Protect the oceans
The oceans are in crisis, but together we have the power to save them, and the wildlife that calls them home.
South Pacific seamounts expedition
We’re embarking on an exciting journey to uncover the secrets of the deep. Follow along and find out what’s at stake.
The oceans are in crisis
The oceans cover over 70% of the world’s surface. They provide food, sink carbon and are home to over half of all life on this planet.
But these great, blue expanses are being emptied of life and filled with trash thanks to human activity.
To protect all sea life, we must challenge industrial fisheries and stop destructive practices like seabed mining. By creating ocean sanctuaries, we can let marine wildlife recover and replenish.
But there’s hope. It’s not too late. We can still rebuild our great blue planet, together.
A Global Oceans Treaty
In March 2023, history was made when governments agreed on a Global Oceans Treaty at the United Nations. This agreement puts in place the possibility of worldwide protection through the creation of global ocean sanctuaries.
The goal is to protect 30% of the world’s oceans by 2030. This is what scientists say is needed to avoid the worst of the climate and biodiversity crisis.
Now the structure is in place, the next step is identifying and creating these global ocean sanctuaries.

PETITION: Support the creation of global ocean sanctuaries
From destructive fishing and mining, to climate change – the threats facing our oceans are growing greater by the day. We urgently need a network of ocean sanctuaries across the globe to protect them.

PETITION: Ban bottom trawling on seamounts
Join the call to demand that the NZ Govt bans bottom trawling on seamounts and similar deep sea features, and stop issuing permits for bottom trawling in international waters.

PETITION: Ban bottom trawling in the Hauraki Gulf
Call upon the Minister for Oceans and Fisheries to ban all forms of mobile bottom-contact fishing including bottom trawling, scallop dredging and Danish seining within the Hauraki Gulf Marine Park.
Seabed mining – a new threat to the oceans
Seabed mining, or deep sea mining, is the newest threat that the oceans face. It involves digging up the sea floor to extract valuable metals.
It’s an extremely destructive form of mining that would damage marine ecosystems beyond repair.
But in New Zealand, seabed mining could start in the South Taranaki Bight thanks to the Fast-Track Bill. This would put rare and endangered animals at risk – such as pygmy blue whales, Māui dolphins, Hector’s dolphins and kororā.
With your help, we can stop seabed mining before it starts. Sign our petition today!
Ban bottom trawling
Bottom trawling is a method of fishing that involves dragging heavy weighted nets across the sea floor. It’s highly destructive as it catches and damages everything in its path – including coral, turtles and many juvenile fish.
In New Zealand, bottom trawling is still permitted. In fact, New Zealand is the only country still trawling in the South Pacific high seas.
Greenpeace is campaigning to ban bottom trawling, particularly in key marine areas, like on seamounts and the Hauraki Gulf.

What is bottom trawling, and why is it bad for the environment?
Bottom trawling is a method of fishing that involves dragging heavy, weighted nets across the sea floor to catch fish. It’s a method favoured by commercial fishing companies because it can catch large quantities but it is incredibly damaging to the seafloor and indiscriminate in the way it kills.

Dark oxygen discovered in the deep sea spells trouble for seabed mining industry
Scientists have found a source of ‘dark oxygen’ 4,000 meters below the surface of the Pacific in the target zone for deep sea mining. The discovery could have far-reaching implications for science and the wannabe deep sea mining industry.
