# Coastal fortifications of New Zealand

Coastal fortifications were constructed in New Zealand in two main waves: around 1885 as a response to fears of an attack by Russia, and in World War II due to fears of invasion by the Japanese.
The fortifications were built from British designs adapted to New Zealand conditions. They typically included gun emplacements, pill boxes, fire control or observation posts, camouflage strategies, underground bunkers, sometimes with interconnected tunnels, containing magazines, supply and plotting rooms and protected engine rooms supplying power to the gun turrets and searchlights. There were also kitchens, barracks, and officer and NCO quarters.

## The "Russian-scare" forts of 1885

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. The article proclaimed that war had been declared between England and Russia, 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.
The Southern Cross article created panic and the Government commissioned its first reports on the colony's defences. It was now clearly understood that Britain would protect its territories and vital shipping routes, but the defence of individual ports was the responsibility of each self-governing colony. Then Russia declared war on Turkey in 1877 producing another "scare".
An 1884 report by Sir William Jervois, the Governor of New Zealand, included recommendations for military forts to be constructed at the country's four main ports at Auckland, Wellington, Lyttelton and Port Chalmers. These coastal artillery fortifications or land batteries were to be based on British designs. Heavy artillery pieces and ammunition was ordered from Britain. By 1885, work started in earnest on the construction of what eventually became seventeen forts, further encouraged by yet another Russian scare.

### Artillery

In 1885 the New Zealand Government bought ten Armstrong BL 8-inch and thirteen Armstrong BL 6-inch guns on disappearing carriages. The disappearing gun was the very latest in military technology in the 1880s. It was "disappearing" because as it fired, the recoil pushed the gun back underground where it could be reloaded under cover. The total costs of this artillery plus the costs of installation including land, emplacements, magazines and barracks was about £160,000.
Following the "second Russian scare" a number of additional RML 7-inch and 64-pdr guns were also installed
| Artillery circa 1890 | Number | Range | Notes |
| Armstrong BL 8-inch Mk VII disappearing guns | 10 | 4 miles | Weighed 13.5 tons and fired a 180-pound shell. |
| Armstrong BL 6-inch disappearing guns | 13 | 3 miles | Weighed 5 tons and fired a 100-pound shell. |
| RML 7 inch 7 ton guns | 11 | | Weighed 7 tons. |
| RML 64-pdr Mk 3 guns | 9 | 2 miles | Weighed 64 cwt |

## 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.

### Ordnance

The fortifications were equipped with both old and new ordnance, mostly British. Some World War I ordnance was requisitioned from museums and recommissioned.
| Ordnance used during World War II | Number | Range | Notes |
| 9.2-inch guns | 6 | 18 miles | |
| BL BL 6 inch Mk 24 guns | 3 | 14 miles | |
| BL 6 inch Mk 21 guns | 6 | 13 miles | |

| QF 6-pdr guns | 12 | 5 miles | |
| Bofors 40 mm guns | 48 | 4 miles | |
| CASLs | 48 | | Coastal Artillery Searchlight |

### The fortifications

The fortifications were administered by the Royal New Zealand Artillery, which grouped them into four areas. Each area was under the command of a heavy artillery regiment. Within each regiment the fortifications were grouped into batteries.
* Also used (highlighted below in yellow) were seven of the now historic Russian scare fortifications

#### Upper North Island

Under the command of the 9th Heavy/Coast Regiment.
| Battery | Name | Way- point | World War II Ordnance | Range (miles) | Dates | Notes |

By World War II, with ships' guns able to fire long distances, the old fort was too close to the city it was meant to defend. New batteries were built at Motutapu, Castor Bay, Whangaparaoa and Waiheke Island and North Head became the centre of administration. A complex of tunnels, guns, searchlights and other fortifications remain and it is now a historic reserve managed by the Department of Conservation. |
| 61 | Bastion Point [Russian scare] | 36°50′43″S 174°49′29″E﻿ / ﻿36.84528°S 174.82472°E﻿ / -36.84528; 174.82472﻿ (Bastion Point) | 2 × 12-pdr gun Twin 6-pdr guns 3 × CASLs | 8 | 1885– | Located in Mission Bay. The fortifications were buried in the 1940s when the Michael Joseph Savage memorial was built, and effectively forgotten. The underlying tunnels were later rediscovered. |

Accommodation was at the end of Harvey Road, with only concrete pads remaining for some buildings. Due to the erosive nature of these compacted sandhills the gun emplacement was undermined and slipped down the cliffs in the early 1980s. According to local residents, the gun was only fired 6 times, cracking the concrete abutments. |
| 61 | Motuihe Island | 36°48′40″S 174°49′29″E﻿ / ﻿36.81111°S 174.82472°E﻿ / -36.81111; 174.82472﻿ (Motuihe Island) | 2 × 4in Mk 7 guns | 9 | 1872– | During World War II (1941) the Motuihe buildings became HMNZS Tamaki naval base, a training establishment. Now in the care of the Department of Conservation. |

## Post war

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).
