New Zealand and the European Union are working together on a development mission to four Pacific nations.
Foreign Minister Murray McCully and the European Commissioner for International Co-operation and Development, Neven Mimica, are leading it.
They're leaving today to visit Papua New Guinea, Vanuatu, Kiribati and Tuvalu.
"New Zealand and the European Union work together closely in the Pacific, particularly in support of renewable energy initiatives," Mr McCully said.
"This mission is an opportunity to take stock of progress across the region and look for new areas of co-operation."
