    depends on specifics

    Melatonin bought overseas, such as a US supplement, is an unapproved medicine in New Zealand. Medsafe says you still need a prescription to import unapproved melatonin for personal use. With a prescription, New Zealand's normal rule for prescription medicine applies: bring no more than 3 months' supply, carry a copy of the prescription or a letter from your doctor, keep it in the original containers, and declare it on your arrival card.

    Since June 2025 New Zealand pharmacies can supply some approved melatonin medicines without a prescription: up to 10 days' supply for jet lag and up to 30 days for insomnia. That covers only products approved in New Zealand, not supplements you bring from abroad.
