Rangitoto ki te Tonga / D'Urville Island

Separated from the mainland by the turbulent waters of Te Aumiti / French Pass, Rangitoto ki te Tonga / D'Urville Island is a rugged and remote landmass of profound historical importance. For Ngāti Koata, who hold mana whenua, it is a cultural heartland. For centuries, the island was a technological and economic powerhouse of the Māori world, as its mountains held one of Aotearoa's most prized resources: high-quality metasomatised argillite, or pakohe. The quarrying and crafting of this stone into superior tools made the island a vital centre of industry and trade, connecting it to iwi across the country.

The Pakohe Capital of Aotearoa

The island's primary significance in Māori history comes from its unique geology. It is one of New Zealand's few sources of pakohe, a hard, dense, fine-grained stone ideal for making durable and sharp-edged tools. For centuries, Māori travelled to the island to quarry this precious resource from sites high in the island's ranges. The quarried stone was then worked into high-quality toki (adzes), chisels, and other tools. These finished implements were not just functional; they were items of immense value and prestige. The pakohe tools from Rangitoto ki te Tonga were a major trade commodity, and archaeological evidence shows they were distributed and used as far away as the Auckland region and the lower South Island. This made the island a major industrial centre, its products underpinning agriculture, carving, and canoe-building throughout Aotearoa.

Ngāti Koata and Mana Whenua

Rangitoto ki te Tonga is of immense spiritual and cultural importance to the people of Ngāti Koata, who have been the island's kaitiaki (guardians) for generations. Their identity is inextricably linked to the island's landscape, history, and resources. Control of the valuable pakohe quarries gave the resident iwi great influence, wealth, and mana. The island is rich with pā sites, burial grounds, and other wāhi tapu (sacred sites) that tell the story of their long occupation. Today, Ngāti Koata continue to maintain their strong connection to the island through cultural practices, conservation projects, and their role as mana whenua.

D'Urville and Te Aumiti / French Pass

The island received its European name in 1827 from the French explorer Jules Sébastien César Dumont d'Urville. Commanding the corvette Astrolabe, d'Urville was meticulously charting the complex coastline of the Marlborough Sounds. His most famous and daring feat of this voyage was the navigation of the narrow, treacherous channel separating the island from the mainland. With its ferocious tidal flows reaching up to eight knots and a turbulent reef system, local Māori had warned him against attempting the passage. D'Urville, however, successfully guided his ship through, naming the channel French Pass (Te Aumiti) and the large island to his north in honour of himself. His charts provided the first detailed European maps of this part of New Zealand.

The Island Today

In the post-European era, parts of the island were farmed, but it has largely remained a remote and sparsely populated place, retaining much of its wild character. It is now a mosaic of public conservation land managed by the Department of Conservation, private farmland, and regenerating native bush. Its isolation has helped to protect unique ecological values, and it remains a place of rugged beauty and relative solitude. For visitors and residents alike, the island's deep cultural history and its dramatic landscapes serve as a powerful reminder of its central role in the story of Marlborough and Aotearoa.
