In the 1880s the Pink and White Terraces were the South Pacific’s premier tourist attraction: two cascades of silica basins on the shore of Lake Rotomahana, built up by geothermal springs into tiered pools of warm, mineral-blue water. Victorian travellers crossed the world to bathe in them and called them the eighth wonder. The tourism ran through the Māori village of Te Wairoa, with Guide Sophia Hinerangi of Tūhourangi leading parties across Lake Tarawera beneath the supposedly extinct mountain.
On 31 May 1886, one of Sophia’s tour parties — Māori paddlers and European tourists alike — reported watching a phantom war canoe, fully manned, drive across the lake and vanish. No such waka existed on the lake. The old tohunga (priest) of Te Wairoa, Tuhoto Ariki, pronounced it an omen: the land’s people would be overwhelmed.
10 June 1886
Shortly after midnight, earthquakes shook the district; around 01:30 Mount Tarawera’s three peaks split open, and the eruption tore southwest through Lake Rotomahana itself, opening a rift some 17 kilometres long. Where superheated magma met the lake’s water and geothermal system, the blasts turned phreatomagmatic — hurling out mud, ash, and scoria across hundreds of square kilometres. Villagers and tourists in Te Wairoa, ten kilometres away, watched fountains of fire on the mountain before the fall of hot mud began collapsing roofs.
Around 120 people died — the figure is debated, and Māori accounts suggest more — almost all of them Māori, chiefly at the villages of Moura and Te Ariki, which were buried entirely, and at Te Wairoa. Sophia’s whare, sturdily built, sheltered dozens through the night and stands among the reasons she is remembered as a national heroine. Tuhoto Ariki was dug out alive after four days — a man past 100 by local account — only to die days later.
When survey parties reached Rotomahana they found the lake blasted into a steaming crater and the Pink and White Terraces gone — destroyed or buried, a loss New Zealand has mourned ever since. (Twenty-first-century researchers have recovered pink terrace material from the modern lakebed, and whether remnants survive under the sediments remains genuinely contested.)
Afterwards
The eruption redistributed the living as well as the dead: the Tūhourangi people, their lands and livelihood buried, were taken in by related iwi at Whakarewarewa, where their guiding tradition continues today. Te Wairoa was excavated decades later as the Buried Village, New Zealand’s Pompeii-in-miniature. And in 1901 the government, mindful that the colony had lost its wonder, opened the Waimangu valley formed by the eruption as a new attraction — the world’s youngest geothermal system, still steaming in the rift Tarawera tore open.
