The house and grounds remained in private hands until 1932, when they were purchased by Governor-General Viscount Bledisloe and donated to the nation.

These were successful in 1932, when Bledisloe made his purchase, and the house was subsequently restored by leading architect William Henry Gummer.

The grounds contain a carved whare runanga (meeting house) and the large waka taua (war canoe) Ngā Toki Matawhaorua, both built for the 1940 celebrations.
