This painting of a fortified pā around 1845 shows a potato field (top right). Potatoes began to be grown on a commercial scale soon after they were introduced, particularly in the far north, to supply whalers. Potatoes and pigs were such important trade items they served as a currency for a number of years in New Zealand.
