Coastal fortifications of New Zealand

In the 1870s New Zealand was a young self-governing colony of Britain. It had developed no coastal defences of any consequence and was becoming increasingly sensitive to how vulnerable its harbours were to attack by a hostile power or opportunistic raider. Fears of invasion by the expanding Russian Empire were common, especially due to the founding of Russia's Pacific port at Vladivostok. Fears intensified after a hoax article was run in the Daily Southern Cross on 18 February 1873. and that a fictional Russian naval cruiser, the Kaskowiski, had attacked Auckland. [The Kaskowiski] – whose very name should have made sober readers suspicious – had allegedly entered Auckland Harbour on the previous Saturday night and proceeded to capture a British ship, along with the city's arms and ammunition supply, and hold a number of leading citizens for ransom. The 954-man Russian vessel obviously meant business, with a dozen 30-ton guns as well as a remarkably new advance in warfare, a paralysing and deadly "water-gas" that could be injected into enemy ships from a great distance. Following the "second Russian scare" a number of additional RML 7-inch and 64-pdr guns were also installed The forts ==World War II coastal fortifications==

The second main wave of building coastal fortifications occurred during World War II. This was mainly a response to a perceived threat of invasion by the Japanese after the attack on Pearl Harbor. From 1942 until 1944, when the threat receded, 42 coastal artillery fortifications or land batteries were either developed using historical fortifications or were built from scratch. The fortifications were built from British designs adapted to New Zealand conditions. Radar was installed which allowed long range shooting at night and replaced the traditional fortress system of range finding. Lower North Island Under the command of the 10th Heavy/Coast Regiment.

The advent of air warfare and missiles made these forts redundant and most were decommissioned by the 1950s. Godley Head continued because of compulsory military training and last fired a gun in 1959. The Department of Conservation has the remains of around 30 installations on land it manages. ==Postscript==

None of the forts fired a gun in anger, though in October 1939 a Battery Point gun at Lyttelton accidentally sank the fishing boat "Dolphin" and killed its skipper. In 1972 the United States declassified a contingency plan for invading New Zealand. This plan consisted of a 120-page intelligence document called Naval War Plan for the Attack of Auckland, New Zealand. The intelligence for the report was gathered during the visit of the Great White Fleet to Auckland over six days in 1908. The plan advocated Manukau Harbour as the best invasion point and landing heavy guns on Rangitoto Island to shell the forts on the North Shore. The plan was not very realistic and may have been an exercise to keep young officers busy (see United States war plans; which allocated the colour Garnet to New Zealand as part of War Plan Red). ==See also==
