The Legal Landscape: Seeds, Plants & Laws
2020 Referendum Outcome
In 2020, 50.7% of voters said “no” to legalizing cannabis. So, while half the country was ready to treat cannabis like any other regulated substance, the other half wasn’t — and here we are.
Why Buying Seeds Is a Risky Business
- Recreational seed imports? Illegal, confiscated frequently by Customs.
- Medical growers with licences can legally buy seeds – but that’s a tiny club (around 52 licence holders as of early 2025) and growing is strictly regulated.
- Street-level sale goes on – but quality is hit-and-miss, and law enforcement is watching.
Pro Tip
Vendors ship seeds labeled as “souvenirs” to dodge the law – but it’s a gamble.
“Gandalf the Green Fairy” & What His Case Means
Paul “Gandalf” Smith provided cannabis to sick Kiwis outside the legal system. In early 2025, police tore down his greenhouses, seized plants, and charged him with supply and cultivation – potential 8-year sentence.
Hundreds rallied for him; supporters say he was no criminal mastermind, just a man with a heart. As one protester noted:
“He’s a compassionate, barefoot hippy with a battered truck and a heart of gold.”
This case unmasked the painful gap in our “legal” system – one that forces people to choose between pricey prescriptions or compassionate underground care.
If You’re Considering Seeds: A Step-By-Step
Yes, people still try to import cannabis seeds to New Zealand. But only do so if you’re fully aware of the stakes.
- Find a trusted seed bank. Look for stealth shipping and germination guarantees.
- Use discretion in delivery. PO box? Alias? Unmarked package? Absolutely.
- Time it right. Spring hits in September. Miss it and you risk mold, pests, or a weak plant.
- Stealth grow smart. Pick hardy strains (I recommend autoflowering seeds), use carbon filters, blackout curtains, and stay under the radar.
- Know the risks. Importing or growing—even one plant—could mean legal action.
Best Outdoor Growing Conditions for Cannabis in New Zealand
New Zealand’s temperate maritime climate resembles that of the Mediterranean, making it surprisingly hospitable for cannabis cultivation in the right regions and seasons. But it’s not one-size-fits-all. Coastal humidity, unpredictable autumn rain, and short southern seasons demand careful planning.
Outdoor Growing Snapshot by Region & Season
| Region | Suitability | Climate Notes |
|---|---|---|
| Northland & Bay of Plenty | ✅ Excellent | Long warm season, low frost, strong sun |
| Auckland & Waikato | ✅ Good | Mild temps, high humidity—watch for mold |
| Hawke’s Bay & Gisborne | ✅ Excellent | Warm and dry—perfect for sativa-dominant strains |
| Wellington | ⚠️ Moderate | Cool and windy—choose hardy, compact strains |
| Nelson & Marlborough | ✅ Good | Dry summers, but shorter overall growing window |
| Otago & Canterbury | ❌ Risky | Frost-prone, limited daylight—better for autoflowers |
Growing Season Timeline
| Stage | Timeline (Southern Hemisphere) | Conditions |
|---|---|---|
| Seed Germination | Mid Sep – Early Oct | Start indoors or in greenhouse |
| Vegetative Growth | Oct – Dec | Long daylight, warm temps |
| Flowering | Jan – March | Triggered by shorter days |
| Harvest | Late March – April | Before autumn rains and frosts |
Climate Parameters for Success
| Factor | Ideal Range |
|---|---|
| Day Temp | 22–30 °C (72–86 °F) |
| Night Temp | 15–20 °C (59–68 °F) |
| Humidity (Flowering) | <50% |
| Rainfall (Flowering) | Low, <50 mm/month |
What to Grow, Where – Recommended Strains in NZ
- Sativa-dominant strains: Thrive in warm, dry zones like Hawke’s Bay and Northland.
- Indica or autoflowers: Better for colder zones (Canterbury, Otago) with shorter seasons.
- Mold-resistant hybrids: Must-have for humid regions like Auckland or Waikato.
Pro Tip
Germinate seeds indoors by late September and harvest by April before wet weather rolls in. Avoid flashy grows and pick strains that suit your exact microclimate.
Medical Cannabis: Legality With Caveats
- Prescription products like Sativex and Epidyolex are Medsafe-approved.
- Unapproved cannabis products still dominate the black market; up to two-thirds of patients use underground sources.
- Licensed domestic growers are rising (29 in 2020 → 52 by early 2025), but many focus on export due to changing rules.
- Medicinal cannabis is still not subsidised by Pharmac, making it affordable to only a few.
Why This Matters
- You’re not a criminal – you’re someone seeking well-being or peace of mind.
- The fact that medicinal patients rely on underground providers isn’t shameful – it’s evidence that the system needs reform.
- If you’re careful, informed, and respectful of the law – you can minimise risks and maximise reward.
Looking Ahead
Momentum for change is still there: NZ public support is high, industry is growing, and export rules are easing. But domestic reform is SLOW.
If you’re growing, stay lawful. Plant wisely. Be ready to adapt – but keep your values rooted.
FAQs
No. Import is illegal and customs are actively seizing packages.
No. Only licensed cultivators are allowed to grow legally — not individuals.
They’ll get destroyed, and you may face prosecution — even for a small package.
Yes — studies show up to two-thirds still rely on them due to cost and access.
Early spring — September to October — to avoid mold and maximize growth.
