Are Peptides Legal in New Zealand?
New Zealand classifies most therapeutic peptides as prescription medicines. In December 2025, Medsafe classified 10 groups of peptides as prescription medicines (Schedule 4 equivalent), including MOTS-C. This makes it illegal to sell these peptides for therapeutic purposes without a prescription. Peptides imported without a prescription are being seized and destroyed at the border. Medsafe has warned of significant health risks from unregulated synthetic peptide use, including contamination, incorrect dosing, and unknown long-term effects. Research use of peptides that do not make therapeutic claims exists in a grey area but is increasingly scrutinized.
