Corruption is defined as the abuse of public office for private gain. Often, corruption has devastating consequences, the two main consequences of which are economic and social. Unfortunately corruption exists most in developing countries, where people already live under hard economical and social conditions. The Pacific Islands are a region where corruption is a problem. Some countries are doing better than others, some have improved and some have got worse. But almost all of the Pacific island countries have faced cups or riots, breakdown of law and order as a consequence of corruption. The region is unique and characterized by ecological and cultural diversity, colonization, tribes, a human history rich in epic ritual, travel, narrative, and innovation. This thesis has examined one small Pacific Island country, Vanuatu which is a typical example of an island country in the region. 76 % of the people lives on 83 different islands and have little contact with the central island and its public and political administration. The purpose was to examine why corruption exists in the region with the help of different corruption theories. The result was that many Islands in the Pacific have been colonised and have had very little time to build up a stable public and political administration. Results also showed that the islands have a strong tribal tradition and people lives isolated on islands far away from the “real political life”, there is also a culture which accepts e.g. bribery and the general attitude is that parliamentarians should look after their original tribe rather than the entire country.
