Fair trade in New Zealand: Fair trade is where a farmer or craftsperson is paid a fair price for their product, one that represents its true worth, not just the lowest price that it is possible to pay.  This is a price that covers the cost of production and provides the producer to live with dignity.  Fair Trade New Zealand is an organisation that was launched in 2005 which supports fair trade by ensuring that farmers and workers' rights are not exploited.  According to Oxfam New Zealand, there are several companies to support fairly traded goods from, which are exported to New Zealand.  From 2013-2014 there were 42 Fair Trade Licensees and Traders in New Zealand.  From 2015-2016 this number rose to 54 Fair trade Licensees and Traders in New Zealand.  Gwen Gwenn, Oxfam's Engagement Director, says: “when farmers are paid fairly for their products, we see people able to make real improvements to their lives and their communities.  Producers who used to struggle to feed their families are able to give their children an education, and communities can build schools and develop businesses.  It is one of the smart solutions to poverty”.  In 2009, Wellington became the first fair trade capital city in the Southern Hemisphere.  In 2017, Whangarei was recognised by the Fair Trade Association of Australia New Zealand as being one of four fair trade councils in New Zealand, and the first fair trade district in New Zealand.
