Our forests are speaking. Are you listening?
Set it. Leave it. Know exactly what's living there. Solar-powered and built to last, HARK runs autonomously in the harshest conditions Aotearoa can throw at it — recording continuously, using AI to detect and identify species, and reporting what it hears live, 24 hours a day.
Some of our forests are falling silent.
And we're barely noticing.
In Aotearoa New Zealand, native bird populations are declining while predator numbers rise — unseen, unmeasured, uncontested.
Most of the land is remote, uninhabited, and extremely hard to reach. Traditional monitoring is expensive, infrequent, and produces only a snapshot.
A 5-minute bird count, once or twice a year, is the best data many conservation teams have. That's not enough to save a species.
"How do we give a voice to forests that are too remote, under-resourced, or too expensive to monitor consistently?"
— The question that started Hark
Built for the bush.
Engineered to last.
3 microphones. Every direction.
Three analog microphones capture the full acoustic scene simultaneously. Direction detection, triangulation, and up to 192kHz for ultrasonic recording — in hardware built for years of unattended field operation.
Google's Perch v2. On a solar panel.
The world's most advanced bird-identification model, running fully offline in the deep bush. 100+ species classified simultaneously in real time, with zero connectivity required.
Deploy once. Forget about it.
LiFePO₄ battery with 10-year lifespan. Charges down to −20°C. Stainless steel enclosure, kea-proof, rat-proof, field-hardened. Set it up, walk away, and trust it will still be listening in a decade.

Deploy once.
Monitor forever.
Deploy
Mount a Hark device in your monitoring area. Solar panel, stainless enclosure, done. It self-configures and connects to the cloud.
Listen
Three microphones can listen continuously at up to 192kHz — capturing birds, bats, insects, and ecosystem soundscapes on whatever schedule you remotely set.
Classify
Perch v2 — Google's world-class audio AI — runs in real time on the edge. Run 100+ species simultaneously with minimal power.
Transmit
4G where available. If not, Hark devices form a mesh network — routing data through the forest, valley by valley, until it reaches the cloud.
Understand
Real-time dashboards show species detections, trends, audio recordings (requestable on demand), and ecosystem health metrics — from anywhere in the world.
Act
Conservation teams receive alerts, spot invasive pests early, verify restoration outcomes, and make faster, better-targeted interventions.
Achieving the impossible.
Running the world's most advanced bird-identification AI on a small solar panel, deep in the New Zealand bush. No mains power. No data centre. Just some cleverly constructed circuit boards, a tonne of low-level optimised firmware — and a healthy dose of Kiwi ingenuity.
Species classified simultaneously in real time
Lines of highly optimised low-level custom firmware & AI code
Max sample rate — capturing birds, bats, insects, and ultrasound
GPS timestamp accuracy via high-spec GNSS + PPS signal
LiFePO₄ battery lifespan, fire safe and charges down to −20°C
FLAC compression possible — lossless audio at a fraction of the size
Built from the ground up.
Multiple custom circuit boards, designed from scratch. Extreme low-level programming to squeeze world-class AI onto hardware that runs on a small solar panel in the deep bush.
Nothing off-the-shelf. No shortcuts. Every component, every circuit, every line of code — built to do more with less, so HARK can run for years without anyone touching it.
Total control.
From anywhere.
A full cloud platform included. No third-party software, no data exports, no waiting. Everything your team needs, live, from your browser.
Listening to the forest.
Standing beside the people who protect it.
"A forest with high mana is one that is healthy, abundant in birdlife, has strong tree growth, and has rich biodiversity. That is what we are working to restore."
In 2025, alongside Air New Zealand and partners, we planted 28,000 native trees to restore biodiversity corridors across Aotearoa.
We work alongside Ngāti Maru iwi, pairing technology with traditional stewardship. The land remembers who cared for it.
Collaborating with the University of Auckland on population density estimation, direction detection, and biodiversity science.
Backed by the New Zealand Department of Conservation and Predator Free 2050 Ltd — the highest validators in NZ conservation.
Always learning.
Always improving.
Continuously retraining to identify more birds and bats unique to Aotearoa
Ultrasonic detection and species ID for native bat populations
Using HARK's three microphones to determine which direction a call came from — active research with a University of Auckland PhD student
When multiple HARK devices hear the same call, calculate exactly where the caller was using time-of-arrival differences
Automatically detect and flag recordings containing human voices — keeping your wildlife data clean and privacy intact
Custom reports that surface population trends, seasonal patterns, and biodiversity changes over time — turning raw detections into conservation insight
