In the June 2018 edition of Surveying+Spatial journal, I reported on Ferdinand von Hochstetter’s (1829−1884) 1859 survey of the Pink and White Terraces. This article reports new research findings on the survey, completing our study into the Terrace locations. Hochstetter remains the only terrestrial survey of this lost Eighth Wonder of the World: providing the only primary location evidence. We first summarise the six survey methods Hochstetter may have employed. Next, we report primary evidence of his second Lake Rotomahana observation station on Puai Island. Our evidence-based lakes’ altimetry is updated. We reconcile the incorrect coordinates on August Petermann's (1822−1878) 1864 Rotomahana map and reintegrate it with Hochstetter's mapping. His method-of-squares map scale is calculated from his paper stock. Our final, survey iteration/replication uses all 14 surviving survey landmarks. Lastly, the third Black Terrace location is refined. The findings are consistent with the 2018 Surveying+Spatial article by Bunn, Davies and Stewart (Bunn et al, 2018) i.e. the Black Terrace lies buried on land and the Pink and White Terraces locations lie across the shore.
