What the label legally means
The words "monofloral mānuka" and "multifloral mānuka" are defined in New Zealand law, not by the brand. The Animal Products Notice for bee products, which came into force on 16 May 2024, sets out five attributes a batch must show in laboratory testing before it can be labelled as mānuka for export.
Four are chemical markers and one is DNA from mānuka pollen. The difference between the two grades comes down almost entirely to one compound, 3-phenyllactic acid.
So "multifloral" is not a warning label. It means the bees also worked other flowers, and the honey still cleared a government threshold. It usually costs less than monofloral for that reason alone.
One honest limit: the Notice is an export instrument, binding operators who process honey for export and the exporters themselves. For honey sold on the domestic shelf, MPI's honey labelling guide says a seller stating a floral type must hold evidence to prove it. In practice most mānuka on an Auckland shelf comes from packers who work to the export standard, but the two rules are not the same rule.
Australia also produces honey from Leptospermum species and sells it under the mānuka name, and the right to use that name has been argued between the two countries' industries. The New Zealand definition above binds New Zealand honey only.
UMF, MGO and the numbers
UMF and MGO are potency numbers, and they sit on top of the government floral grade rather than replacing it. MGO is methylglyoxal measured in mg/kg, printed as a plain number. UMF is the Unique Mānuka Factor, a trademark of the UMF Honey Association — an incorporated society of producers, not a government agency.
The association publishes the thresholds behind each UMF grade, which is the clearest way to line the two systems up.
This table shows the minimum markers the UMF Honey Association lists for each of its published grades.
| UMF grade | MGO (mg/kg) | Leptosperin (mg/kg) |
|---|---|---|
| UMF 5+ | 83 | >100 |
| UMF 10+ | 261 | >150 |
| UMF 15+ | 512 | >200 |
| UMF 20+ | 826 | >200 |
| UMF 25+ | 1197 | >200 |
The association is explicit that MGO and UMF are not equivalent: its four-factor test covers MGO for potency, leptosperin, DHA and HMF, so a UMF number carries more testing behind it than a bare MGO number does. A jar showing only MGO is not thereby fake — it is simply reporting one marker. A jar showing a number with no letters at all, and no floral grade, is telling you nothing you can check.
What a higher number buys you
Higher grades cost more, and the price climbs faster than the number does. Going from UMF 10+ to UMF 20+ roughly triples the MGO on the association's own table, and the shelf price of the higher jar is typically far more than triple in the same store — which is the part the packaging does not spell out.
For a visitor buying honey to eat, to put in tea, or to take home as a gift, the low and mid grades are the sensible purchase. The association's own guidance positions 5+ to 10+ as the everyday choice and reserves the higher grades for people specifically seeking potency. This guide makes no health claims for any grade; the numbers above are chemistry, not a dose.
Where to buy in Auckland
Auckland gives you four realistic places to buy mānuka honey, and they differ more in price and range than in authenticity. Every jar legally sold as mānuka rests on the same testing regime, so the specialist store is not selling you a more genuine product — it is selling you range, packaging and advice.
This table compares the four buying options on what each is actually good for.
| Where | Best for | What you give up |
|---|---|---|
| Supermarket | Everyday grades, lowest fuss | Narrow range of high grades |
| Pharmacy | Mid grades, staff advice | Often dearer than supermarket |
| Specialist store | High grades, gift packs | Prices set for visitors |
| Airport | Buying after security | Least ability to compare |
Buy in the city if you can. The airport's advantage is timing rather than price: honey bought after security screening is not caught by the carry-on liquids and gels limit, so an airside jar can travel in your cabin bag when a supermarket jar cannot.
Spotting an overpriced tourist jar
An overpriced jar usually signals itself through what it leaves off the label rather than what it puts on. The check takes about twenty seconds in the aisle.
- Find the floral grade. If neither "monofloral" nor "multifloral" appears anywhere, you cannot tell which government threshold the honey met.
- Find the number and its system. "UMF 10+" and "MGO 261" are checkable; "Active 15+", "Premium", or a bare "15+" are not defined by MPI or by the UMF association.
- Work out price per 100g and write it down. Jar sizes are chosen to make comparison awkward, and 250g against 500g at different grades is the trap.
- Discount the gift box. Wooden lids, presentation tins and souvenir branding are priced in, and the honey inside is graded exactly like the plain jar.
- Compare the same grade across two shops before you commit, rather than comparing two grades in one shop.
Tourist-facing shops in the central city and at the airport are not doing anything improper by charging more. The premium is for the location and the packaging, and it is entirely avoidable by buying the same grade in a supermarket earlier in your trip.
Getting the jar home
Honey can leave New Zealand freely, but it may not be allowed into your own country. MPI's guidance on taking honey overseas says you can carry honey out in checked or hand luggage, and puts the responsibility on you to check the destination country's customs and quarantine rules first.
Two practical points follow from that page. Honey over 100ml or 100g bought before security screening — at a supermarket, for example — needs to go in checked luggage. And restrictions may be tighter if the container is not commercially packed and unopened, which is a reason to leave the seal alone until you are home.
Before you leave the shop
Check three things on the jar in your hand: the floral grade, the potency number with its system letters, and the price per 100g. If all three are present and the price per 100g is one you have compared somewhere else, you have bought sensibly regardless of which shop you are standing in.
This guide does not cover retail prices, which change constantly and were not verified here, or any medicinal use of honey. For current prices, compare the same grade on two New Zealand supermarket websites before you shop.
