How to Notify Police You Are Growing Hemp at Home (NZ 2025 Regulation Change)

The New Rules for Home Hemp Growing in New Zealand

Recent amendments to the Misuse of Drugs Regulations have changed the rules around growing low-THC hemp in New Zealand, allowing individuals to cultivate approved low-THC hemp varieties without a commercial licence under certain conditions. While you are not required to hold a licence, it is strongly recommended that you proactively notify your local Police to avoid any misunderstanding about your plants.

This template gives you a simple, clear letter you can send or hand-deliver to your local police station before you start growing. The notification lasts for 12 months.

I am writing to inform you that I intend to grow low-THC industrial hemp at my residential property, as permitted under the recent amendments to the Misuse of Drugs Regulations in New Zealand.

I am providing this notification voluntarily and in good faith so that you are aware of my plants should any query arise.

What to Do With This Letter

  • Print two copies — one to hand in, one to keep for yourself.
  • Visit or post it to your local police station before you plant.
  • Ask for a receipt or acknowledgement — even an email reply confirming they received it is useful.
  • Keep your seed packaging and any documentation showing the variety is low-THC.
  • If police have questions, stay calm and refer them to the Misuse of Drugs (Hemp) Regulations amendment.

Frequently Asked Questions

 

How many plants can I grow?

Check the current regulations for any plant number limits that apply to home growers. The rules may specify a maximum number of plants for personal cultivation at this stage they do not.

Can I sell what I grow?

Home growing under the amended regulations is generally for personal use only. Commercial sale of hemp products requires a separate license although it appears non licensed growers can sell biomass to licensed cultivators. Always check your obligations before selling with MOH or licensed cultivators.

Where do I get approved seeds?

It is important to source seeds from a reputable supplier who can confirm the variety is a certified low-THC cultivar. Using unknown or unverified seeds could put you at risk.
