Gold: The Rushes That Shaped New Zealand
Gold changed New Zealand.
In this episode of Rare Stones of Aotearoa, we follow the discoveries, rushes and people that transformed the country during the nineteenth-century search for gold, from Otago and the West Coast to the Coromandel and beyond.
We look at the places where fortunes were made and lost, the settlements that appeared almost overnight, the miners who pushed into remote valleys and mountains, and the extraordinary finds that helped shape New Zealand’s history.
This is the story of gold in Aotearoa, the geology beneath it, the people who chased it, and the legacy the rushes left behind.

Bowenite: The Long Journey for Tangiwai
Bowenite, known in Aotearoa as tangiwai, has a history that reaches far beyond geology. Found in the remote country around Piopiotahi Milford Sound and the Hollyford region, it was travelled for, traded and treasured long before European geologists gave the stone its mineralogical name. This episode follows the journeys to places such as Anita Bay and Poison Bay, the Māori routes used to reach sources of pounamu, and the later scientific story of the stone now known as bowenite.
