I wonder if there is still a cable under the Hauraki Gulf performing this task? The photo is not very clear but it looks to be a Hughes 300?
From The Press, 15th of January 1970.
PRECAUTIONS FOR SAFETY OF SHIPPING.—The Defence Department has relaid magnetic detection equipment in the Hauraki Gu1f, 30 miles north of Auckland City. The equipment helps to keep ships safe from .magnetic mines and was first laid during the Second World War. A Ministry of Works team, instructed by senior officers of the Devonport Naval Base, used a helicopter to complete the work in 10 hours. The pilot lowered 12,800lb of sensing units, linked to armoured cable, to two divers in 85ft of water, who chained them to anchor points on the sea-bed. This photograph shows the helicopter taking an enormous “bite” out of the detecting equipment's cable to drag it to the on-shore station. The extent of ships' magnetic influence is monitored as they pass over the sensing units. The generating of electrical currents can attract and detonate magnetic mines.
