As much of his early life, Hartley's life during the California gold rush is equally poorly recorded. What is known is that both Hatley and Reilly followed the gold rush from California to the
Victorian goldfields in
Australia. Departing Victoria and travelling from
Sydney to
Auckland, the pair arrived in
New Zealand in 1862. Hartley and Reilly worked the sides of the
Cromwell Gorge for three months until they were forced to take the huge hoard of gold they had secretly amassed to the Chief Gold Receiver in
Dunedin in August 1862. Hartley and Reilly's discovery caused great excitement as they deposited some 87 lb (1,044 t oz) of gold, sparking a gold rush to what would become known as
Hartley's Beach. Hartley and Reilly, in divulging the location of their rich finds (approximately one mile downstream of the confluence with the
Kawarau River), were rewarded with £2000 from the Otago Provincial Government. On 23 September 1862 the Dunstan goldfield was proclaimed, the selection of this name in preference to Hartley's being largely in deference to Reilly, who was 'jealous of the pre-eminence' accorded Hartley as the discoverer. Hartley assessed (and purchased into several claims) in the Coromandel goldfields on behalf of
Otago miners, expressing that he had never seen anything better in quartz countries. On reaching the
Awarau River, he was forced to turn back due to a shortage of provisions. ==Later life==
