Topic: "Should 1080 poison be used for pest control in New Zealand?"
The 1080 Debate
1080 (sodium fluoroacetate) is the most widely used toxin for pest control in Aotearoa. It's used to kill possums, rats, and stoats to protect native species. But it's also controversial.
Your Task: Prepare arguments for a class debate on this important environmental issue.
Background Facts | Ngā Meka Tīmatanga
| Fact | Details |
|---|---|
| What is 1080? | Sodium fluoroacetate — a poison that occurs naturally in some Australian plants. Used in NZ since 1954. |
| How is it used? | Dropped from aircraft in bait form, or placed in bait stations on the ground. |
| Amount used | Approximately 80% of all aerial pest control in NZ uses 1080. |
| Target pests | Possums, rats, stoats — which kill native birds and eat native plants. |
| Breakdown | Breaks down in water and soil. No long-term environmental accumulation. |
✅ Arguments FOR Using 1080
1. Protects Native Species
DOC studies show kiwi survival rates increase from 5% to 50-70% in areas with 1080 drops. Native bird populations (kōkako, kākā, kererū) have recovered in treated areas.
2. Most Effective Tool Available
Can treat large, remote areas that are impossible to reach by trapping. 1080 can reduce possum populations by 90%+ compared to 20-40% with trapping alone.
3. Supported by Scientific Research
The Parliamentary Commissioner for the Environment (2011, 2013) concluded 1080 is the best tool currently available. Supported by DOC, regional councils, and most scientists.
4. Breaks Down Naturally
1080 biodegrades in the environment. No accumulation in soil, water, or food chains. Most breakdown occurs within days to weeks.
5. Cost-Effective
Aerial 1080 costs about $15-25 per hectare. Trapping can cost $300+ per hectare. Critical when treating millions of hectares of conservation land.
❌ Arguments AGAINST Using 1080
1. Kills Non-Target Species
Some native birds (weka, kea, tomtits) have been killed by 1080. Dogs are highly susceptible and can die from eating poisoned carcasses. Some deer hunters oppose it.
2. Ethical Concerns
1080 causes suffering before death. Animals can take hours to die. Some consider this inhumane compared to quick-kill traps.
3. Questions About Effectiveness
Pest populations can recover quickly after 1080 drops ("boom and bust"). Some argue money would be better spent on sustained trapping programs.
4. Concerns About Waterways
Though studies show 1080 breaks down in water, some communities are concerned about contamination of drinking water sources.
5. Māori Perspectives
Some iwi oppose dropping poison in sacred forests. Concerns about mauri (life force) of the ngahere and food gathering areas. However, other iwi support 1080 for protecting taonga species.

Post-Debate Reflection
After the debate, answer honestly:
1. Did your opinion change during the debate? Why/why not?
2. What was the strongest argument from the other side?

📋 Teacher Planning Snapshot
Ngā Whāinga Ako — Learning Intentions
Students will engage with this resource to build understanding of Aotearoa New Zealand's ecosystems, biodiversity, and the role of kaitiakitanga in environmental stewardship.
Ngā Paearu Angitū — Success Criteria
- ✅ Students can explain key concepts from this resource using their own words.
- ✅ Students can connect the content to real-world environmental contexts in Aotearoa.
Differentiation & Inclusion
Scaffold support: Provide sentence starters, word banks, or graphic organisers to scaffold access for students who need it. Offer entry-level and extension tasks to address a range of readiness levels.
ELL / ESOL: Pre-teach key vocabulary and provide bilingual glossaries where available. Allow students to respond in their home language first.
Inclusion: Use accessible formats. Neurodiverse learners benefit from chunked instructions and choice in how they demonstrate understanding.
Prior knowledge: Best used after the relevant lesson sequence. No specialist prior knowledge required for entry-level engagement.
