The Quakers not only played a leading role in the anti-slavery movement - they founded many of Britain's best known companies. The Seventh Day Adventist church founded, and still owns, New Zealand's most successful cereal manufacturer - Sanitarium, and many of New Zealand's early business elite were devoutly religious. Jeremy Rose talks to Sanitarium general manager Pierre van Heerden and James Walvin, author of 'The Quakers: Money and Morals'; then Chris Laidlaw talks to historian and author Ian Hunter about the influence of religion on the history of business and the economy in New Zealand.
