Never finished the refit

Contracts were awarded in 1941 to four Auckland boatyards to construct a total of 12 Fairmile Class B anti-submarine motor boats. Plans and prefabricated keel framing were provided by the British Admiralty and the hull, decking and superstructure were to be completed with local timber. The stem and sternposts were formed from Pohutukawa and the hull was two layers of Kauri planking. Engines, ordnance and many fasteners and fittings used in their installation were also imported from UK. The first Fairmile was finished in Oct-42 and the last by Dec-43 and along the way there were delays in shipping of components and obtaining sufficient Kauri that prevented the project being completed sooner. During this time the vessels began coastal patrols with six based in Auckland, four in Wellington and two from Lyttelton.
However by the end of 1943 there was little further threat of enemy attack in the vicinity and in January 1944 it was agreed to deploy all the Fairmiles to the Solomon Islands and under the control of US Navy. They sailed in three groups during late February via Noumea and arrived together at Russell Islands in early March organised as the 80th ML and 81st ML flotillas. They commenced anti-submarine patrols in the Guadalcanal, Tulagi and Russell Islands area. The launches added to the existing RNZN presence in the Campaign as the 25th Minesweeping flotilla had already seen much action there .The NZ Army 3rd Division were also deployed nearby as were squadrons of RNZAF aircraft. The Fairmiles continued on patrol and escort duties in the region until they were withdrawn in July-45 and although there had been operational accidents they never engaged in battle with Japanese forces. Consequently all 12 returned to NZ and except for Q411 were soon up for tender.

Many of the Fairmiles were a familiar sight on Auckland Harbour and provided reliable public transport for decades after their military service was over. Generations of Aucklanders enjoyed the excursions on them around the islands of the Gulf. I haven’t yet found mention about the fate of Q404 and Q407 nor if Q402 and Q408 are still afloat. I’m looking forward to any news about their recent history and current status. But it appears that only Q406 and Q411 remain in NZ.
Kahu may have been the last chance for preservation but too late
