Rare large black coral discovered near Fiordland
Written by Black Hot Fire Network Team on January 13, 2026
A large black coral has been discovered in the waters off Fiordland, New Zealand. Researchers believe the coral may be the largest ever found in New Zealand waters and represents a vital breeding stock for the protected species.
The coral measures approximately 4 meters in height and 4.5 meters in width, and is estimated to be between 300 and 400 years old.
Coral Discovery and Size
Marine biologist Professor James Bell of Te Herenga Waka—Victoria University of Wellington described the discovery as the largest he has observed in 25 years of marine biology. Typically, black corals encountered during diving are smaller, usually less than 2 to 3 meters tall. The size of this particular coral makes it a significant find.
Conservation and Protection
The discovery of black coral allows for improved protection of the species. Researchers can inform boaters about areas to avoid anchoring or deploying pots, minimizing potential damage. Researchers from Victoria University of Wellington are collaborating with the Department of Conservation to map the distribution of black coral within the fiords.
Ranger Observations
Department of Conservation senior biodiversity ranger Richard Kinsey, who has worked in Fiordland for nearly 20 years, noted the rarity of observing such a large coral. He described the discovery as a special event.
Coral Characteristics and Legal Status
Despite its name, black coral is white in color; the black coloration comes from its skeleton. The species is protected under the Wildlife Act, making it illegal to deliberately collect or damage it.
Further Research and Reporting
Researchers are requesting reports of any black corals exceeding 4 meters in size. This information will aid in mapping their distribution and determining the prevalence of large coral colonies throughout Fiordland.
