Most people think of New Zealand and picture rolling green hills, hobbit holes, or maybe the jagged peaks of the Remarkables. They aren't thinking about a chain of volcanic peaks poking out of the Pacific a thousand kilometers northeast of Auckland. Honestly, most Kiwis couldn't even point to the Kermadec Islands New Zealand on a map without a bit of sweating.
It's remote.
We’re talking about a subtropical outpost where the nearest neighbor is basically a whale. If you want to go there, you can't just hop on a Jetstar flight. There are no hotels. No gift shops. No Instagram-friendly cafes. It is one of the last truly wild places on Earth, and that’s exactly why it matters so much right now.
The Wild Reality of the Kermadec Islands New Zealand
The Kermadecs are a string of about 15 islands, but calling them "islands" feels a bit generous for some of them. They are more like the jagged teeth of a massive underwater mountain range. Raoul Island is the big one, the only one where humans—mostly Department of Conservation (DOC) volunteers and GNS Science staff—actually hang out. Even then, they’re basically living on a ticking time bomb.
The whole place is volcanic.
Back in 2006, a DOC worker named Mark Kearney was tragically lost when Green Lake on Raoul Island erupted without much warning. It’s a stark reminder that this isn't a tropical paradise from a postcard; it’s a geological powerhouse. The islands sit on the Kermadec Trench, which is one of the deepest places in the ocean. If you dropped Mount Everest into it, you’d still have a couple of kilometers of water above the peak.
The scale is just hard to wrap your head around. Because the islands are so isolated, the evolution there has gone a bit weird. You've got the Kermadec red-crowned parakeet, which managed to survive after being wiped out by cats and rats on the main islands. It’s a success story that happened mostly because humans stayed away.
Why the Ocean Here Is Different
If you dive into the waters surrounding the Kermadec Islands New Zealand, you aren't just seeing a few fish. You are seeing what the ocean looked like before we messed it up. Large predators—sharks, kingfish, groupers—are everywhere. In most parts of the world, seeing a large shark is a "tell your grandkids" moment. In the Kermadecs, it's just Tuesday.

Scientists like Dr. Rochelle Constantine from the University of Auckland have spent years studying the humpback whales that use this area as a massive blue highway. They stop here to rest on their way from Antarctica to the islands of Tonga. It’s a vital pit stop.
But it’s not all pristine vibes.
There has been a massive political tug-of-war over the Kermadec Ocean Sanctuary. Back in 2015, the New Zealand government announced plans to create one of the world's largest fully protected marine reserves here. It sounded great on paper. However, it ran into massive legal hurdles because of Treaty of Waitangi obligations and fishing rights. iwi (Māori tribes) like Ngāti Kuri and Te Ohu Kaimoana pointed out that you can't just legislate away indigenous rights to the sea, even in the name of conservation.
It's a messy, complicated reality. It shows that even in the most remote corners of the globe, history and politics are never far away.
Life on Raoul: It’s Not a Vacation
Imagine being stuck on an island with five other people for six months. Your only link to the world is a satellite connection and the occasional supply ship. You spend your days hacking away at invasive weeds like Mysore thorn or checking seismic monitors.
That is life on Raoul.
The volunteers who go there are a specific breed of tough. They deal with humidity that makes your clothes feel like wet towels and the constant knowledge that the ground beneath them could rumble at any second. There’s no hospital. If you get seriously hurt, you’re waiting days for a ship or a very expensive, very risky helicopter flight.

But the payoff? You get to see the stars without a single watt of light pollution. You see the Kermadec petrels coming home to roost in numbers that feel prehistoric. It’s a raw, unfiltered version of New Zealand that disappeared from the mainland centuries ago.
The Trench and the Deep Unknown
Below the waves, the Kermadec Trench drops down to about 10,000 meters.
We know more about the surface of the moon than we do about the bottom of this trench. Researchers using ROVs (Remotely Operated Vehicles) have found "supergiant" amphipods—basically massive, shrimp-like creatures—that live in the crushing pressure of the deep. These things are 20 times the size of their shallow-water cousins.
It's alien.
Everything about the Kermadec Islands New Zealand challenges our idea of what "nature" is. We usually think of nature as something we can visit, hike through, or photograph. But the Kermadecs don't care if you're there. They exist perfectly fine without us. In fact, they probably exist better without us.
The Conservation Paradox
There is a weird tension in how we treat the Kermadecs. We want to protect them, but to protect them, we have to spend a lot of money and burn a lot of fuel to get there. The "Million Dollar Mouse" project on the Antipodes Islands showed that we can successfuly clear islands of pests, and similar efforts have been crucial in the Kermadecs to keep the bird populations stable.
The biggest threat now isn't rats; it's climate change and plastic.

Even though nobody lives there, the beaches of the Kermadec Islands are often littered with plastic buoys, bottles, and microplastics carried by ocean currents. It’s heartbreaking. You are in one of the most remote spots on the planet, and you’re still picking up a Coca-Cola bottle from three countries away.
How to "See" the Kermadecs Without Going
Since you basically can't go there unless you’re a high-level researcher or a very lucky volunteer, how do you experience it?
- Follow the Deep-Sea Expeditions: NIWA (National Institute of Water and Atmospheric Research) often posts updates when they send research vessels like the Tangaroa north. The footage of the deep-sea vents is incredible.
- The Auckland Museum: They hold significant collections of specimens and stories from the Kermadecs. It’s the closest most of us will get to the volcanic soil of Raoul.
- Support Local Marine Conservation: The debate over the sanctuary is ongoing. Staying informed about how New Zealand balances Māori rights with environmental protection is the best way to be a "digital citizen" of the Kermadecs.
Practical Insights for the Curiously Minded
If you’re genuinely fascinated by the Kermadec Islands New Zealand, don’t look for a travel agent. Look for a career in conservation or marine biology. The Department of Conservation occasionally opens applications for Raoul Island volunteers, but be warned: they look for people with trade skills—think plumbing, radio repair, or botany—rather than just "enthusiastic hikers."
The islands serve as a global barometer. Because they are so far from heavy industry, the data collected there on ocean temperature and acidity is "clean." It tells us the truth about the health of the Pacific.
To truly understand the Kermadecs, you have to accept that some places aren't meant for us. They are meant for the whales, the petrels, and the deep-sea giants. Our job isn't to visit them; it's to make sure they stay exactly as they are—lonely, volatile, and wildly alive.
