SONY DSC

LÉ Aoibhinn (EE-vin, Irish: [ˈiːvʲən̠ʲ]) is a Lake-class inshore patrol vessel of the Irish Naval Service. Under the name HMNZS Rotoiti it was used for border and fishery protection patrols by the Royal New Zealand Navy from 2009 to 2019. Together with its sister Pukaki, the vessel was sold to Ireland for use by the Irish Naval Service in 2022. Rotoiti was renamed and commissioned into Irish service in September 2024.

New Zealand service

[edit]

The vessel was fitted out in Whangārei 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]

Irish service

[edit]

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.[4] Rotoiti was commissioned into Irish service, as LÉ Aoibhinn,[5] in September 2024.

HMNZS Hawea

HMNZS Hawea is a Lake-class inshore patrol vessel of our Royal New Zealand Navy. It is one of the Navy’s two Inshore Patrol Vessels (IPV). The ships are designed for maritime surveillance and patrol missions around New Zealand’s 15,000-kilometre coast and out to the 200 nautical mile limit of our Exclusive Economic Zone (EEZ).Royal New Zealand Navy's HMNZS Hawea sailing on the sea

HMNZS Hawea’s primary mission is to ensure the security and prosperity of New Zealanders by undertaking maritime security patrols, surveillance, boarding operations and response to search and rescue call-outs.

Conceived as part of Project Protector, the Inshore Patrol Vessels were built in Whangarei by BAE Systems Australia (formerly Tenix Shipbuilding).

Hawea was delivered to the Ministry of Defence and commissioned into our Royal New Zealand Navy on 1 May 2009. Hawea is the third ship of this name to serve in the Royal New Zealand Navy and is named after Lake Hawea.

Our two Inshore Patrol Vessels, HMNZS Taupo and HMNZS Hawea, have fully automated control and navigations systems, powerful engines, modern communications and surveillance systems, active stabilisers and comfortable accommodation. Using the two RHIBs (Rigid Hull Inflatable Boats) onboard, both ships can undertake boarding operations, surveillance and transport personnel. The RHIBs are launched using two automatic davits near the stern of the vessels. The ships are highly manoeuvrable and capable of speeds up to 25 knots (46 kilometres per hour). 

They regularly work with government agencies such as Primary Industries (fisheries), Customs, Police and the Department of Conservation and frequently visit ports throughout the country.

Ship’s Badge

HMNZS Hawea Badge

HMNZS Hawea’s Badge

Motto: Kia Toa (Be Brave).

The design for this badge was submitted by the first Hawea ship, a Loch Class Frigate commissioned in 1948. The design features a Māori weapon, a kotiate with wavy lines representing the sea. The concept arises from the history of Lake Hawea which was the scene of settlement of at least four tribes who successively overcame and drove out their predecessors. A kotiate is a Māori weapon that is usually made of whale bone or hardwood and the leading edge is ground to a fine, sharp finish. The knop (end of the handle) has a carving, usually a stylized human face, and a hole through which a leather thong is fixed which is wound around the thumb to prevent the hand slipping when the jab is made.

The badge was finally approved in March 1951. The second Hawea, a Lake Class Patrol Craft also used this badge and carried out some of the important multi-agency tasks that our current HMNZS Hawea is engaged in.

Hawea was named by the Ship Sponsor, Lady Mrs Sandra O’Regan and is affiliated to the Greymouth / Westport (West Coast) region.
