This research utilises Ferdinand von Hochstetter’s unpublished November 1860 Folio of survey data from the first major terrestrial topographical and geological survey in New Zealand. The Folio data enable the reconstruction of the survey across the North Island to Lake Rotomahana, with unique bearings to the lost Pink and White Terraces. Originally prepared for the purposes of cartographic production in Gotha, Germany, the Folio
features marginalia by cartographer August Petermann. It also validates Hochstetter’s 1859 field diaries and Rotomahana Basin topography navigating to the Terraces. The Folio survey coordinates suggest the Pink and White Terrace springs lie buried beneath the shores of Lake Rotomahana. The Folio locations are consistent with earlier survey
Diary iterations. They triangulate with the Basin topography and align with Mātauranga Māori records. Complementary with other recently published research, the Folio data provides historical primary source evidence in support of the search for the lost Terraces at Rotomahana.
