HMNZS Te Kaha

Design and construction

Main article: Anzac-class frigate

During the mid-1980s, the RNZN began considering the replacement of their four frigates. Around the same time, a deterioration in New Zealand-United States relations forced the New Zealand government to improve ties with local nations. As the Royal Australian Navy was seeking to replace their s with ships nearly identical to what the RNZN wanted, the two nations decided to collaborate on the acquisition in early 1987. Tenders had been requested in 1986, and 12 ship designs (including an airship) were submitted. By August 1987, these were narrowed down in October to Blohm + Voss's MEKO 200 design, the M class (later ) offered by Royal Schelde, and a scaled-down Type 23 frigate proposed by Yarrow Shipbuilders. In 1989, the Australian government announced that Melbourne-based shipbuilder AMECON (which became Tenix Defence) would build the modified MEKO 200 design. However, the decision to buy the frigates had been highly controversial in New Zealand, primarily because of the cost of purchasing frigate-type ships, plus the idea that the high-capability warships would be too few and too overspecialised for the fisheries and economic exclusion zone (EEZ) patrols expected to be the RNZN's core operations. Despite ongoing debate, the New Zealand government agreed to purchase two frigates in addition to the RAN's eight, and had an option for two more. This option expired in 1997 without New Zealand exercising it; there were proposals to buy a new or second-hand Anzac outside the terms of the original contract, but a lack of political support stopped this developing, and the number built for the RNZN remained at two. The drop in capability and the issue of tying up the Anzacs on EEZ patrols when they could be deployed more suitably elsewhere were factors leading to the RNZN's Project Protector acquisition program.

The Anzacs are based on Blohm + Voss' MEKO 200 PN (or ) frigates, modified to meet Australian and New Zealand specifications and maximise the use of locally built equipment. The ships are 109 m long at the waterline, and 118 m long overall, with a beam of 14.8 m, and a full load draught of 4.35 m. Maximum speed is 27 kn, and maximum range is over 6000 nmi at 18 kn; about 50% greater than other MEKO 200 designs. The standard ship's company of an Anzac consists of 22 officers and 141 sailors.

As designed, the main armament for the frigate is a 5-inch 54 calibre Mark 45 gun, supplemented by an eight-cell Mark 41 vertical launch system for RIM-7 Sea Sparrow surface to air missiles, two 12.7 mm machine guns, and two Mark 32 triple torpedo tube sets firing Mark 46 torpedoes. The New Zealand Anzacs initially operated with a Westland Wasp helicopter, which were later replaced by Kaman SH-2 Seasprites, then Kaman SH-2G Super Seasprite helicopters.

Te Kaha was laid down at Williamstown, Victoria on 19 September 1994. This problem, which was common to the first four ships of the Anzac class, was later rectified.

Operational history

In 1999, Te Kaha pursued Patagonian Toothfish poachers in the Ross Dependency, participated in the INTERFET multinational deployment to East Timor from 19 to 26 September, and operated as part of the Multinational Interception Force in the Persian Gulf.

The frigate was also involved in the Solomon Islands conflict during 2000 and 2001, with several periods as guardship at the capital, Honiara.

In 2002, Te Kaha returned to the Persian Gulf, this time as part of Operation Enduring Freedom, after a four-month flag-showing deployment in Asian waters. The frigate was replaced in the Gulf by Te Mana in early 2003.

In 2010 Te Kaha and became the first RNZN ships to Visit the USA Mainland since the dissolution of the ANZUS treaty.

In 2012 Te Kaha attended Exercise RIMPAC.

On 16 February 2015, Te Kaha sailed from New Zealand to Gallipoli, ahead of the 100th Anniversary of the landings there during World War I. After completion of this event, the frigate sailed for the Gulf of Oman where she was assigned to anti-piracy patrols. Following this, she sailed back to New Zealand after participating in the Australian-led exercise Exercise Talisman Saber. The ship returned to New Zealand on 2 August 2015 to family members, senior naval staff and the Maori Cultural group who performed a haka. Also involved in Talisman Saber 2015 was the multi-role vessel, and the fleet tanker, HMNZS Endeavour.

In June 2017, the ship's deployment in the western Pacific was extended to provide support to the US 7th Fleet after collided with the container ship , killing seven sailors and causing extensive damage to the destroyer. The frigate directly contributed to the escort of , an aircraft carrier replacing in the region.

In September 2021 and Te Kaha sailed for an international defence exercise in South East Asia and also interact with the United Kingdom’s Carrier Strike Group (CSG) as it conducts engagement activities in the Indo-Pacific region.

Refit

In March 2018, Te Kaha arrived in Victoria, British Columbia, to undergo a major upgrade of her combat management system to the Lockheed Martin CMS 330, as well as replacing the RIM-7 Sea Sparrow with the new Sea Ceptor surface-to-air missile. The upgrade is expected to cost NZD639 million. In September 2020, the refit of Te Kaha was reportedly complete and the ship began post-upgrade sea trials in preparation for a return to active service.

In December 2020 Te Kaha completed initial refit upgrades and sea trials and sailed back to Auckland, arriving at the Devonport Naval Base on 20 December. While she has finished the upgrades she has not completed her maintenance routine.

Te Kaha suffered minor damage to its bow in May 2024 when it collided with the wharf at Kauri Point Armament Depot. The damage cost $NZ220,000 to repair.

The frigate departed New Zealand on 12 February 2025 for a deployment to the Middle East.

On 4 April 2025, HMNZS Te Kaha conducted a PASSEX with the of the Indian Navy. The exercise concluded New Zealand led-CTF 150 Joint Focused Operation ANZAC Tiger and included cross-deck landings, boarding drills, and manoeuvres to enhance bilateral maritime interoperability and cooperation.

Honours

In November 2018, the US Navy awarded Te Kaha the Meritorious Unit Commendation for supporting the 7th Fleet after the Fitzgerald collision.
