Fiordland is one of the planet's great wilderness areas and an area largely untouched by humans. The area’s recognition from UNESCO ensures the ongoing opportunity for locals and visitors to discover, explore and admire.

Unlike anything else

Fiordland National Park was officially constituted in 1952 and became a UNESCO World Heritage site in 1986. Today, the park is part of Te Wahipounamu South West New Zealand/The place of Greenstone which incorporates Aoraki/Mt Cook, Fiordland, Mt Aspiring and Westland National Parks. One of only three World Heritage sites in New Zealand, Te Wahipounamu is described as an area of 'superlative natural phenomena' and 'outstanding examples of the earth's evolutionary history'.

But Fiordland had a long and active past before humans were ever able to lay eyes upon it. 

A land of uplift and ice ages

The ongoing collision between the Indo-Australian and the Pacific Continental plates is evident by the sight of the mighty Ka Tiritiri-o-te-Moana/Southern Alps. Like the backbone of the South Island, this mountain range runs from top to bottom, reaching 4,000 metres (2.5 miles) at its highest point. Fourteen fiords carve deep indentations into the dense Fiordland coastline. 

The towering peaks we see today were once compacted layers of sediment found on the seafloor. Periods of uplift which occurred hundreds of millions of years ago lifted the seafloor right out of the water, only to have it sink millennia later during a time of submergence. 

Around 100 million years ago, the slow and steady work of the glaciers began to shape a new landscape. As the glaciers carved their way towards the sea, they gouged out the lakes and steep fiords Fiordland is now famous for. Mountain sides scarred by glacial striation, hanging valleys and vast fiords are the tell-tale signs of this powerful glaciation period. What was left behind is a majestic landscape and one of only four places on the planet where fiords are found.

Ata Whenua
To Māori, Fiordland is known as Ata Whenua or Shadowland. A place of towering peaks and plunging valleys and a place where light and shadow create beauty and intrigue.

Few Māori were permanent residents of the region, but seasonal food-gathering camps were linked by well-worn trails. Takiwai, a translucent greenstone or New Zealand jade, was sought from Anita Bay and elsewhere near the mouth of Milford Sound.

A LINK TO THE PAST

As the best intact representation of the flora and fauna of Gondwanaland, Te Wahipounamu South West New Zealand is recognised as being of ‘global significance’. New Zealand separated from Gondwana long before the appearance of marsupials and mammals. Its long isolation is the reason New Zealand has a wide diversity of birdlife, many of which are flightless or have limited flight.

Before the introduction of predatory pests like deer, ferrets and stoats, the fauna of Fiordland enjoyed evolutionary isolation, and eventually lost the need to fly. Today, many of the park’s native birds are on the endangered list, making the World Heritage listing even more important.

Within Fiordland National Park, some very special native species are protected. Find out more about Fiordland’s native flora and fauna here

Protecting Fiordland
Over the years, visitors have arrived in Fiordland in ever-growing numbers to see for themselves the area’s famed beauty. Thanks to New Zealand’s strong sense of conservation, places of natural beauty such as Fiordland National Park will be preserved and protected by those who live, work and visit here. It is a way to ensure all those who visit Fiordland will experience the very same wild majesty that early Māori and the tourism pioneers encountered.

FAQs about Fiordland

How was Fiordland formed?

Fiordland was formed by a combination of heat and compression, volcanic activity, seismic uplift and more recently glaciation.

What are the geographical features of Fiordland?

There are many geographic features in Fiordland including the obvious lakes, rivers, mountains and fiords. The more dramatic and mountainous areas of Fiordland are marked by U shaped valleys formed by glaciers. Other features of glaciation that you will find in Fiordland include: cirques (bowl like features) at the head of valleys - sometimes filled with water, rounded off islands in fiords or lakes (ie the Dome Islands on Lake Te Anau), hanging valleys, and moraine (rock debris left behind by glaciers).

How was Milford Sound formed?

Piopiotahi / Milford Sound was formed by glaciation between 80,000 and 12,000 years ago.

How big is Fiordland?

Fiordland National Park is now over 1.2 million hectares in size, and encompasses mountain, lake, fiord and rainforest environments.

What is Fiordland most famous for?

Fiordland is most famous for Piopiotahi / Milford Sound, often described as "the eighth wonder of the world". Fiordland is also famous for the Milford Track, known as "the finest walk in the world". Fiordland is part of Te Wahi Pounamu - Southwest New Zealand World Heritage site. This status affords Fiordland fame and protection for generations to come.
