Mangaroa Farms is a laboratory for regenerative living: a charitable organisation on 1,222 hectares, forty minutes north of Te Whanganui-a-Tara / Wellington, with seventeen people working towards ecological resilience, accessible kai and community education.
Farms, forests and communities across Aotearoa are being asked to adapt to a climate that's becoming less predictable, while rising costs make that adaptation harder.
At Mangaroa Farms, we keep coming back to one answer: stay anchored in care for the land and each other.
This report shares our work between 1 April 2025 and 31 March 2026. What we tried, what we learned, and what remains unresolved. We welcome all voices as we work out how to best show up for this place, now and going forward.

Mangaroa Farms is committed to honouring Te Tiriti o Waitangi.
Ko Remutaka e tū ake nei, tēnei te mihi nunui
Ko Mangaroa te awa e rere ana nei, he mihi māioha
Ko te whenua Mangaroa e takoto nei, he mihi ana
Ko Waiwhetū rāua ko Ōrongomai ngā marae, Tēnā kōrua
Tēnei te mihi aroha ki ngā mana whenua o te rohe
Te Ātiawa rātou ko Taranaki Whānui ki Te Upoko o Te Ika
Tēnā koutou, Tēnā koutou, Tēnā koutou katoa!
We acknowledge the Remutaka range that shelters us, Te Awa o Mangaroa flowing between these hills, and Waiwhetū and Ōrongomai, the marae of this rohe. We pay respect to those who walked here before us.
There is much to learn from mana whenua: the mātauranga of long-standing presence and deep historical relationship with this cherished whenua. We walk alongside Te Ātiawa and Taranaki Whānui, on a journey of healing, restoration and reconnection.
Ka ora te whenua, ka ora te tangata: when the land is well, we are well.
Sharing the work is the fastest way we've found to make food more accessible. We can't compete with supermarkets on price, so we're welcoming participation through pick-your-own and growing co-ops.
Pick your own
48
families came to pick their own kai.
+ How it worksPick your own
×Our community gets quality veggies for a lower cost when they do the picking. Twenty bucks, fill a crate, take it home.
48 families came along, half of them new. Seventeen came back again. We're growing PYO into a full season, October 2026 to April 2027.
Garden soil
0.4 → 0.29 mg/kg
spray residue clearing out of our soil
+ What we feed itGarden soil
×Growing intensively puts pressure on soil, so half the job is making sure the ground improves rather than depletes.
We feed the biology, not the plant: compost extracts, microbial drenches, cover crops, mulch, minimal disturbance. Organic certification begins with our microgreens in FY27. The paperwork is catching up with the practice.
Regenerative agriculture
333
cattle on our pastures, almost double a year ago
+ The paddock shiftRegenerative agriculture
×528 sheep and 333 cattle across 576 hectares of pasture and grazed hill country, born here and living their whole lives on pasture that grows without irrigation or imported feed. No routine or prophylactic antibiotics, and no GMOs or synthetic hormones.
The year's big shift happened in the paddocks: the herd moved from sheep-dominant to almost double the cattle. That shift is what makes virtual fencing work: Halter's collars guide 220 of the cattle by GPS, up from 100 last year, moving stock off wet ground and out of waterways without a physical fence. This allows us to prioritise soil and animal health while maintaining labour efficiency.
Permaculture orchard
90
fruit & nut varieties through their first full season
+ First seasonPermaculture orchard
×Five 100-metre rows of trees, continually testing what grows best in this valley and its changing climate. The first fruits have arrived, and this area has the highest worm count in the valley. Brought to life with gifted plants and volunteer labour.
Community donations
Weekly
kai donations to Ōrongomai Marae, our local marae, across the year
+ Where it wentCommunity donations
×Across the year we weighed every bit of kai that left the shop as a gift rather than a sale, 263.21 kg in all. Ōrongomai Marae took our greens almost every week of the high season, and returned it by sharing hāngī with our visitors at Harvest Festival. Another 35 kg of venison from our own hunting control went to the Upper Hutt Foodbank.
Our food basket
101
Farm Shop suppliers across Aotearoa
+ The affordability gapOur food basket
×Over half our suppliers come from the Wellington region, making the Farm Shop / Kete Kai a key point in the local food network. The problem is accessibility for our own produce and meat. Closing the gap between quality and affordability is our core focus for FY27.
Bioregional economy
2,345
dozen eggs, laid and sold in the valley
+ Meet the neighboursBioregional economy
×Jason and Sarah's hens are up Blue Mountains Road. Their business No Boundaries eggs was our biggest external vendor of the year. Nine of our 101 suppliers come from Mangaroa and Whitemans Valley, a number we'd love to grow.
24/7 food at the shop
$5,861
of trust-based kai in the honesty fridge.
+ How trust works24/7 food at the shop
×We've got honest neighbours. The fridge runs on an unstaffed honesty system, holding eggs and veges. People get what they need, leaving cash or making a bank transfer.
Next for Community and Food
In our next cycle we'll be running a full pick-your-own season, hands-on education workshops, and more bulk meat offerings.
We measured the whole farm for the first time, and found that these forests can't yet regenerate themselves. Birdsong is thin due to invasive species, so we're focusing our work there.

Health of Te Awa o Mangaroa
Upper-mid
regional water-quality range for te Awa o Mangaroa
+ What keeps it cleanRiver health
×The river is our namesake, and a clear measure of our success. Stock stay out of the waterways and the banks get planted. In FY27 we plan to pair Halter's virtual fencing technology (GPS collars that steer stock without physical fencing) alongside riparian planting.
Land cover
40%
land cover in old-growth native forest
+ How the land is usedLand cover
×Of our 1,222 hectares, 40% is native forest, 30% in pine plantation, 20% in pasture. The last tenth is peat, waterways, new plantings and houses. Steep ground grows trees, easy ground grows food. The shape of the land decides the use. The pines came with the land, and what succeeds them is a long-term question we're working through.
Microclimate sensing
9
sensor types active across 2 weather stations
+ What sensors tell usMicroclimate sensing
×Weather stations in the garden and under the native forest now measure 9 different sensor vectors. They show us when to sow and where stock can go without damaging soil. It also shows what trees are worth on a farm, which is how we decide where to plant next.
Biomass baseline
1,500 t
of carbon per hectare in the peat swamp, an early estimate
+ Early dataBiomass baseline
×Our first biomass baseline, trialled with Silvi, covers the back bush, our regenerating forest and the pines. Young forest is gaining, the old bush slightly declining. Early data, still being validated.
Trees planted
8,546
natives planted across 3.3 ha
+ DetailsTrees planted
×We've been planting waterways and strategic areas on the farm. 2,900 trees planted by our volunteer community, 2,550 through trials with Groundtruth, 2,091 alongside Greater Wellington, and 1,005 by the team.
Peat swamp
15 ha
of ancient peat swamp scoped for restoration from 2026/27
+ The restoration planPeat swamp
×Fifteen hectares of ancient peat swamp, holding more carbon per hectare than any other ground on this farm. We're planning to take it out of grazing in FY27 to restore its health.
Technique trials
0
sprays in our tree-establishment trials
+ What we’re learningTechnique trials
×Alongside Groundtruth, we've been testing methods for tree survivability. Guards versus no guards, grazing management, cost per surviving tree. We're after the most effective way to establish natives without spray. What we learn gets shared with Aotearoa's wider reforestation ecosystem.
What we plant next
16,000+
plants going in next year
+ The species mixWhat we plant next
×Multipurpose timber woodlots, species chosen to feed native birds and bees, and wide-spaced silvopastoral plantings that give shelter, shade, fodder and timber on the same ground. Supported by an on-farm nursery, in partnership with Heritage Nursery.
WHY PREDATOR MANAGEMENT IS CRUCIAL
The bush can't regenerate while browsers and predators are in it. Remove those, and everything else starts to return: seedlings, understorey, and birds.
…and around again. It compounds, and sensors are now watching.
Trapping
242
predators removed across 78 monitored traps
+ How trapping worksTrapping
×Possums, rats and stoats prey on native birds and their eggs. Every catch is logged in Trap NZ's platform for community visibility. When we remove the predators, birds begin to thrive, and restore balance to the ecosystem.
Hunting
95
deer and goats hunted, of an estimated 190
+ Why browsers matterHunting
×A full-farm thermal scan estimated 190 browsing animals on the property: 150 deer and 40 goats. These browsers are an issue because they eat the seedlings that would replace the canopy as the older trees die. Removing them helps the forest to naturally regenerate itself.
Birdsong
2.73
tūī per count in our regenerating bush, matching bird sanctuary numbers
+ What’s still missingBirdsong
×Tūī now match bird-sanctuary counts, but one strong species doesn't make a dawn chorus, which is why the scorecard still reads under pressure. The gap in birdsong is where the work lies: kākāriki and tītipounamu are still in the bush, surviving rather than thriving.
Take the browsing off and the understorey thickens; thicken the understorey and birds have somewhere to nest.
Kiwi returns
1
kiwi recorded in the Mangaroa catchment, for the first time in a century
+ Who made it happenKiwi returns
×There was a kiwi recorded further up the Mangaroa river catchment, for the first time in over a century. That result belongs to the whole movement, not to us alone. With thanks to Groundtruth, Trap.NZ, Trap and Trigger, Pest Free Upper Hutt, Forest & Bird Upper Hutt, Greater Wellington Regional Council, and all the valley residents who have worked towards this vision.
Next for Ecological Resilience
For the year ahead, we're planting 16,000+ more trees, the peat swamp is coming out of grazing, and involving our local community in predator management efforts.
This year, an acoustic monitor near the valley recorded a kiwi call, the first in over a century.

Events are how people find this place; the learning pathway is why they stay.
Learning pathways / depth over reach
Earth School
130
learners spent 4+ hours here
+ Hours on the landEarth School
×Between Earth School Aotearoa and the schools who visit us, 130 learners spent more than four hours on the farm this year, 15 spent more than fifty hours, and 9 learners spent over two hundred hours.
Hands-on workshops
536
people at 41 hands-on learning sessions
+ Who they were forHands-on workshops
×Forty-one hands-on sessions, from earth building to home herbalism, averaging about thirteen people each. Nearly two thirds ran free or sponsored, and four in five were built for schools and community groups rather than general ticket sales. We hosted three professional learning days for teachers on top of that.
Young people in farming
4
teenagers mentored on-farm
+ Where they went nextYoung people in farming
×Four under-17s worked alongside our farm manager this year: stock work, grazing, animal health, and jobs they had to finish alone.
One has gone on to a farming cadetship, another's building hours for Growing Future Farmers. Farming starts to look like a career worth having, especially for the young women.
Mahi exchange
40
learning residents from 14 countries
+ Life on the farmMahi exchange
×40 learners from fourteen countries lived and worked with us in full immersion, discovering and practising earth-based skills across restoration and food production. They flex our capacity for education: tactile, experiential, a living classroom. 68 volunteers came for planting days, and 5 households joined the Potato Growers Co-op.
“As a parent, I wanted my children to grow up learning from the land, guided by wonder, and surrounded by community. Earth School responds to that desire.”

Gathering in nature
86
events hosted on the farm
+ What happens hereGathering in nature
×Events are how people find this place. A lot of people just come once. Some come back every month. From farm to table dinners to breathwork journeys, technology gatherings and farm tours, these facilities have heard many different kōrero.
Masculine Vitality Experience
70
men through nature wellbeing immersion with BROS Aotearoa
+ Why it mattersMasculine Vitality Experience
×BROS Aotearoa held their first two Masculine Vitality Experiences here, 35 men each, for challenge, connection and nourishment. Men left more connected, to themselves and each other. Mangaroa Farms provided the land and the kai.
The crowd pleaser
Up to 1,500
attendees at our Spring & Harvest Festivals
+ Festival daysThe crowd pleaser
×Our biggest days of the year come in November and March, when we open the gates for a day of farm charm. Up to 1,500 people gathered here each time for garden tours, Mangaroa kai, market stalls, live music, kids activities and more.
Earth Fellows
10
regenerative leaders, backed by $100k in direct grants
+ The cohortEarth Fellows
×This year we hosted our first Earth Fellows cohort, with 10 leaders in food, farming, housing and landcare across Aotearoa. This work strengthens the relational bonds of Aotearoa's regenerative movement: leaders sharing what works, building together, and yes, finding a rare chance to rest along the way. The fellowship has already given rise to further collaboration with Mangaroa Farms.
Staff & community housing
11
households make their home here
+ Who lives hereStaff & community housing
×Eleven households live in Mangaroa Farms housing: six homes provided to staff and contractors, and five rented to the local community, keeping the people who work this land, and the neighbours who love it, close to it.
Gardens of significance
4-star
rating earned by Woodcote Gardens
+ The gardensWoodcote Gardens
×NZ Garden Trust is a nationwide network of quality-assessed gardens of significance throughout the country. Our flagship event space received a 4 star rating for the blend of native and exotic species, as well as a focus on biodiversity and long-term resilience.
Next for Events and Education
In the year ahead we're turning one-off school visits into ongoing relationships, opening more common spaces for people to create with, and readying the farm's homes for more people to live and work here.
Mangaroa Farms is a laboratory for regenerative living.
We're a charitable organisation on 1,222 hectares, forty minutes north of Te Whanganui-a-Tara / Wellington in Aotearoa New Zealand, with seventeen people working towards ecological resilience, accessible kai and community education.
Mangaroa Farms began as a seed in 2018, two years after the first farm block was purchased, when the Monahan family asked how they might live more deeply in service to the land. They gifted the farm into Biome Trust, and it has grown from there.
An honest accounting
Where we're falling short — and how we're responding
Where our results fall short of our aspirations, we're using those gaps to guide the next stage of the work.
And across everything
Te Tiriti o Waitangi
Tangata Tiriti
Mangaroa Farms remains committed to upholding the mana of Te Tiriti o Waitangi, and learning how to embed this in our daily work. We're working towards this by engaging closely with our iwi allies so that Mangaroa Farms supports the uplift of Māori voices, projects and worldviews.
We approach this with humility and a commitment to meaningful action, grateful for the relationships that continue to guide our practice. We acknowledge with gratitude Jan Hania, Papawhakaritorito Trust and Erin Matariki Carr for their ongoing support, and for generously sharing their mātauranga with us.
