Wrights Hill Fortress is a counter bombardment coastal artillery battery in the Karori suburb of Wellington, New Zealand.

The fall of the shot was observed in Cook Strait and these test firings (three rounds on each occasion) were deemed a success.

In 1960, somewhat ironically, both of the guns were sold to the Japanese as scrap metal, the very nation Wrights Hill Fortress was constructed to defend Wellington against.

Under advice from the War Office in the United Kingdom, 9.2 inch guns were approved in 1934 and the Wrights Hill site selected.

Tunneling began in December, with construction initially conducted by Downer & Co Ltd. By late 1943 a manpower shortage meant that the Department of Public Works had to step in, providing men recently returned from the disbanded 3rd Division.

As the strategic situation in the Pacific became more favorable and the threat of Japanese Invasion reduced, construction of the battery slowed.

A further three windows were broken and a plaster ceiling cracked in residential properties near the fortress on Verveirs Street and were repaired by the Public Works Department.

[1] The gun pits were filled in in 1961 and the defence reserve status was lifted, although 10th Coast Regiment didn't fully relinquish control of the fortress until 1962.

[6] The New Zealand Post and Telegraph Department (later Telecom/Spark) has also used the site to set up telecommunication aerials since 1955, and continued to store equipment in some of the war shelters until 1997.

[1] The Karori Lions Club began restorations in 1988 and opened the fortress to the public for the first time on ANZAC Day 1989.

The no.1 gun pit is now completely excavated and had the bearing markings repainted, while the underground tunnel network has had the drainage system repaired and lighting installed.
