Giant placer gold fields are present in Cenozoic gravel and sand in Westland and Otago-Southland, and smaller placers are found in west Nelson and Marlbor-ough (Figure 1; Christie 2016). The West Coast placers also extend offshore (Youngson and Stevenson 2016). Mining of the onshore placer gold deposits has been an important contributor to New Zealand's economy, especially in the early gold rushes of the 1860s-1870s that resulted in a substantial increase in the European population, a diversity of culture and the development of industry. New Zealand's total production from the 1850s to present day is c. 20 million oz of gold and the current annual production is c. 34,000 oz of gold with c. 90% from the West Coast. New Zealand has been a World-leader in many aspects of placer gold mining and processing technology, and geological research.
