Established in 1876 and 1890 at Cable Bay, north of Nelson, Trans-Tasman Telegraph Cable Numbers 1 and 2 were essential submarine telecommunication links between the extremity and heart of the British Empire.
An internal telegraph network begun in the 1860s helped link New Zealand together and enhance governance. Soon, attention turned to connecting on an international level across the Tasman Sea to Australia and then onto Britain. After protracted negotiations the Eastern Extension, Australasia and China Telegraph Company were contracted to establish and operate the first trans-Tasman telegraph cable in 1875. Trans-Tasman Telegraph Cable Number 1 was manufactured and installed by British company Telcon from the La Perouse, New South Wales, Australia end in February 1876 and was connected to the cable station established at Schroder’s Mistake (quickly renamed Cable Bay).
By the 1890s demand had grown for cable services and Eastern Extension installed a second cable. The relative isolation contributed to the cable station burning down in 1914, motivating the company to relocate the cables to Titahi Bay, near Wellington, in 1917. Another incentive was that most of the telegraph traffic was destined for Wellington and the North Island, which had now surpassed the South Island as the main population base.
In turn, in 1932 a composite of Cable Numbers 1 and 2 was relocated to Muriwai Beach, west of Auckland, making the beach the landing point for all the submarine communication cables connecting Sydney and Auckland. The Trans-Tasman Telegraph Cable was eventually abandoned in 1963 when the Commonwealth Pacific Cable (COMPAC), New Zealand’s first international telephone cable, was completed.
The remnants of Trans-Tasman Telegraph Cable Numbers 1 and 2 at three New Zealand landing sites have outstanding engineering heritage importance because the cables revolutionised the country’s communications. Trans-Tasman Telegraph Cable Numbers 1 and 2 were the country’s first and most efficient telecommunications link to the rest of the world, reducing New Zealand’s isolation. For several decades into the 20th century the cables enabled stronger international political, commercial, and social ties between New Zealand and Australia in particular.
Trans-Tasman Telegraph Cable Numbers 1 and 2 was added to the IPENZ Engineering Heritage Register on 26 August 2014.
