New Zealand and Chile are engaging in a strategic partnership in geothermal energy, according to several sources. The New Zealand Embassy in Santiago, Chile offers a Joint Statement from Prime Minister Rt Hon John Key and the Chilean President, Sebastian Piñera, issued in March 2013 from Chile. The purpose of the statement was to set out the framework for the relationship between the two countries, which are also linked by the Trans-Pacific Strategic Economic Partnership Agreement (TPP) signed in 2005 between Brunei Darussalam, Chile, New Zealand and Singapore.
