Vessels of the class
Altogether there were seven vessels in the class[1]
| Name | Commissioned | Decommissioned |
|---|---|---|
| HMNZS Kahu (A04) | 17 May 1988[2] | 30 October 2009[2] |
| HMNZS Tarapunga | 8 June 2000[3] | |
| HMNZS Takapu | 8 June 2000[3] | |
| HMNZS Moa (P3553) | 28 November 1983 | 23 January 2007 |
| HMNZS Kiwi (P3554) | 2 September 1984 | 11 December 2007[4][5] |
| HMNZS Wakakura (P3555) | 26 March 1985 | 11 December 2007[4][5] |
| HMNZS Hinau (P3556) | 4 October 1985 | 23 January 2007 |
The lead vessel, Kahu, was initially named HMNZS Manawanui from 28 May 1979 to 17 May 1988.[2] She was modified so she would function as a diving tender. After the commissioning of the dedicated Diving Support Tender HMNZS Manawanui (A09) she remained in service (as the Kahu) attached to the Royal New Zealand Naval College as the basic seamanship and navigation training vessel.
The next two vessels, Tarapunga and Takapu, were modified with their superstructure accommodation increased so they could function as inshore survey vessels. These were both decommissioned in the year 2000.
The last four vessels functioned as inshore patrol vessels for the Naval Volunteer Reserve. From 1994 these were modified to conduct mine countermeasures route surveying using side-scan sonar. This was used on several occasions for search-and-rescue or transport investigations. In 2005, three vessels were relocated to Auckland to fill the training gap left by the decommissioning of HMNZS Canterbury. Kiwi relocated to Auckland during 2006. On relocating, the vessels' side scan sonars were removed.
With the introduction of the Project Protector ships, Moa, Kiwi, Wakakura and Hinau were replaced by four Protector-class inshore patrol vessels during 2007 and 2008. Kahu remained in service for seamanship and Officer of the Watch training until 2009.
