Week 2 analysis task — after field sampling, comparing chemical tests, bioindicator data, and mātauranga Māori observations to evaluate the strengths and limits of each approach.

Environmental Indicators Comparison
Compare what different types of environmental indicators can and cannot tell us. Science measures one thing; mātauranga Māori reads another. Together, they give a fuller picture of the taiao.
Free comparison framework, premium localisation path
If you want this comparison customised to your local environment — including specific mātauranga Māori indicators from the iwi of your rohe — Te Wānanga can localise it for your context.
- Add locally specific mātauranga Māori indicators for your awa, moana, or ngahere.
- Integrate real chemical testing data from council monitoring stations nearby.
- Save comparison frameworks in My Kete for longitudinal tracking across the unit.
Kaiako planning snapshot
- Use length: 30–45 minutes as a follow-up analysis activity after field data collection.
- Grouping: Individual or pairs. Whole-class debrief to compare findings across groups and sites.
- Prep: Prepare chemical test results in advance if students did not conduct tests themselves. Have a brief summary of local iwi environmental monitoring practices to reference during mātauranga Māori section.
- Differentiation: Entry groups complete the chemical vs biological comparison only; on-level groups add the mātauranga Māori column; extension groups evaluate which indicators should be prioritised in a genuine policy recommendation.
- Neurodiversity support: Provide a one-row worked example before students begin independently. The comparative table structure helps ākonga who prefer systematic frameworks.

Ngā Whāinga Akoranga / Learning Intentions
- We are learning to represent and interpret ecological data from multiple indicator types to draw conclusions about ecosystem health.
- We are learning to evaluate the strengths and limitations of both scientific and mātauranga Māori approaches to environmental monitoring.
- We are learning to make evidence-based recommendations that draw on more than one knowledge system.
Paearu Angitu / Success Criteria
- I can describe what chemical, biological, and mātauranga Māori indicators each reveal about the environment — and what each misses.
- I can explain why using multiple indicator types gives a more complete picture than any single method alone.
- I can use combined evidence to make a specific, reasoned recommendation about my local environment.
Curriculum alignment / Te Marautanga o Aotearoa
This analysis sheet develops students' ability to represent ecological data using tables and evaluate patterns across indicator types — connecting to the NZ Curriculum's Living World strand focus on ecosystem dynamics and environmental change.
Why this matters in Aotearoa
No single indicator tells the whole story. A water pH test tells you something a bioindicator cannot — and a kaumātua who can read the colour and smell of an awa in different seasons, and who knows where kōura used to congregate, holds knowledge that neither can replicate. Real kaitiakitanga uses all available evidence. This comparison sheet is practice for that kind of integrative thinking.
Whakataurite Tohu / Indicator Comparison
For each indicator type, record what it measures, your specific findings, its strengths, and its limitations.
Āhuatanga Matū — Chemical indicators
e.g. pH, dissolved oxygen, nitrates, turbidity
Our findings:
What this tells us / what it misses:
Āhuatanga Koiora — Biological indicators
e.g. macroinvertebrates, algae, indicator species presence/absence
Our findings:
What this tells us / what it misses:
Ngā Tohu o te Taiao — Mātauranga Māori indicators
e.g. seasonal patterns, species behaviour, oral histories of place-based change
What we learned from research or kaumātua:
What this tells us / what it misses:
Whakaaro hōhonu / Synthesis and recommendation
What does the combination of all three indicator types tell you that no single method could alone?
What one action would you recommend for your local environment, based on your combined evidence?
Entry, on-level, and extension pathway
Entry
Complete chemical and biological columns only. Describe one strength and one limitation for each. Write one sentence recommending an action.
On-level
Complete all three columns with specific evidence. Write a paragraph explaining what the combined picture reveals and what action it supports.
Extension
Evaluate which indicator type should be prioritised in a real management decision and justify why. Research whether local iwi or council use any of these methods in active monitoring programmes.
Hononga Marautanga · Curriculum Alignment
Social Sciences — Ecological Sustainability
Level 3–4: investigate local environmental issues; understand that communities have responsibilities to protect the environment for future generations; develop the skills to take informed, responsible action.
Science — Living World / Planet Earth
Level 3–4: observe and describe patterns in the local environment; connect scientific observation to environmental decision-making; understand that human activity affects ecosystems and that this impact can be reduced through careful stewardship.
Aronga Mātauranga Māori
In te ao Māori, the concept of tohu covers any sign from the natural world that carries meaning about ecological conditions. Tohu are not superstition — they are pattern recognition: if this bird appears, conditions are right for this activity; if this plant is flowering early, the season has shifted. Iwi maintained detailed knowledge of which species acted as reliable indicators for which conditions, and that knowledge was the foundation for resource management decisions. This is indicator ecology by another name.
The comparison you are making between scientific, biological, and mātauranga Māori indicators is not just an academic exercise. In Aotearoa, many regional councils now work with iwi to integrate traditional ecological knowledge into their monitoring programmes. Kākahi counts, tuna population surveys, and kōura habitat assessments are increasingly used alongside instrument-based water quality measurements because both types of evidence capture things the other misses. Your comparison today is a small version of that real-world challenge.
