work on the installations, sans guns, was completed behind schedule in 1944, and had by then ballooned from initial estimates of £140,000 to £327,966, excluding the costs of the guns. By 1945, the immediate threat of war had subsided, and many of the workers were transferred to work on the hydroelectric plants built on the Waikato River. By 1955, all material that could be deteriorated was removed from the site. Construction of the battery was, however, considered a major feat of engineering, carried out under particularly difficult circumstances. As the tides of war turned, only two BL 9.2-inch Mk IX – X naval guns were installed, one in 1944, and one in 1948. The third gun was cancelled before shipment. Never fired except for testing and training purposes, the guns were dismantled and sold for scrap in 1961. An extensive vineyard on the surrounding privately owned farm is also named after the installation. For almost two decades, the farm's owner had a dispute with Auckland City over public access to the reserve, finally resolved in 2002 by the Privy Council agreeing with the council's case providing public access. If one examines the lead up to the access dispute, one finds that the land owner alleged he was suffering losses through theft of his farm stock, some of which were barbecued on site, and others were trucked off the farm to be butchered elsewhere on the island. The thefts were of such a magnitude, said to be tens of thousands of dollar value per annum, that the viability of the stock fattening part of the landowner's business was being jeopardised. John Spencer, the landowner at the time, took one of the few options open to him and blocked access to his property. The battery is now in the hands of a preservation society, which keeps it open for the public under a concession from DOC. The preservation society is currently trying to source an appropriate artillery piece to restore at least one gunpit to a similar state as it would have appeared in late World War II. Characteristics The 9.2 inch guns that were once installed in two of the gun pits had ranges of 31,300 yards (over 30 km) and a possible rate of fire of one round per minute. This made them the largest guns ever used in New Zealand. Their mountings could swivel them 360° and elevate up
