Short Ship History

Early years

Otago arrived in Dunedin in January 1961 having voyaged via Suez, Singapore and Australia.

Otago took part along with her sister frigates: Taranaki and Blackpool in regular deployments to the Far East, North America, Hawaii, Australia and the Pacific Islands to participate in exercises with ships of other navies and ‘show the flag’ tours.

She also participated in ceremonial occasions including Royal Tours, Waitangi celebrations and some search and rescue work around New Zealand. Supply missions to outlying islands such as Raoul and Campbell were also on the itinerary.

In February 1964, Otago along with Pukaki and Rotoiti sank the hull of the old New Plymouth dredge Paritutu with gunfire off Cuvier Island. Later that year Otago with Pukakai as back up carry out ‘picket duty’ or advance warning south of Campbell Island for an American aircraft making an emergency flight to Antarctica and back.

Mururoa

In July 1972 the Norman Kirk led Government sent Otago into the French nuclear testing zone at Mururoa to protest the continued atmospheric testing. Otago was on station for three weeks until relived on 25th July By HMNZS Canterbury. Otago returned to Auckland in August 1973.

Fisheries

Otago carried out EEZ (Exclusive Economic Zone) patrol voyages from the zone’s introduciton in October 1977 until HMNZS Taranaki re-entered service.

Modifications and Refits

Otago’s Seacat sea-to-air missile systems were fitted in 1962-63 – her first test firing was held on 21 January 1963. Otago had a major 12-month refit from November 1966 during which her damaged bow was replaced; she was recommissioned in November the following year.

Mishaps

Otago received a badly damaged bow at pearl Harbour in August 1964 when she ran between the sterns of the double-berthed US destroyers Jenkins and Walker, while berthing.

She was repaired for service in four weeks.

Otago damaged her bow again when she struck the Suva wharf in December 1968. Three years later in August 1971 whilst in Hong Kong she sustained minor damage when Typhoon Rose hit the area.

Disposal

Otago decommissioned at Devonport in November 1983 and was slowly stripped. In July 1987 she was sold to Pacific Metal Industries Ltd and the following month she towed across to the Western Viaduct for demolition which was completed in four months.
