Built as a family refuge that was never needed, the Cameron Blockhouse stands beside State Highway 3 at Marangai, just south of Whanganui.
The farmer John Cameron put up this timber blockhouse during the New Zealand Wars, when settlers in the district feared an attack by forces led by Titokowaru. Its walls were packed with clay to stop bullets and fire, and it was placed so its occupants could signal to neighbouring blockhouses.
After decades as a farm building it was restored by volunteers, and today it is a Category 1 historic place that is open to the public.

About the Cameron Blockhouse
John Cameron built the blockhouse in 1868 as a place of refuge for his family. That year the district’s settlers feared an attack by Titokowaru, whom Whanganui District Council’s heritage inventory describes as a Māori leader who campaigned against the Crown’s alienation of Māori land.
Heritage New Zealand calls the building a rare surviving example of a blockhouse built privately rather than by the government.
The blockhouse was sited so that its occupants could signal to two other blockhouses, belonging to the Campbell and Morgan families, which in turn could relay messages to the York Stockade in Whanganui. In the end it never came under attack.
With the danger passed, the building was put to farm use as a barn, shed and stables for many years, and part of its east gable wall was removed. That section was partly reinstated around 1979, and between 1988 and 1990 the Wanganui branch committee of the New Zealand Historic Places Trust and other volunteers restored the whole building.
A Heritage Covenant was placed on the property in February 1996 to help protect the blockhouse. Today the Whanganui Regional Heritage Trust maintains the site.
The Building
The blockhouse is a timber building with a corrugated iron roof and an attic space above the main floor. Its walls were packed with clay to absorb bullets and resist fire.
Visiting
The Whanganui Regional Heritage Trust describes the blockhouse as open every day and free to visit. It is signposted on State Highway 3 at Marangai. From the small car park beside the farm drive, you walk down to the door on the north side of the building.
