Lake-class inshore patrol vessel
The Lake-class inshore patrol vessel (also known as the Rotoiti class and the Protector class) is a ship class of inshore patrol vessels (IPVs) of the Royal New Zealand Navy (RNZN) and planned for the Irish Naval Service which replaced the RNZN's Moa-class patrol boats in 2007–2008. All four vessels are named after New Zealand lakes.

| Notes | |
Following long-running Navy retention problems in the wake of NZDF "civilianisation", two of the four vessels were tied up, inactive, in a 'Reduced Activity Period' for long periods between 2013 and 2018. In June 2019 the New Zealand Government announced that two of the patrol vessels would be withdrawn from service, and they were decommissioned in October that year. Both were later sold to the Irish Naval Service.
