The Protector-class offshore patrol vessel (also known as the Otago class) is a ship class of two offshore patrol vessel (OPVs) operated by the Royal New Zealand Navy (RNZN) since 2010. The ships are named and .

Key dates

The Ministry of Defence issued invitations to register in July 2002 and signed a contract with Tenix Defence (later BAE Systems) in July 2004. The first steel was cut in February 2005 and the first OPV HMNZS Otago was launched on 18 November 2006 in Melbourne, Australia.

While the ships are capable of carrying the SH-2G Seasprite on 30 October 2007 the NZDF announced the acquisition by NZDF of A109 light utility helicopter for training and deployment on RNZN ships including OPVs.

In September 2008 the Minister of Defence announced delays in delivery of the two OPVs due to questions regarding the ships' seaboats and Lloyds Certification. He says the issue is under negotiation with BAE (ex-Tenix). In May 2009, mediation between the Ministry of Defence and BAE Systems commenced, with the main issue being the estimated 300 tonnes increase in weight which could cause potential hazard when OPVs are in ice in Antarctica as the weight increased over the life of the vessels.

On the 18 February 2010 Otago was accepted into the Royal New Zealand Navy. NZ Ministry of Defence claimed the overweight issue was not as bad as previously thought, but "weight will have to be carefully monitored during the ship's life". The vessel was scheduled to arrive at Devonport (Auckland) Naval Base on 26 March 2010. Wellington was accepted on 6 May 2010 and arrived at Devonport later that month. HMNZS Otago arrived at Devonport Naval Base after further delay in Australia due to engine problems, which were fixed under warranty.

Design origin

Conceived as part of Project Protector, the Ministry of Defence project consisted of acquiring one multi-role vessel, two offshore and four inshore patrol vessels. The Project Protector vessels will be operated by the RNZN to conduct tasks for and with the New Zealand Customs Service, the Department of Conservation, Ministry of Foreign Affairs and Trade, Ministry of Fisheries, Maritime New Zealand, and New Zealand Police. The Government and Navy policy was the OPVs are intended to carry out resource protection functions in the EEZ, South Pacific and Southern Ocean, to free the two s for other needs. However, with the capability to carry and sustain a missile armed RNZN helicopter they do have limited higher contingency capability.

The vessels were designed by Vard Marine (known as STX Canada Marine and formerly Kvaerner Masa Marine) and are based on earlier OPV designs in service with the Irish Naval Service (since 1999) and the Mauritian Coast Guard (since 1996). However the adopted design is considerably upgraded, in that the Irish Naval Service no longer included helicopter facilities in its designs after the failure of helicopter operations from the OPV in the rough seas off the Irish west coast. Otago, however, includes helicopter facilities similar to the arrangements of the earlier Irish OPV, LÉ Eithne, which were based on the British Leander, which modification to operate larger Lynx/Seasprite helicopters is based on the design of the last RNZN Leander, . The vessel is compliant with all of the operational requirements for patrol and response, cargo carriage and handling, sea keeping for sea boat and helicopter operations, and has a high level of comfort for crew and client agency officials.

Since 2014, after the takeover of STX Marine by Vard Group of Norway, which is part of Fincantieri, the design is now referred to as the Vard 7 85M.
