The story of how the map of New Zealand emerged is a fascinating one. The first full map of the islands was published in London in 1773, which might seem the natural starting point, but over the preceding 150 years, fragments of charts and intelligence about New Zealand ricocheted around various parts of the world. In A Draught of the South Land, Paul Moon provides the first comprehensive account of this piecemeal process. Moon’s investigation covers several continents over more than a century, and reveals the personalities, blunders, strategic miscalculations, scientific brilliance, and imperial power-plays that were involved. Above all, he examines the roles played by explorers and traders, Māori and European rulers, scientific societies and military groups, as well as specialist cartographers and publishers. At a time when maps as colonial tools, enablers of trade and objects of curiosity are being studied anew, his careful analysis and engaging narrative will be of interest to scholars everywhere.
