On May 28 2026, New Zealand modernised its hemp regulatory framework.
NZMCC has worked in coalition for 3 years with representatives the New Zealand Hemp Industries Association (NZHIA), and the Aotearoa Hemp Alliance (AHA), to facilitate this important regulatory change.
Supply to Medicinal Cannabis License Holders
The reforms revoke the Industrial Hemp Regulations 2006 and move low-THC hemp regulation directly under the Misuse of Drugs Regulations 1977, creating a more streamlined and practical framework for industry participants.
Cabinet-approved reforms remove routine licensing requirements for hemp, increase the allowable THC threshold to less than 1 percent, and permit the supply of Hemp plant material (including flowers and leaves) to licensed Medicinal Cannabis producers.
There is a far more practical notification-based system, which significantly reduces barriers for growers and businesses wanting to participate in the sector. Growers must notify Police and the Ministry for Primary Industries (MPI) before planting, and all applicable Food Safety, Agricultural Compounds and Veterinary Medicines (ACVM), and Medicinal Cannabis Scheme requirements continue to apply.
For the absence of doubt, this means in practice that activities with Hemp other than with the stalk and seed (that means roots, leaves, or flower) remain prohibited. This includes any form of extraction from hemp plant material. However, any hemp material (including the leaf and flower) may be supplied to a medicinal cannabis licence holder
There are a number of medicinal cannabis licence holders who are interested in Hemp biomass (leaves and flowers). However, NZMCC are still discussing with the authorities some of the finer requirements of how that can be practically delivered. NZMCC recommends that, before planting any Hemp to be supplied to a licensed Medicinal Cannabis producer, Hemp growers ensure they have an offtake agreement in writing with the License holder. This will protect you and the License holders should Police or MPI inquire.

Hemp Pollen Drift
While pollen control is not explicitly prescribed in regulation, this is a significant issue.
Hemp is wind-pollinated and male plants produce very large quantities of pollen during flowering. Hemp pollen has been reported to be able to travel more than 10km in NZ the right conditions.
Unmanaged pollen can result in seeded flower crops, reduced cannabinoid yield (2-3x reduction potential), contamination of neighbouring hemp crops, compromised seed integrity and genetic purity, loss of seed certification following harvest, and long-term THC compliance risks through contaminated seed progeny (unstable cannabinoid levels including THC).
Pollen drift is a significant challenge and risks include rejected contracts, commercial disputes and potentially legal action for lost revenue between growers. We are asking for responsible pollen management from the entire sector.

The hemp and medicinal cannabis sector are still working through options to mitigate the risks. In the meantime, be aware of the potential impacts and please advise your neighbouring farms of your crop.
