The Western Pacific Region, one of the six regions of the World Health Organization, is home to approximately 1.6 billion people, nearly one-third of the world's population.

It stretches over a vast area, from China in the north and west, to New Zealand in the south, and French Polynesia in the east. One of the most diverse of the WHO regions, the Western Pacific constitutes some of the world's least developed countries as well as the most rapidly emerging economies.

The WHO Representative Office in the South Pacific provides technical support to many Pacific island countries and areas, including Fiji, French Polynesia, Kiribati, Mariana Islands (Northern), Marshall Islands, Federated States of Micronesia (FSM), New Caledonia, New Zealand, Nauru, Palau, Solomon Islands, Tonga, Tuvalu, Vanuatu, and Wallis & Futuna.

Main focuses include combating communicable diseases, building healthy communities and populations, the health sector development, and 'reaching out' (IT, external relations and public information).
