Three stations were established, at Ranui Cove in Port Ross at the northern end, and at Carnley Harbour at the southern end, of Auckland Island, and at Perseverance Harbour, Campbell Island. The stations were small, with four men at each. At first the coastwatchers were civilians, but all were attested as privates in the New Zealand Army from December 1942. The stations consisted of portable prefabricated huts with double plywood walls and double windows. Each station also had a dinghy with an outboard motor. Because it was understood that resupplying them could be problematic and sporadic, the stations were provided with three years' supply of food, clothing and other consumables. A larger vessel, the 57-ton MV Ranui with a crew of four, was based at Waterfall Inlet in the Aucklands to serve as a link between the stations and, in an emergency, the outside world.
Coastwatching
Early instructions to the coastwatchers emphasised concealment, with emergency radios set up in the scrub near each station. As well as their primary task of keeping their eyes on the sea for ships, the men carried out surveys, took weather measurements, and made observations on the wildlife of the islands. Each station made radio contact daily with New Zealand, at staggered times to minimise the risk of their presence becoming known. The men were relieved yearly, though a few repeated their tours of duty; two of them spent three years on the islands, with the naturalist J.H. Sorensen spending four years on Campbell Island. A popular recreational activity, which also supplied fresh meat to supplement the preserved food rations, was hunting the introduced species of wildlife on the islands. On Auckland Island there were wild pigs and, on Enderby Island, wild cattle and blue rabbits. On Campbell Island the feral sheep provided high qualitylamb and mutton.
Results
Although no enemy ships were sighted during the duration of the program, the secondary work carried out by the coastwatchers proved successful. From June 1942 the stations began reporting weather conditions daily; the reports were so valuable that in the third year of the program trained meteorologists joined the relief parties. Surveyors, geologists and naturalists also became part of the program, during the fourth and fifth years of which a special party of three completed the survey of the island groups. When the coastwatchers were demobilised on 15 October 1945 and withdrawn, the Campbell Island station was retained as part of New Zealand's weather forecasting service. Many of the scientific results garnered through the work of the Cape Expedition's coastwatchers were later published by the New Zealand Department of Scientific and Industrial Research in its Cape Expedition Series of bulletins. Ornithologist and museum directorRobert Falla had been involved in organising the expedition.
