A seed crop. Grown for food.
Hemp is one of the oldest food and fibre crops there is. It germinates in a week, grows tall and fast, puts down a deep taproot and produces a seed head full of protein, fibre and oil.
- Legal to growSince 28 May 2026, anyone in New Zealand can grow hemp at home without a licence. You let NZ Police and MPI know before you plant, and that's the whole process.
