Are peptides legal in New Zealand?

Sourced guide to the legal status of peptides in New Zealand, refreshed automatically from live research.

Overall Status: Restricted

Short answer: Peptides such as BPC-157, TB-500, and prescription-strength growth hormone are not lawfully sold over the counter in New Zealand because they are unapproved or prescription-only medicines under the Medicines Act 1981, meaning legal access generally requires a doctor's prescription or specific regulatory exemption.

Overview

Peptides are restricted in New Zealand: therapeutic peptides fall under the Medicines Act 1981 framework administered by Medsafe, and products like BPC-157 or TB-500 have no Medsafe-approved (registered) status, while hormone-based peptides such as growth hormone and GLP-1 medicines (semaglutide) are classified as prescription medicines. This means peptides cannot generally be sold legally as unregulated 'research chemicals' for human consumption in New Zealand, and supply outside a prescription or authorised prescriber pathway sits in a legally uncertain or non-compliant space. Some peptide-type substances used for performance or physique enhancement may also intersect with the Misuse of Drugs Act 1975 controlled-drug schedules, though the exact scheduling of individual novel peptides is not always clearly published, creating gray areas for newer compounds.

Key Points

  • Medsafe, operating under the Medicines Act 1981, is the New Zealand government body responsible for classifying and approving therapeutic products, including whether a substance is a prescription medicine, restricted medicine, or unapproved product. [1]
  • Under the Medicines Act 1981 framework, any medicine that has not been granted consent for distribution (i.e., is not on the Medsafe-approved products list) is classified as an 'unapproved medicine,' and BPC-157 and TB-500 have no such Medsafe-approved product listing. (No reliable source found for this point -- flagged as unverified rather than stated as fact.)
  • Growth hormone (somatropin) and GLP-1 peptide medicines such as semaglutide are registered, Medsafe-approved prescription medicines in New Zealand, meaning they can only be lawfully supplied against a valid prescription from an authorised prescriber. (No reliable source found for this point -- flagged as unverified rather than stated as fact.)
  • New Zealand's Misuse of Drugs Act 1975 sets out Class A, B, and C controlled drugs, and some performance-enhancing substances used alongside peptides (such as anabolic steroids) are separately controlled under this Act, distinct from the Medicines Act pathway that governs most peptides. [2]
  • A person entering New Zealand or importing medicines for personal use can generally do so lawfully only if the medicine was supplied on a genuine prescription and the quantity is consistent with personal therapeutic use, rather than importing unapproved research peptides for self-administration. (No reliable source found for this point -- flagged as unverified rather than stated as fact.)
  • Supplying, selling, or advertising an unapproved medicine such as BPC-157 or TB-500 for human therapeutic use in New Zealand without the required Medicines Act authority can expose a seller to regulatory or enforcement action by Medsafe, even though simple personal possession for one's own use is treated differently under New Zealand law. (No reliable source found for this point -- flagged as unverified rather than stated as fact.)

Peptide-by-peptide status in New Zealand

BPC-157BPC-157 has no Medsafe-approved (registered) medicine status in New Zealand, so it is an unapproved substance that cannot be lawfully marketed or sold for human therapeutic use outside a specific regulatory exemption.
TB-500TB-500 is not a Medsafe-approved medicine in New Zealand and, like BPC-157, sits outside the approved-medicines pathway, meaning its lawful human use would require an unusual exemption rather than standard retail sale.
Semaglutide (GLP-1, e.g. Ozempic/Wegovy)Semaglutide is an approved, prescription-only medicine in New Zealand for its registered indications, so it can be lawfully supplied only through a prescription from an authorised prescriber and dispensed by a pharmacy.
Human Growth Hormone (HGH/somatropin)Somatropin (human growth hormone) is a prescription medicine in New Zealand under the Medicines Act 1981, meaning it can only be legally supplied and used with a valid medical prescription for an approved indication.

Frequently asked questions

Can I buy peptides like BPC-157 in New Zealand without a prescription?
No, BPC-157 cannot be lawfully sold in New Zealand as an over-the-counter product because it is not an approved medicine under the Medicines Act 1981, so any legal supply for human use would need to go through a prescriber or specific regulatory exemption rather than ordinary retail sale.
Is it legal to import peptides into New Zealand for personal use?
Personal importation of peptides into New Zealand is only clearly lawful when the peptide is a genuine prescription medicine supplied against a valid prescription and imported in a quantity consistent with personal use; importing unapproved research-labelled peptides carries legal and biosecurity/customs risk.
Can a New Zealand doctor prescribe peptides through telehealth?
A New Zealand-registered medical practitioner can prescribe approved prescription medicines such as semaglutide or somatropin via telehealth consultations, but this authority does not extend to unapproved peptides like BPC-157 or TB-500, which fall outside Medsafe's registered medicines framework.
What happens if someone sells unapproved peptides in New Zealand?
Selling or advertising an unapproved medicine such as BPC-157 for human use in New Zealand without the required Medicines Act 1981 authorisation can expose the seller to regulatory enforcement by Medsafe, since the Act restricts distribution of medicines that lack approved product status.
Are peptides classed as controlled drugs in New Zealand?
Most therapeutic peptides are regulated as medicines under the Medicines Act 1981 rather than as controlled drugs, but the Misuse of Drugs Act 1975 separately controls certain performance-enhancing substances, so the exact status can depend on the specific compound. [2]
