In June 2019 the New Zealand Government announced that two of the patrol vessels would be withdrawn from service, and they were decommissioned in October that year.

[2] The ships were built in Whangārei by Tenix Defence, and are based on a modified search and rescue vessel for the Philippine Coast Guard, with a different superstructure design.

Together with their improved speed, this will be sufficient to intercept, for example, large off-shore fishing trawlers working illegally in New Zealand waters.

[2] The shipbuilder claims "the vessel is more than capable of extending the Crown's operational envelope to Southern Ocean patrol duties".

Both Lake-class IPVs underwent restoration work to bring them to Lloyd's Classification in New Zealand before they were transported to Ireland.

[7] These ships are expected to operate primarily in the Irish Sea and off Ireland's South East coast and likely be based in the port of Dún Laoghaire in County Dublin.
