Wai Māori: A Taonga

Explore why wai Māori is treasured, how freshwater ecosystems work, and how observations can help us care for waterways. Use scientific evidence and show respect for mātauranga Māori as a distinct knowledge system.

Wai Māori and freshwater ecosystems

Wai Māori means freshwater, including streams, rivers, lakes, wetlands and groundwater. In te ao Māori, wai is a taonga: something treasured and significant, connected with people, place and whakapapa. Kaitiakitanga is the responsibility to care for and protect the natural world. Mauri refers to the life force or living essence of a person, place or thing. Freshwater moves through the water cycle. The Sun warms water, causing evaporation. Water vapour cools and forms droplets through condensation. Precipitation falls from clouds, and water collects in lakes and rivers or moves across and beneath the land. A freshwater ecosystem includes living things—such as plants, fish and insect larvae—and non-living factors such as light, water flow, temperature and oxygen. These parts affect one another. For example, water temperature can influence which organisms survive. Pollution can damage habitats and reduce oxygen, harming aquatic life. Healthy wai supports hauora, or wellbeing. It can provide drinking water, food, recreation, learning and cultural connection. Scientific investigations and mātauranga Māori can both contribute to caring for wai. They have distinct foundations and should be engaged with respectfully.

A. Choose the best answer

Select one option for each question.

1.Which description best fits wai Māori?

Water in oceans only
Freshwater, including rivers and groundwater
Rainwater before it reaches land
Water that has been treated for drinking

2.In this context, what is a taonga?

Something treasured and significant
A type of freshwater insect
A measurement of river speed
A barrier that stops water flowing

3.Which action is an example of kaitiakitanga?

Pouring leftover paint into a stormwater drain
Planting suitable native species beside a stream
Removing every insect from a wetland
Taking more water than a community needs

4.What happens during evaporation in the water cycle?

Water vapour cools into droplets
Liquid water changes into water vapour
Water falls from clouds
Water freezes into ice

5.Which is a non-living factor in a stream ecosystem?

A fish
An aquatic plant
Water temperature
A mayfly nymph

6.A stream contains many invertebrate species that are sensitive to pollution. What is this most likely to suggest?

The water may be in relatively good condition
The stream contains no oxygen
The water must be salty
The stream has no living organisms

7.What does mauri refer to?

The depth of a lake
The life force or living essence
The amount of cloud cover
The speed of a current

8.Which choice is most likely to benefit a stream and its wildlife?

Keeping rubbish out of drains and waterways
Washing detergent into the stream
Removing all plants along the banks
Leaving oil spills to wash away

9.Which is one way healthy freshwater can support hauora?

It can support recreation, food and cultural connection
It removes the need for healthy habitats
It causes pollution in waterways
It benefits only people who live beside rivers

10.Which statement describes a respectful relationship between science and mātauranga Māori?

They are identical in every way
Only one can contribute to caring for waterways
They can both contribute while retaining their distinct foundations
Neither can be used to learn about wai

21.Give one example of how healthy freshwater can contribute to hauora.

22.Describe a fair and safe way to compare observations at two freshwater sites.

E. Interpret the observations

Two teams made observations on the same day. Compare the evidence in the table.

Observation

Site K: forest stream

Site R: town drain

Water clarity

Clear

Cloudy

Temperature

13 °C

21 °C

Invertebrates seen

Many mayfly and stonefly nymphs

A few worms and midge larvae

Other signs

No pollution signs recorded

Litter and an oily sheen

23.Which site appears to have healthier water? Support your choice with at least two observations from the table, then suggest one practical action to improve or protect the other site.
