Following his return to Britain after the Palliser expedition, Hector again secured a paid scientific position with Roderick Murchison's and
Joseph Hooker's help. In April 1862 he arrived in
Dunedin in New Zealand to conduct a three-year geological survey of
Otago, soon after the discovery of gold there. Hector travelled throughout the south of New Zealand's
South Island to assess its potential for settlement and to record the location of useful minerals. He also assembled a staff of half a dozen men to assist with such tasks as fossil collecting, chemical analysis, and botanical and zoological taxonomy. Some of these men, such as
William Skey (mineral analyst), Richard Gore (clerk), and
John Buchanan (botanical artist and draftsman), stayed with him for many years. As part of the survey, a Geological Map of Otago was created, known as Hector's Map. In 1865 a "Sketch Map of the Geology of New Zealand" was produced, and in 1869 it was revised and published by the Government Printing Office in New Zealand; giving a synthesis of New Zealand geological research in the first geological map of the country.
Chief government scientist In 1865 Hector was appointed to found the
Geological Survey of New Zealand, and he moved to
Wellington to supervise the construction of the
Colonial Museum, which was to be the Survey's headquarters. As the chief government-employed scientist, Hector gave politicians advice on questions as diverse as exporting wool to Japan and improving fibre production from New Zealand flax. He was the first manager of the Wellington Botanic Gardens on their opening in 1869. He went on to develop the Gardens with the New Zealand Institute (now known as the Royal Society of New Zealand) for 22 years. His political influence was underlined by his marriage in 1868 to Maria Georgiana Monro, daughter of the
speaker of the
House of Representatives,
David Monro. Hector managed the colony's premier scientific society – the
New Zealand Institute (now known as the
Royal Society of New Zealand) – for thirty-five years. He was the first manager of the Wellington Botanic Gardens on their opening in 1869, developing the gardens with the New Zealand Institute for 22 years. From 1885 he was chancellor of the
University of New Zealand. He controlled virtually every aspect of state-funded science. He had close and, at times, tense relationships with other men of science, in particular
Julius von Haast in Christchurch; e.g. (1871–74) over the "Sumner Cave" relics in Christchurch, the Moa and whether the early Moa-hunters were
Moriori as Haast maintained. At the end of his career he was criticised for failing to acquire
Māori artefacts for the Colonial Museum and in 1891 for not adequately defending his departments from the new
Liberal Government's funding cuts. In 1891 the Liberals replaced the conservative
Continuous Ministry with which he had been associated. In 1902, for example, the ethnographer
Elsdon Best wrote to
Augustus Hamilton, the future director of the Colonial Museum, to state that Hector should be forced from office and that they should
put a live man in his place.
Retirement Hector retired in 1903, after four decades at the centre of organised science in New Zealand. He was president of the
Royal Society of New Zealand between 1906 and 1907; preceded by
Frederick Hutton and followed by
George Malcolm Thomson. He died in
Lower Hutt, New Zealand, in 1907, ==Family==
