G. B. Fisher in New Zealand, and became widely known through the publication of his book, The Clash of Progress and Security, in 1935. It took its origin from the titles current in Australia and New Zealand of 'primary industry' for agriculture, grazing, trapping, forestry, fishing and mining, and 'secondary industry' for manufacture. In Australia and New Zealand these terms are not only used in statistical reference books but are widely current in popular discussion. The phrase 'tertiary industries' therefore immediately carries, in these countries, a suggestion of those excluded by the official definition of 'secondary industries."}} {{-}}Sakesektore2. ^{{cite web| url =http://geography.about.com/od/urbaneconomicgeography/a/sectorseconomy.htm | title=Sectors of the Economy | author=Matt Rosenberg | date=14 January 2007 | publisher =About.com | accessdate=20 April 2012}} 1 : Economic sectors |
