand has established specific testing requirements for honey exported under the mānuka name. (journals.plos.org)
For someone choosing a jar, the most useful question is not simply “Which country makes better Manuka honey?” It is:
Where did this honey come from, what does its grade measure, and what evidence supports the claims on this particular product?
This guide separates origin, grading, certification and value so you can compare products fairly—without assuming that the highest number, most expensive jar or most familiar country name automatically makes the decision for you.
Australian vs New Zealand Manuka honey at a glance
Start by treating these as separate questions rather than combining everything into one impression of quality.
| What to compare | What to check on either product |
|---|---|
| Country of origin | Where the honey was produced, not simply where the brand operates |
| Floral source | How the producer describes and supports the honey’s botanical identity |
| MGO grade | The declared methylglyoxal concentration and relevant testing information |
| Certification | The specific scheme claimed and whether the product participates |
| Traceability | Whether the jar’s batch information connects to supporting records |
| Taste and texture | Your experience of the particular honey, rather than assumptions based on origin |
| Value | Comparable grade, net weight, currency and delivery costs |
Use this table as a shopping checklist. A clear answer in one column should not replace the information needed in another.
For example, a prominently displayed MGO number should prompt you to understand that measurement—not stop you from checking the product’s origin or batch details.
1. Botanical origin: related plants, different sources
New Zealand mānuka honey is associated with Leptospermum scoparium. Australian research has examined honey from several Leptospermum species, including L. polygalifolium and L. liversidgei. That botanical distinction is more informative than treating all Manuka-labelled products as identical. (journals.plos.org)
The Australian Manuka Honey Association describes Australian Manuka honey as honey produced by bees from the nectar of Leptospermum plants in Australia. (manukaaustralia.org.au)
A peer-reviewed study published in PLOS ONE examined 80 Australian Leptospermum honey samples. It found substantial variation between samples and a strong relationship between methylglyoxal concentration and measured non-peroxide antibacterial activity. These were laboratory findings about the samples studied—not proof of the quality of every Australian jar or a promise of a health outcome from eating honey. (journals.plos.org)
The practical takeaway is to avoid blanket conclusions. Australian origin does not make a honey an imitation of a New Zealand product, but neither country’s name is sufficient evidence for every claim on a label.
Compare the particular honey and its supporting information, not an assumed national standard of superiority.
2. MGO explains a concentration, not everything about the honey
MGO stands for methylglyoxal. In Manuka grading, the number describes a concentration in milligrams per kilogram of honey. For example, an MGO 500+ label declares at least 500 mg/kg. It does not mean the honey contains 500 grams of MGO or is “500 times better.” (australianhoneycompany.com.au)
Our MGO 500+ Australian Manuka honey provides an example of how this grade is presented on a product page, alongside its jar-size and origin information. (australianhoneycompany.com.au)
MGO is useful when comparing declared concentrations. However, the same number does not establish that two jars have identical floral composition, certification or other characteristics. MPI’s authentication research explicitly concluded that no single attribute assessed in its programme could independently identify New Zealand mānuka honey. (mpi.govt.nz)
For a fair comparison, match the measurement first, then examine the remaining information separately.
For a fuller explanation of the units and label wording, read our guide to what MGO means in Manuka honey.
3. Authentication and certification are not the same as an MGO number
It helps to distinguish a government export-authentication requirement from an industry certification scheme and an individual laboratory measurement.
New Zealand’s MPI authentication framework
New Zealand’s Ministry for Primary Industries requires honey labelled as mānuka for export from New Zealand to be tested by an MPI-recognised laboratory. Its definition combines four chemical attributes and one DNA marker to distinguish mānuka from other honey and classify qualifying samples as monofloral or multifloral. (mpi.govt.nz)
This framework applies to New Zealand mānuka exports. It should not be presented as an Australian certification requirement or confused with a single MGO threshold.
Australian industry certification
AMHA operates a Mark of Authenticity framework with published criteria. Its requirements include Australian production and testing by an independent approved laboratory against the criteria for the relevant mark. (manukaaustralia.org.au)
When comparing products, check whether the particular brand and product claim participation. Do not assume that every Australian Manuka jar carries an AMHA mark simply because it is Australian.
UMF certification
UMF is a certification system for New Zealand mānuka honey. Its operator describes a four-factor assessment involving MGO, leptosperin, DHA and HMF, together with product traceability. It explicitly distinguishes UMF certification from an MGO or NPA measurement alone. (umf.org.nz)
Consequently, an MGO-to-UMF comparison chart does not grant a product UMF certification. Check the certification actually displayed and the scheme behind it.
These frameworks are explained here to help you interpret labels. Their inclusion is not a claim that Australian Honey Company products hold AMHA or UMF certification.
4. Read the origin statement—not just the brand name
The location of a seller or packing facility is not the same question as the origin of the honey.
The Australian Competition and Consumer Commission distinguishes between country-of-origin claims such as “produced in,” “made in” and “packed in.” These expressions have different meanings. A packing statement should not, by itself, be treated as proof that the ingredients originated in that country. (accc.gov.au)
When comparing jars, read the precise wording. Avoid relying solely on a flag, company address or website domain.
A useful question to ask the seller is:
“Can you confirm where the honey was harvested and how the product information supports the origin stated on the label?”
This is especially helpful when a product page talks extensively about the business but says little about the honey itself.
Do not assume an unclear description is necessarily dishonest. Ask for clarification and make your decision from the information supplied.
Our guide to what 100% Australian honey means explains the origin terminology in more detail.
5. Taste: compare the jar, not an assumed national flavour
A country name is not a tasting note. For your own purchase, a simple side-by-side tasting is more useful than deciding in advance which origin you should prefer.
Use small amounts of two clearly identified honeys and keep the comparison conditions similar. Taste them separately before trying them with food.
Consider the aroma, sweetness, texture, flavour and finish. Write down descriptions that genuinely match your experience rather than looking for a particular answer.
For example, ask:
Would I enjoy this honey on its own? Would I prefer it with yoghurt or toast? Is its texture convenient for how I normally use honey?
This is a personal preference exercise, not an authentication test. “I preferred this jar with breakfast” is a useful conclusion. “Every honey from this country is better” goes far beyond what the comparison demonstrates.
Also keep taste separate from grading. Neither a pleasant flavour nor your preferred texture substitutes for the laboratory and traceability information used to support product claims. MPI’s identification framework, for example, relies on specified chemical and DNA attributes rather than a consumer tasting assessment. (mpi.govt.nz)
6. Compare value using equivalent grades and weights
Before deciding which jar offers better value, put the prices on a comparable basis.
Start with the declared grade and net weight. Then check the currency, delivery cost and any promotion. Record missing information rather than assuming the two offers are equivalent.
A useful calculation is:
Price per 100 g = jar price ÷ net weight in grams × 100
The figures below are illustrative, not current Australian Honey Company prices.
| Example | Jar price | Net weight | Price per 100 g |
|---|---|---|---|
| Jar A | A$45 | 250 g | A$18 |
| Jar B | A$75 | 500 g | A$15 |
Jar B costs more to purchase but less per 100 g. That makes it cheaper by weight in this example—not automatically equivalent in grade, certification or flavour.
For multipacks, use the total net weight across all jars. For example, three 250 g jars contain 750 g of honey, so divide the total product price by 750 before multiplying by 100.
It can also be useful to calculate a separate delivered-cost comparison. Keep the two figures clearly labelled so you know whether you are comparing the honey alone or the complete purchase.
Should you choose a higher MGO grade?
Treat grade as one purchasing preference rather than the only objective.
For example, someone comparing higher labelled concentrations can review our MGO 1000+ Australian Manuka honey, which is presented in a 250 g jar. (australianhoneycompany.com.au)
Compare that product with an equivalent grade and weight elsewhere—not with a much lower-grade jar solely because both are described as Manuka.
Our Manuka honey strength-selection guide provides a starting point for exploring the range. Your final choice can then reflect the grade you want, your preferences and your budget.
7. Look for evidence connected to the batch
For purchasing purposes, a useful question is more specific than “Has this honey been tested?”
Ask:
“Does the available test information relate to the batch currently being supplied, and which claims does it support?”
When reviewing a report, look for the sample or product identification, batch reference, laboratory, test date, reported measurements and units. Where the connection is unclear, ask the seller to explain it.
Avoid treating a report for one sample as automatic evidence for every product sold by the same business.
For UMF-labelled products, the scheme’s operator describes using batch and licence-holder information to trace a jar to its quality certificate. This illustrates how traceability can complement a grading number. (umf.org.nz)
Apply the same expectation of clarity to Australian and New Zealand products, while recognising that their documentation may be organised differently.
Also distinguish between a report showing a particular measurement and one establishing broader authenticity. New Zealand’s authentication research found that a combination of attributes was needed; MGO alone was not sufficient to identify mānuka honey within that framework. (mpi.govt.nz)
Common questions about Australian and New Zealand Manuka honey
Is Australian Manuka honey automatically fake because it is not from New Zealand?
No. Australian Leptospermum honey has been scientifically studied, and AMHA publishes criteria for Australian Manuka honey. Neither point authenticates every retail jar: the origin and claims of the individual product still need supporting evidence. (journals.plos.org)
Does the absence of a UMF mark mean a honey is fake?
No. UMF is a particular certification system, not a label automatically carried by every genuine Leptospermum honey. Absence of the mark does not prove fraud, but nor should you assume an uncertified product has passed that scheme’s assessment. Evaluate the origin, grade and evidence actually claimed. (umf.org.nz)
Does monofloral mean a higher MGO number?
Not automatically. MPI’s monofloral and multifloral classifications depend on its specified chemical and DNA criteria. They are not classifications made simply by placing a honey above or below one MGO grade. (mpi.govt.nz)
Which origin should I choose for a gift?
Start with the recipient’s preferences and the information you can confidently explain.
Compare the labelled grade, jar size, packaging actually offered and total price. A clearly presented jar with understandable product information can be a more thoughtful choice than selecting solely by the largest number on the shelf.
The bottom line: choose the evidence, then the jar
Australian and New Zealand Manuka honey should be compared as individual products—not treated as two uniform categories with an automatic winner.
Begin with clear origin, understandable grading and relevant supporting information. Compare equivalent weights and prices, then choose according to your preferences and budget.
When exploring our Australian Manuka honey collection, review the information on each product page and ask for clarification wherever you need more detail.
The strongest purchasing decision is an informed one: understand what the label promises, check what the evidence demonstrates, and compare like with like.
