Stream Health Assessment
Assess the hauora of your local wai. This field sheet combines habitat observation, pollution indicators, bioindicator scoring, and mātauranga Māori tohu — because no single measure tells the full story of a stream's health.
Free field assessment, premium localisation path
Want this adapted to a specific awa or waterway in your rohe — with iwi-relevant tohu and local monitoring context? Te Wānanga can build a localised version for your school's environment.
- Add site-specific indicators for your local awa, moana, or wetland.
- Integrate mātauranga Māori tohu from the iwi of your rohe.
- Save completed assessments in My Kete for longitudinal tracking across the unit.
Kaiako planning snapshot
- Use length: 45–60 minutes at the field site; 15 min for final judgement and reflection back in class. Can also be run as a classroom exercise with provided photographs and data.
- Grouping: Groups of 3–4 for field observation; individual written judgements. Whole-class debrief to compare assessments across different sites or sections of the waterway.
- Prep: Scout the site in advance. Identify safe access points and any hazard zones. Brief students on observation protocols (minimise habitat disturbance). Clipboards and waterproof bags recommended.
- Differentiation: Entry: habitat and pollution sections only; use provided descriptions for the rating scale. On-level: complete all three sections. Extension: compare their assessment with published council or NIWA data for the same waterway.
- Neurodiversity support: Allow verbal field observations recorded by a partner. Provide the rating scale as a laminated reference card. The structured table format helps students who benefit from clear frameworks rather than open-ended observation.
Resources already provided
- Site information section — awa name, location, date, weather
- Habitat observation checklist — 5 indicators with 1–5 rating scale
- Pollution indicators table — 5 indicators with evidence column
- Mātauranga Māori tohu section — native species, seasonal signs, place history
- Holistic health judgement (healthy / improving / at risk) with evidence requirement
All assessment categories are provided. Combine with the Macroinvertebrate Field Guide for bioindicator data and the Water Testing Protocol for chemical data to complete the full Week 2 field set.
Ngā Whāinga Akoranga / Learning Intentions
- We are learning to assess waterway health systematically — combining habitat, pollution, and mātauranga Māori evidence into a reasoned judgement.
- We are learning to read the taiao using ngā tohu alongside scientific indicators, recognising that both contribute to a complete assessment.
- We are learning to make evidence-based environmental judgements and connect observation to specific recommendations for action.
Paearu Angitu / Success Criteria
- I can rate and justify my assessment of stream habitat quality using specific field evidence for each indicator.
- I can identify at least two pollution indicators and explain what each suggests about the source and severity of impact.
- I can make a holistic health judgement (healthy / improving / at risk) supported by evidence from at least two different indicator types.
Curriculum alignment / Te Marautanga o Aotearoa
This field assessment develops students' ability to gather, record, and interpret environmental evidence — connecting to the NZ Curriculum's Living World strand (ecosystems and environmental change), Science capabilities (use evidence), and Social Sciences (people and environment relationships). The mātauranga Māori tohu section directly connects to kaitiakitanga as a principle of the NZ Curriculum.

Why this matters in Aotearoa
Wai ora — healthy water — is not just an ecological concept in te ao Māori. Water is a rangatira, an ancestor, a source of mauri. The health of an awa reflects the health of everything upstream: the soil, the land use, the relationship between people and place. In Aotearoa, over 60% of lowland river length is degraded. Kaitiaki have observed the decline of their awa for generations — sometimes long before scientific monitoring confirmed what they already knew. This assessment sheet is practice for taking that guardianship seriously.

Ngā tohu o te taiao / Mātauranga Māori indicators
Record any tohu — signs from the living world — that indicate something about this wai's health. These may come from traditional knowledge, kaumātua guidance, or careful direct observation.
Native species present (birds, fish, invertebrates, plants):
Mātauranga Māori tohu relevant to this place or season (e.g. kōura presence, kākahi beds, invasive weed species as warning signs):
What do you know about the history of this wai — its traditional name, its significance to local iwi or hapū?
Whakaaro hōhonu / Holistic health judgement
Healthy
Strong habitat, low pollution, good bioindicator mix, positive tohu
Improving
Mixed evidence — some stress but recovery signs present
At risk
Significant pollution or habitat damage; poor bioindicator score
My judgement (circle above) and justification — cite evidence from at least two sections:
One specific action that would most improve the hauora of this wai:
Entry, on-level, and extension pathway
Entry
Complete the habitat and pollution sections only. Make a judgement with one piece of evidence from each completed section.
On-level
Complete all three indicator sections. Justify your holistic judgement with evidence from at least two sections. Propose one specific action.
Extension
Compare your assessment with council or NIWA data for the same waterway. Write a short analysis: how do scientific scores align with or differ from mātauranga Māori tohu?
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 mātauranga Māori, wai (water) holds mauri — a life-force that can be healthy or diminished. Healthy wai supports tuna (eels), kākahi (freshwater mussels), and kōura (freshwater crayfish); water that has lost its mauri is water that has lost those species. Traditional assessment of water health did not require instruments — it required knowledge: who lives here, what should be here, what is missing? That knowledge was held by those responsible for the awa under kaitiakitanga.
The stream health assessment you are completing today draws on both scientific measurement and this older logic. When you record a species count or a chemical reading, ask yourself: what would a kaitiaki who knew this awa for generations say about what you are seeing? Where do your data and their knowledge agree, and where do they diverge? Both sources of understanding matter for good environmental decision-making.
