Is Phenibut legal in New Zealand?

Confirmed against a primary sourceVerified July 14, 2026
Legal status
Phenibut is classified as a prescription medicine under the Medicines Act 1981 by the Medicines Classification notice gazetted in 2018 (NZ Gazette 2018-go4068); Medsafe's committee found it did not meet the harm threshold for a Misuse of Drugs Act 1975 controlled drug, so phenibut is regulated as a medicine and is not named as a scheduled controlled drug (mechanism: medicines classification, gabapentinoid/nootropic-class approach).
Consequences if caught
Selling or supplying phenibut when it is not a lawfully prescribed medicine breaches the Medicines Act; because it is not a Misuse of Drugs Act controlled drug there is no drug-possession offence, but unauthorised sale of an unapproved/prescription medicine is an offence.
If prescribed or medical
Phenibut is available only on a doctor's prescription as a prescription medicine, consistent with Medsafe's treatment of the gabapentinoid class.
Documentation
Lawful supply requires a prescription, so over-the-counter 'supplement' sale is not permitted and personal importation is constrained by prescription-medicine rules; individual purchase routes are left to confirmation.
