New Zealand's official aid programme is managed by the New Zealand Agency for International Development (NZAID), a semi-autonomous body within the Ministry of Foreign Affairs and Trade. In 2007, New Zealand was the sixth lowest foreign aid donor in the Organisation for Economic Co-operation and Development (OECD), based on proportion of gross national income (GNI) spent on overseas development assistance. New Zealand's contribution was 0.27% of GNI. Much this went to the Pacific region. However, the country is occasionally more generous in responding to major crises, for example donating around $100 million to the 2004 Indian Ocean tsunami relief efforts, the committed $1 million to the 2010 Haiti earthquake relief efforts, and later the government donated $2 million to the 2011 Japan earthquake and tsunami relief efforts. Following the April and May 2015 Nepal earthquake, the New Zealand Government sent an initial $1 million in humanitarian aid, and has mobilized 45 urban search and rescue technicians. New Zealand troops and aircraft are also often sent to disaster areas in the Asia-Pacific region.
