The Otaki Sanatorium was opened in 1907, providing care for tubuculosis (TB) patients. Featuring wide verandas and balconies and large opening windows front and back, they enable exposure to the open air. The buildings were renovated in 1926-27, and in 1949-51 an extension to the East Deck was added.
Until 1919 the Sanatorium accommodated both male and female patients, then female-only until 1956.
Sited on a low ridge, the Sanatorium had views of the sea, Kapiti Island and the Tararua Ranges. Patients helped develop the gardens around the buildings.
Patient numbers declined over the years as TB incidence decreased and different treatment methods were adopted. 'The San' closed in 1964, with remaining patients transferred to Auckland.
