The Royal New Zealand Navy in the Interwar and WW2
Circa 120 ships since the 1860s
The commonwealth underdog: When thinking of commonwealth navies during the war, the three major fleets often cited were the RCAN or Royal Canadian Navy, the RAN or Royal Australian Navy, and the RNZN.
By pure laziness and reference to WW1 it was placed in the same bag as the RAN, and summup as the “Anzac navy”. It was true that during the great war, twenty years earlier, the RNZN did not existed. The population of New Zealand back then was not statistically large enough to justify the creation of a fully fledged navy. Instead, like for the Army, volunteers from the island chose to join the ranks of the RAN, which was an independent entity by that time; although many served with a battlecruiser and minor ships. The force grew in the interwar and really took off from 1941. During WW2, the Kiwi navy took part in many engagements, starting with the battle of Rio de la Plata, against the corsair Graf Spee, against the Regia Marina in the Mediterranean and across the Pacific, starting at Guadalcanal.
Timeline of the Royal New Zealand Navy
The Royal Navy ceased to assume the protection of New Zealand from the treaty of Waitangi in 1840 when the territory became a fully-fledged colony. British ships would stop however for some time, but there was never any considerations given for a permanent fleet. The settlers bought a gunboat after 1856 and the Waikato Flotilla operated from 1860, backed by a Naval Artillery Volunteer corps to provide harbour defence. In 1884 four spar torpedo boats were purchased and from 1887 ships of the Australasian Auxiliary Squadron were also funded by the government. Outside the Maori wars however (1845-1872), there were few occasions for the ‘Kiwis’ to take part in military actions before the Great War.
To support operations, an had hoc force was constituted with eight river boats, four armoured barges, five coastal boats and a naval dockyard. In 1863, the Australian-built Pioneer, built in Sydney, is followed by two sister ships, Koheroa and Rangiriri. In 1907, the local government acquired the NZS Amokura to start training cadets. This was the first commissioned ship for the local naval force, now part of a Dominion, a separate entity within the commonwealth and no longer a colony.

The New Zealand Naval Forces (1913)
In 1909 the NZ Government showed its implication in the “dreadnought race” and loyalty to the crown, by financing a battlecruiser in construction, named accordingly HMS New Zealand. Many Kiwis enlisted in the Royal Navy to serve onboard and the ship had a significant career, taking part in the battles of Heligoland, Dogger Bank and Jutland. Odd fact, she once collided with HMAS Australia in 1916 but was repaired just in time to participate to the greatest naval battle of the XXth Century.
She was part of a distinctive naval force, the New Zealand Naval Forces created in 1913, and integrated during wartime in the RN. By the Defence Act 1913, through the will of James Allen (photo), the minister of defence, the local naval force created needed ships, for which the government purchased a first cruiser to make its core, HMS Philomel. This was a relatively old (1890) Pearl class, second class cruiser.
But her career was amazing, stretching until 1949, some 60 years. Even before 1913, the HMS Philomel has had an amazing career, taking part in the Anglo-Zanzibar War, her crew capturing the palace, the infamous Benin Expedition, Second Boer War and Battle of Colenso before being transferred to the Mediterranean and be transferred in 1913. Her first duty, under Cdt Percival Hall-Thompson was to train cadets of the future navy, she was later tasked to be the centerpiece of the New Zealand forces dispatched to occupy German Samoa.
She was part of the New Zealand Expeditionary Force, escorting convoys to Australia, and up to the Middle East, chasing the ellusive cruiser Emden en route. She escorted French troopships to Port Said and was based here and sailed later to Malta, for an overhaul lasting until January 1915. Later her landing party met a superior Turkish force in southern Turkey, and the force had its first casualties. She served also in the Red Sea and in the Persian Gulf, and went on patrolling and escorting convoys in the Indian Ocean and red sea until March 1917, when she was partially disarmed, her British crew repatriated, and recommissioned as a depot ship in Wellington for minesweepers. HMS Philomel would serve from 1921 as a training base, and by 1925, her boilers and engines were removed to create more accommodation space. As a base she survived until 1941, and be recommissioned as HMNZS Philomel.
New Zealand Division of the Royal Navy (1921-41)
After the war, in 1921 this unit became the Royal Navy New Zealand Division. The latter grew to a strenght of fourteen ships. At first, the cruiser Chatham along with the sloop Veronica were acquired in 1920, and later in 1922, the sloop Torch and HMS Laburnum, then HMS Dunedin in 1924 and two years later, HMS Diomede and the minesweeper HMS Wakakura. But by far the most impressive acquisitions were the cruisers HMS Achilles (joined 31 March 1937) and HMS Leander. Both were soon famous cruisers of the Leander class. They replaced HMS Diomede and Dunedin from 1937.
Creation of the Royal New Zealand Navy on 1st october 1941

While in September 1939 the RNZN formally declared war on Germany, the Navy had little time to prepare, but the HMS Achilles would strike the first blow, participating in the first naval battle of WW2: The famous duel with KMS Graf Spee. The cruiser faced the six 280 mm naval guns of the hybrid German “pocket” battleship alonsgide HMS Ajax and HMS Exeter this 13 December 1939.
Due to the lower range and smaller guns of both Leander class cruisers, the Graf Spee concentrated fire on the 8-in armed Exeter, damaging her badly to the point both light cruisers surged to the rescue, spreading a salvation through intense counter-battery fire from their combined sixteen 6-inches and a thick smoke cloud. This forced the Geran ship to divert fire on the Ajax and Achilles closing to 13,000 yd (12,000 m), saving the wounded heavy cruiser from certain destruction. Later on, both cruisers would shadow the Graf Spee to Montevideo and were part of the blockading fleet.
When the Royal New Zealand Navy was created, the ship was recommissioned HMNZS Achilles and served in the Pacific with the USN, closer to home. The Japanese threat was really present indeed, and the RAN also largely participated in the early heavy fightings against an unstoppable IJN. Achilles was bombed off New Georgia, repaired, and served until V-Day with British Pacific Fleet. Despite the reluctance of Prime Minister Peter Fraser the Navy was now fully independent. The other transferred cruiser, HMNZS Leander, soldiered with the the New Zealand Expeditionary Force sent in the Mediterranean from 1940, the Red Sea, and the Indian Ocean. She sank there the Italian auxiliary cruiser Ramb I and was sent in the Pacific later, helped destroying the Japanese cruiser Jintsu before being torpedoed at the battle of Kolombangara, which sent her in repairs until the end of the war.
Other wartime actions of the Royal New Zealand Navy
As the war progressed, the RNZN grew in size up the end of the war accumulating over 60 ships in service. These New Zealand vessels participated in the British and Commonwealth fight in Europe and in the Pacific. Many of these ships also played their part in the defence of New Zealand home waters. The NZ ships mostly searched for German raiders, and others patrolled for any sign of a threat of Japanese invasion in 1942.
HMNZS Monowai in Milford Sound in February 1933 (top) and in WW2.
Merchant ships were requisitioned by the government and added to the Navy list pressed in defence with various armaments added. Probably one of the most prominent was HMNZS Monowai. This armed auxiliary cruiser saw action against IJN submarine I-20 off Fiji in 1942, which torpedoed but missed her. This former Peninsular and Oriental Steam Navigation Company (P&O) merchant vessel was rearmed and operated from Devonport Naval Base in Auckland. She has been requisitioned by 21 October 1939 but only operational in August 1940. She was later requisitioned by the British Ministry of War Transport and converted as a Landing Ship, Infantry (Large) and reconverted, operating in 1943-44.
In 1941–1942, an agreement between New Zealand and the United States made the RNZN Pacific command integrated into the United States Navy’s South West Pacific Area command. NZ ships joined the United States 7th Fleet Task Force.
HMS Gambia 1945
In 1943, the Crown colony class cruiser HMS Gambia was transferred to the RNZN. HMNZS Gambia was by far the most potent vessel of the RNZN by November 1944. She joined the brand new British Pacific Fleet, a joint British Commonwealth military formation formed in Sydney. Gambia and Achilles joined the new unit, taking part in the Battle of Okinawa and Sakishima Islands campaign. By August 1945, HMNZS Gambia carried the officials and representative of New Zealand at the surrender of Japan.

As part of the 7th TF, RNZN Achilles and Leander participated to Operation WATCHTOWER, covering landings landed on Guadalcanal in 7 August 1942. Followed six major naval engagements, Savo Island 8/8/1942, the Eastern Solomons 24/8/1942, Cape Esperance on 11-12/10/1942, Santa Cruz Islands 26/10/1942, Guadalcanal 12-15/11/1942 and Tassafaronga 30/11/1942. At Guadalcanal in January 1943, Kiwi and Moa spotted and targeted the IJN submarine I-1 (Eiichi Sakamoto). TF17 was constituted around USS Yorktown under read-admiral Frank J. Fletcher.
Kiwi grenaded the submarine, succeeding in disabling the I-1 port electric motor and flooding her aft storeroom. However later she emerged and escaped during the night, only to be spotted again and fired upon, and later even rammed thrice by Kiwi. The small converted Tug did caused sufficient damage with Moa to sink the IJN submarine, earned a DSO for C. BUCHANAN, signalman by admiral Halsey.
HMNZS Achilles and Leander escorted convoys of troops and supplies to Guadalcanal while the 25th Minesweeping Flotilla (HMNZS Matai, Tui, Moa, Kiwi) started their ASW patrols from December 1942. On 5 January 1943 HMNZS Achilles X-turret was hit by a bomb and during the night of 29-30 January 1943, HMNZS Kiwi and Moa eventually sank (as seen above) the sink Japanese submarine I-1, but the latter was avenged as Moa was sank on 7 April 1943 at Tulagi. By 13 July, Leander was badly damaged at the Battle of Kolombangara but was later repaired at Boston. As remembered by Petty Officer Brown, night fighting over IJN supplies was near constant around Guadalcanal.
The RNZN would have the occasion of firing the last shots of WW2: Petty Officer Wireman R.B. Harvey remembered the bombardment of HMNZS Gambia of Kamaishi. Lieutenant S.W. Hicks RNZNVR also remembered the unknown massive IJN submersible they crossed with HMNZS Monowai at the Suva Harbour entrance, fired upon but not sank on 16 January 1942. Among the POWs in January 1945 were a significant numbers of RNZN Fleet Airmen. They were murdered in Singapore in July 1945.
