VOEA Neiafu (P201) was a Pacific Forum patrol vessel operated by Tonga from 1989[1] until its decommissioning in 2020.
[2] When the United Nations Convention on the Law of the Sea extended maritime nations' exclusive economic zone (EEZ) to 200 kilometres (110 nmi), Australia designed and built 22 patrol vessels for 12 of its fellow members of the Pacific Forum.
This allowed its neighbours to exercise sovereignty over their EEZ, intercept smugglers, poaching fishers, and provide emergency services.
Australia will replace Neiafu and her two sister ships with two slightly larger and more capable vessels between 2019 and 2020.
[4] The 31.5-metre (103 ft) vessels displace 162 tonnes, and are built using commercial off-the-shelf (COTS) equipment, instead of more expensive, high-performance, military-grade equipment, to ease the maintenance burden, since local maintenance will be performed in small, isolated shipyards.
