Description
The Lake-class inshore patrol vessel is a ship class of inshore patrol vessels (IPVs) of the Royal New Zealand Navy (RNZN) which replaced the RNZN's Moa-class patrol boats in 2007–2008. All four vessels are named after New Zealand lakes. Following long-running Navy retention problems, two of the four vessels docked and inactive 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 In June 2019 the New Zealand Government announced that two of the patrol vessels would be withdrawn from service, and they were decommissioned in October that year.
