This article focuses on species identification and regulatory context rather than evaluating individual brands. This is to support informed decision-making by:
- Clarifying species differences,
- Summarising current scientific understanding,
- Outline relevant regulatory considerations within the New Zealand market.
If you’ve been shopping for Lion’s Mane in New Zealand, you’ve likely seen products proudly labelled as “NZ Lion’s Mane.” It sounds great—local, fresh, and potent.
However, species identification within the mushroom category can sometimes create confusion. In New Zealand, products marketed under the common name “Lion’s Mane” may refer to a completely different mushroom.
What is Lion’s Mane?
The true Lion’s Mane, the one used in clinical trials for brain health and nerve regeneration, is Hericium erinaceus.
However, Hericium erinaceus cannot legally be grown fresh in New Zealand. (This restriction applies specifically to live cultures and fresh fruiting bodies, not to imported dried extracts or powders.) It is classified as a “new organism” under the Hazardous Substances and New Organisms (HSNO) Act. The reason is that it protects our native ecosystems, so bringing in live cultures of the true species is prohibited.
Instead, New Zealand growers cultivate a native relative called Pekepeke-kiore (Hericium novae-zealandiae), often also misidentified as “Coral Tooth.” While it is a beautiful, edible native fungus, it is not Lion’s Mane.

Comparison: True Lion’s Mane vs. NZ Native (Pekepeke-kiore)
| Feature | True Lion’s Mane (H. erinaceus) | NZ “Lion’s Mane” (H. novae-zealandiae) |
| Scientific Validation | Extensively studied for NGF & brain health. | No clinical trials or proven health claims. |
| Legal Status in NZ | Illegal to grow or sell as fresh fungi. | Legal to grow and sell fresh. |
| Bioactive Compounds | High levels of hericenones and erinacines. | Genetically distinct; lacks the same research. |
| Appearance | Single shaggy “pom-pom” shape. | Branched, coral-like structure. |
Regulatory Considerations
New Zealand’s Fair Trading Act requires businesses to ensure that product descriptions are accurate and not misleading. Clear species identification is therefore, an important aspect of responsible labelling within the mushroom category.
Consumers may wish to look for transparent disclosure of botanical names and supporting documentation when evaluating products.
Making medical or therapeutic claims
Because Lion’s Mane has been studied for neurological support, it is important that research findings are accurately represented and not generalised across different species without supporting evidence.
In addition, New Zealand regulations place boundaries around therapeutic claims for supplements, reinforcing the importance of science-based communication.
- The Science Gap: At present, there are no publicly available human clinical trials demonstrating that Hericium novae-zealandiae produces the neurological effects observed in studies of Hericium erinaceus.
- The Law: New Zealand law places strict limits on therapeutic claims for foods and supplements. Claims suggesting treatment, cure, or prevention of disease require classification as a medicine under the Medicines Act 1981.
At Mycobio, our approach emphasises species authenticity, research alignment, and transparent sourcing.
How to Identify Potential Labeling Issues
To minimise the risk of being misled by unclear species identification in the New Zealand Lion’s Mane market, consider the following red flags:
- “Fresh NZ Grown”: Because Hericium erinaceus is classified as a new organism in New Zealand, fresh locally grown products are typically derived from other Hericium species.
- Missing Latin Names: If the bottle doesn’t clearly state Hericium erinaceus, they may not be clearly disclosing that the product is derived from a different species.
- Wild Claims: If a local grower is promising “brain regeneration” based on “NZ-grown” fungi, ask for the clinical study on that specific NZ species. At present, there are no published clinical studies on this specific New Zealand species.

The Bottom Line
New Zealand’s native fungi are remarkable in their own right. However, clear species identification is essential so consumers can accurately understand what they are purchasing and how it relates to the body of scientific research.
Informed consumers are better positioned to evaluate quality, transparency, and evidence when selecting mushroom products.
Supplier Evaluation Checklist: 5 Questions for Your Supplier
This checklist is intended to help consumers assess species transparency, research alignment, and product documentation when comparing mushroom supplements.
If you are buying from a brand claiming to sell “NZ-Grown Lion’s Mane,” consider asking suppliers the following questions when evaluating mushroom products.. Their responses can help you better assess if the product is really worth the money.
Can you confirm the botanical name of the species you grow?
– The Red Flag: If they say Hericium novae-zealandiae or just “NZ Lion’s Mane,” it is the native Pekepeke-kiore.
– Why this matters: Authentic Lion’s Mane is Hericium erinaceus. If they aren’t growing this specific species, they cannot claim to have the same clinical benefits found in global research.
Do you have clinical human trials for your specific NZ species?
– The Red Flag: They send you links to generic studies on Lion’s Mane (H. erinaceus).
– Why this matters: Relying on research from one species to support claims about another may raise compliance concerns under the Fair Trading Act, which requires marketing representations to be accurate and substantiated.
Is your product a 1:1 powder or a dual-extract?
– The Red Flag: “It’s 100% natural dried mushroom powder.”
– Why this matters: The human body has limited ability to break down the chitin (cell walls) of mushrooms to reach the medicinal compounds. Without dual-extraction (water and alcohol), you are mostly just eating expensive fiber.
Can you provide a Lab Analysis (COA) showing the Beta-Glucan percentage?
– The Red Flag: “We don’t test for that” or “It’s full spectrum so it’s all in there.
– Why this matters: Without beta-glucan testing, it becomes difficult to independently verify potency or compare products on a like-for-like basis.
How is your marketing compliant with the Medicines Act 1981?
– The Red Flag: If they are claiming their NZ-grown product “cures,” “treats,” or “repairs” neurological conditions.
– Why this matters: Making medical or therapeutic claims for a supplement is strictly regulated in NZ. Making medical or therapeutic claims for supplements is tightly regulated in New Zealand. Products that make such claims may fall under the Medicines Act 1981 and require appropriate regulatory approval.
Why this matters to you
Under the Fair Trading Act, businesses must not mislead you about the “nature, characteristics, or suitability” of a product. Relying on research from one species to support claims about another may raise compliance issues under the Fair Trading Act, which requires marketing representations to be accurate and substantiated.
If you feel you’ve been misled by a brand, you have every right to report your concern directly to the [Commerce Commission NZ].
