These boats perform border and fishery protection patrols.
She was fitted out in Whangarei and on 20 November 2007 started contractor sea trials. After delays due to problems with gear and fittings, she was commissioned on 17 April 2009,[1] and arrived at the Devonport Naval Base for the first time on 24 April 2009. HMNZS Rotoiti was the first of her class to be commissioned in the Royal New Zealand Navy. Rotoiti was the third boat of this name to serve in the Royal New Zealand Navy and named after Lake Rotoiti.
Rotoiti was decommissioned at Devonport Naval Base on 17 October 2019. Regulatory changes in 2012 resulted in operating restrictions around speed and sea states being imposed on them. Subsequently, the RNZN assessed them as no longer being suited to the heavy seas typically encountered off New Zealand and further afield, for which Protector-class offshore patrol vessels were more suited.[2]
In 2022, Rotoiti, along with her sister Pukaki, was sold to Ireland for use by the Irish Naval Service.[3] The two vessels arrived in Ireland in May 2023.

The New Zealand Navy stopped in to Otago Harbour for a visit yesterday as part of a voyage around numerous ports in the country.
A New Zealand Defence Force spokesman said inshore patrol vessel HMNZS Taupō had junior officers aboard undertaking the at-sea component of their basic officer of the watch course.
“This is the first course for warfare officers after they graduate from junior officer common training.”
The course runs over 16 to 20 weeks and teaches warfare officers basic principles and processes of navigation and bridge watch-keeping.

Navigation training is one of Taupō’s primary roles, alongside maritime security patrols, surveillance, boarding operations and search and rescue response, the spokesman said.
As part of the Dunedin visit, Taupō commanding officer Lieutenant Samara Mankelow will pay a courtesy visit to Dunedin’s mayor, and the crew will visit navy reserve unit HMNZS Toroa.
“Cadet Forces personnel will take tours of HMNZS Taupō and potential recruits were picked up by seaboat and delivered to the ship coming into harbour so they could ride in.
“This will be repeated in reverse when Taupo departs on Thursday”, the spokesman said.
HMAS Lachlan (K364/F364) (later HMNZS Lachlan (F364)) was a River-classfrigate that served the Royal Australian Navy (RAN) from 1945 to 1949. The vessel was later transferred to the Royal New Zealand Navy serving as surveyor until 1975 and was eventually scrapped in 1993.
During 1945, Lachlan was used during the opening of the Captain Cook Graving Dock; her bow was used to cut the ribbon across the drydock‘s mouth. In 1949, shortly before her decommissioning, she found the wreck of the SS Yongala, which sank with all 122 aboard in a cyclone in 1911. Her wreck was thought to be a shoal at that time. [1]
Lachlan was paid off on 31 May 1949. She was transferred to the Royal New Zealand Navy, renamed HMNZS Lachlan, and was a survey and Antarctic supply ship until February 1975. She was used as a “Refit Barge” with many workshops onboard until the late 1980s when she was sold to Chile to continue work as floating workshops for ships being refitted.[citation needed]
In 1948, the New Zealand government sought a survey ship to use temporarily until a new one could be built in Britain. After negotiations, Lachlan was offered on loan for an initial time of three years and on 31 May 1949 was paid off from RAN service and was immediately given to the Royal New Zealand Navy the next day. Following trials through September 1949, on 5 October 1949 HMNZS Lachlan was commissioned into the Royal New Zealand Navy.[2]
The ship was fully disarmed at the dockyard at HMNZS Philomel and the ship’s chart room enlarged for surveying. The ship was rushed into service so quickly that some of the finishing touches were done at sea. Her first survey was started on 18 November 1949 surveying the Wellington Harbour entrance, taking three weeks to complete with assistance of a survey motor boat from Australia. To assist with the creation of the hydrographic service, on earlier voyages part of the ships company included personnel from the Royal Australian Navy and Royal Navy.
HMNZS Lachlan surveyed over fifty percent of New Zealand’s coastline over her twenty years in commission. Some of her service included surveys in Australia and the rest of the Pacific, and she helped clear mines around the Gilbert & Ellice Islands from World War II. Her bow was damaged in a collision with the Napier wharf in October 1954. In 1963 the New Zealand government purchased the vessel for £16,000. By 1970, she was due to be decommissioned but in May 1970 the Royal New Zealand Navy was ordered by the government by an extra five years.
In 1975, HMNZS Lachlan was painted all grey and docked at HMNZS Philomel to house ship’s companies whose frigates were undergoing refits. In September 1975, her engines were removed and sold, and in 1993 the hulk was sold to a Philippines company for scrapping.
In 1938, the Australian Commonwealth Naval Board (ACNB) identified the need for a general purpose ‘local defence vessel’ capable of both anti-submarine and mine-warfare duties, while easy to construct and operate.[2][3] The vessel was initially envisaged as having a displacement of approximately 500 tons, a speed of at least 10 knots (19 km/h; 12 mph), and a range of 2,000 nautical miles (3,700 km; 2,300 mi)[4] The opportunity to build a prototype in the place of a cancelled Bar-classboom defence vessel saw the proposed design increased to a 680-ton vessel, with a 15.5 knots (28.7 km/h; 17.8 mph) top speed, and a range of 2,850 nautical miles (5,280 km; 3,280 mi), armed with a 4-inch (102 mm) gun, equipped with asdic, and able to fitted with either depth charges or minesweeping equipment depending on the planned operations: although closer in size to a sloop than a local defence vessel, the resulting increased capabilities were accepted due to advantages over British-designed mine warfare and anti-submarine vessels.[2][5] Construction of the prototype HMAS Kangaroo did not go ahead, but the plans were retained.[6] The need for locally built ‘all-rounder’ vessels at the start of World War II saw the “Australian Minesweepers” (designated as such to hide their anti-submarine capability, but popularly referred to as “corvettes”) approved in September 1939, with 60 constructed during the course of the war: 36 (including Stawell) ordered by the RAN, 20 ordered by the British Admiralty but manned and commissioned as RAN vessels, and 4 for the Royal Indian Navy.[2][7][8][9][1]
The majority of Stawell‘s career was spent in three areas. Initially, she served as a convoy escort along the east coast of Australia.[1] Following this, Stawell participated in a variety of escort, minesweeping, and combat roles throughout New Guinea waters.[1] On 3 August 1945 she sank an armed Daihatsu barge in the Moluccas area.[10] In the final third of her career, the ship spent time in Hong Kong waters, performing minsweeping and anti-piracy duties.[1]Stawell returned to Brisbane in November 1945.[1]
The corvette received three battle honours for her wartime service: “Pacific 1943–45”, “New Guinea 1943–44”, and “Borneo 1945”.[11][12]
Stawell was removed from RAN service on 26 March 1946.[1] On 5 March 1952, Stawell and three other Bathurst-class corvettes (HMA Ships Echuca, Inverell, and Kiama) were transferred to the Royal New Zealand Navy.[13]
She was commissioned into the RNZN during May 1952 and given the prefix HMNZS.[14]Stawell operated primarily as a training vessel until 1959, when she was placed into reserve.[1][14]
