New Zealand Is Using Starlink to Protect Its Wilderness and It’s Starting With Smart Toilets

Satellite-connected toilets could save money, reduce emissions, and help wildlife.

Deep in New Zealand’s wilderness, even going to the loo can be a logistical challenge. Not for hikers, necessarily, but for the rangers tasked with keeping remote facilities running. Checking whether a toilet needs emptying can mean hours of travel, sometimes even by helicopter.

Now, New Zealand has an unusual solution: broadband satellites.

The country’s Department of Conservation (DOC) has launched a pilot project that uses satellite-connected sensors to monitor remote toilets, huts, and wastewater systems. The network, supported by telecommunications company One NZ and SpaceX’s Starlink, could save millions in maintenance costs over time.

But the project has a much bigger ambition: to use that same technology to track invasive predators and protect some of the world’s rarest wildlife.

Toilets that phone home

New Zealand manages around 2,000 public conservation toilets, many scattered across isolated mountain trails and national parks. Keeping them operational isn’t easy.

Traditionally, rangers have relied on scheduled inspections and estimates of how frequently facilities need servicing. Sometimes they arrive to find everything in working order. Other times, problems develop before anyone notices.

The new Connected Conservation programme aims to change that.

The pilot was announced in April this year, and it involved installing more than 50 smart sensors across over 20 remote facilities. The first installations began in early April, targeting difficult-to-reach sites in Mount Aspiring, Fiordland, and Tongariro National Parks.

Sensors can track wastewater levels and facility use, transmitting information remotely so staff can decide when intervention is actually necessary, instead of sending someone to check at fixed intervals.

The potential savings are substantial. DOC estimates that more targeted maintenance on some of its busiest trails could save over NZ$1 million across six years, while avoiding approximately 30 tonnes of carbon dioxide emissions. Much of the benefit would come from fewer unnecessary helicopter flights and vehicle journeys.

“The toilet sensors are just the tip of the iceberg,” said Karl Beckert, DOC’s director of monitoring and insights, in the department’s announcement.

Satellite internet goes into the wilderness

Satellite communications are reaching places that conventional telecommunications infrastructure cannot easily serve; and they’re doing so at increasingly affordable prices.

Fibre broadband delivers fast, reliable internet to homes and businesses, but extending physical fiber optic cables into remote mountain valleys and protected wilderness can be impractical. Mobile networks have similar geographical limitations because their towers require infrastructure and coverage.

According to One NZ, around 40% of New Zealand’s landmass lacks traditional mobile coverage. But Starlink can reach almost any place, no matter how remote, as long as you have their terminal.

Its satellites orbit Earth at relatively low altitudes, forming a network that can transmit information without requiring a nearby mobile tower.

One NZ’s satellite-enabled Internet of Things (IoT) service uses Starlink’s Direct to Cell technology. Compatible devices can communicate through satellites using cellular technology, allowing small amounts of information to travel from remote locations. IoT is the term for ordinary objects equipped with sensors and connectivity, enabling them to collect and exchange data.

The conservation pilot combines One NZ’s satellite network with other connectivity approaches. It doesn’t require every individual sensor to communicate directly with a satellite.

Now, New Zealand is increasingly considering more ambitious projects.

From smart toilets to saving wildlife

New Zealand faces enormous conservation challenges.

Its native wildlife evolved for millions of years without many of the mammalian predators found elsewhere. When humans introduced rats, stoats, possums, and other predators, the ecological consequences were devastating.

Today, introduced predators kill an estimated 25 million native birds annually, according to DOC. More than 4,000 unique native species are threatened or at risk of extinction.

The country has committed to an ambitious Predator Free 2050 programme, aiming to eradicate some of its most damaging introduced predators.

That requires an extraordinary amount of monitoring, particularly in remote habitats.

Alongside its toilet sensors, DOC is trialling connected predator traps and wildlife cameras. These devices could report animal encounters remotely, helping conservation teams understand what’s happening without constantly visiting each location.

A trap that reports activity or a camera that alerts researchers to an animal’s presence could allow staff to respond more efficiently. Networks of connected devices could also provide better information about where conservation efforts are needed most.

Reliable connectivity could nonetheless remove one of the practical obstacles to managing isolated conservation areas.

The project’s real significance may be less about bringing the internet into the wilderness than about making it possible to monitor remote places without repeatedly disturbing them. But there’s still a way to go; having some sensors that send information once or several times a day is one thing; streaming or recording large video files is another.

For now, New Zealand is testing that possibility in one of the least glamorous places imaginable: a backcountry toilet.

If the experiment succeeds, its impact could extend far beyond the restroom.
