Mauri Compass · Wānanga
Introducing the Mauri Compass framework for taiao restoration and mahinga kai in Te Riu o Waiapu.
Welcome and Opening
Introductions and setting the kaupapa. Acknowledging the connection to this place — Ko Hikurangi te maunga, Ko Waiapu te awa, Ko Ngāti Porou te iwi.
Framework Overview
Overview of the 3-Kete approach and the 12 attributes. Positioning the Mauri Compass as a tool for internal planning, cultural vitalization, and environmental stewardship — assessing performance through a Te Ao Māori lens.
Te Ao Taiao & Te Wai Māori
Discussing local environmental challenges — sedimentation, pest devastation in the Raukūmara — and reviewing recent eDNA results from the Maraehara River. What the data tells us about catchment health and the species still present.
Break
Break and informal kōrero.
Group Field Activity
Hands-on group activity using the DOC 5-Minute Bird Count tool on mauricompass.one. Break into groups, pick a station around the marae, count what you see and hear. Connecting the terrestrial story to the freshwater story.
Using the Platform
Practical session using mauricompass.vip. Running a live Strengths & Needs Analysis together — group discussion to score attributes using the 1–5 scale. Discussion questions, wall summary, and facilitator notes.
Shared Kai
Shared kai together.
mauricompass.one
Quick demonstrations of the practical field survey tools on mauricompass.one — Tuna Health Survey, Water Quality, and SHMAK (the school already has a kit). Showing how these connect to the eDNA findings.
Weaving the Compass Forward
How to weave the Mauri Compass into the 'Kia ora ai te whānau' kaupapa. Discussing how the tool supports community-led restoration and future monitoring across the Waiapu catchment.
Closing
Final questions, reflections, and closing the wānanga.
We look at three areas of our world — our people and culture, our freshwater, and our natural environment. Each area has four things we score from 1 to 5.
People, Culture & Governance
Freshwater Health & Taonga Species
Natural Environment & Catchment

Māori population in catchment
Pest devastation — deer, possums, and goats — has severely impacted 200,000 hectares of shared land over 20 years. Forest clearance from 1890–1930 for pastoralism stripped the catchment of its natural protection.
Current cover: Exotic forest 26%, pasture 37%, native 21%
Geology: Crushed mudstones — "rocks like Weet-Bix"
Despite degradation, eDNA confirms native freshwater species are still present — taonga species that signal catchment health worth protecting and restoring. The Ruma Initiative partnership with DOC has employed local kākahi in pest control.
Longfin eel, inanga, torrentfish still detected
Ruma Initiative: hapū + DOC partnership active
Community engagement and local employment growing
Drag to look around — these 360° photos let you stand at the marae and at the replanting site before the mahi begins.
Mauri Compass Biosphere — where the wānanga was held
This is the site before replanting begins — have a look around
Same site, different view — shows the full scope of the area
These 360° photos are our 'before' shots. As the replanting grows, we'll retake them from the same spots — 1 year, 3 years, 5 years — so everyone can see the progress.
Environmental DNA sampling confirms species presence through DNA traces in water samples. The Maraehara is degraded but not dead — there are taonga species to protect.
The river is under pressure but still has life — there’s something to work with
The speckled longfin eel (Anguilla reinhardtii) is an Australian species not native to New Zealand. Its detection (987 reads — the highest count) may represent a Wilderlab database misidentification, possibly matching closely related NZ eel DNA. This should be discussed with Wilderlab and flagged for review.
13 longfin eels measured at Te Korowai o Waikākā. Range: 24cm – 80cm. Average: 52.2cm.

Total Phosphorus — worst 25% and very likely degrading
Ammoniacal Nitrogen — worst 25% and very likely degrading
Total Nitrogen low — best 25% nationally
Nitrate Band A — good for aquatic toxicity
Nitrogen is not the primary driver of degradation here
The story the data tells: Sediment and phosphorus are the primary concerns — consistent with the massive erosion in the Waiapu catchment and cattle access to waterways confirmed by eDNA. Fencing, riparian planting, and erosion control are the priority interventions.
Field survey tools on mauricompass.one selected for their direct relevance to the 2024 eDNA findings and Waiapu catchment context.
We’ll go outside in groups, stand quietly for 5 minutes, and count every bird we see or hear. It’s easy and fun — all on your phone.

Baseline surveys before the replanting project begins
School SHMAK kit — stream habitat, water quality, invertebrate assessment. Results to be entered after the field session.
Awaiting field data
DOC 5MBC protocol — 3 stations around Hinepare Marae. Diversity indices and native/exotic ratio.
Awaiting field data
Freshwater eel survey — CPUE, condition, lengths. Builds on the Oct 2024 baseline (13 longfin, avg 52.2cm).
Awaiting field data
Trap line assessment — species, catch rates, trap condition. Critical for the replanting project — protecting new growth from browse.
Awaiting field data
Why baseline matters: These four surveys establish the pre-planting condition of the site. As the replanting project progresses, repeating these surveys at regular intervals will show measurable change — more birds, healthier tuna, cleaner water, fewer predators.
Photos from the wānanga will be added here
Group activities, field work, and key moments from the day
Here’s our plan — what we can start today, what we’ll do in the next few months, and how we’ll keep tracking progress as the replanting grows.
Can begin today with what we have
SHMAK water quality testing at Maraehara
Driver: E. coli Band D, cattle DNA detected
5-Minute Bird Count baseline at Hinepare Marae
Driver: No terrestrial baseline exists yet
Tuna Health Survey at Te Korowai o Waikākā
Driver: 13 longfin eels measured Oct 2024 — track population
Predator monitoring near replanting sites
Driver: Raukūmara pest devastation — protect new growth
Aligned with the replanting project timeline
Stock exclusion / fencing assessment for Maraehara tributaries
Driver: Cattle DNA in eDNA + E. coli Band D
Riparian planting plan for priority reaches

Tracking change as the replanting establishes
Seasonal SHMAK + Bird Count cycle (quarterly)
Track seasonal variation and year-on-year trends
Annual eDNA sampling — stream + soil
Stream for aquatic health, soil for predator presence and terrestrial biodiversity
Annual Mauri Compass scoring review (wānanga)
Community-led assessment using mauricompass.vip — track all 12 attributes
Compare Poroporo vs Maraehara trajectories over time
SI baseline shows Poroporo TICI 97–100 vs Maraehara 96.35 — track convergence
Predator catch rate trends
Declining catch rates = success. Compare with bird count diversity indices
Photo point monitoring at replanting sites
Fixed photo points — visual record of canopy establishment over years
Every action in this plan connects to the replanting project. Fencing keeps cattle out so seedlings survive. Predator control protects the birds that disperse seeds. SHMAK and eDNA track whether the water is getting cleaner as riparian cover establishes. Bird counts show whether the forest is coming back to life. The Mauri Compass ties it all together — a holistic view of progress through a Te Ao Māori lens.

Voices from the whānau after the wānanga.
"Iron sharpens iron. The Mauri Compass was put to the test today by Te Riu o Waiapu. Patrick Tangaere brought his tauira from kura, teaching tomorrow's scientists today. Taiao expert Graeme Atkins rode his horse across the Waiapu from Tikapa, saving the taiao and fuel along the way. For Te Riu o Waiapu, we calibrated baseline monitoring with our end to end suite of riparian, inanga, eDNA, tuna, SHMAK, predator control, and birdsong to produce irrefutable proof that biodiversity is indeed good for the taiao and its people. Was awesome thanks."

"An absolutely fabulous day with the whānau enjoying more mātauranga, tools and tips so generously shared by you Ian Ruru. Kāre e mutu ngā mihi ki a koe and can't wait to keep building that observations base to help track our progress. Blessed also to have Graeme Atkins with us too to share his mōhiotanga, sharp senses and connection to the taiao!"
