It's a long winded vessel type description, however this is the proposed vessel that is intended to replace the HMNZS Resolution and HMNZS Manawanui.

Design Background
1.1. The RNZN currently operates the HMNZS Resolution which was launched in 1989 for the role of hydrographic survey and the HMNZS Manawanui which was launched in 1969 for the role of dive support. Due to the age of these vessels and their planned decommissioning the RNZN requires a new vessel to undertake their respective roles. As proposed in the 2010 Defence White Paper both of these vessels will be replaced with a single Littoral Warfare Support Capability (LWSC) vessel.
