traditionally had a strongly decentralised organisation, designed to allow electorates and the five regions to appeal to the unique voter base in their area. However, in light of the 2002 election result, in which the party suffered a significant loss of its support base, a review of the party organisation resulted in decisions to weaken the regional structure and to implement a more centralised structure. The restructuring was ostensibly planned to make the party organisation more "appropriate" for the mixed-member proportional electoral system, where votes are cast for a countrywide party list. Currently, the affairs of the party are centrally governed by a Board of Directors, comprising the party leader, one caucus representative, the party's general manager and seven elected members. The board elects a party president from within its members. An Annual Conference determines party policy, and elects members to the Board of Directors. The party is subdivided into Electorate Committees; each committee sends six delegates to Annual Conference, including a chair and any MPs from within the electorate. The leader of the National Party ( Christopher Luxon), elected by the party's current sitting MPs, acts as a spokesperson for National and is responsible for managing the party's business within parliament. The president ( Sylvia Wood, elected to the role in August 2022) heads the administration outside of parliament. Within National there are a number of organised groups of members, called Special Interest Groups, that share a particular belief, interest or cause. Other groups are also involved in the party's policy reviews. For instance, the Bluegreens are a group within National who help formulate environmental policy. The party's youth wing, the Young Nationals (commonly known as the Young Nats), has provided much political impetus as a ginger group. Often the more social-liberal views of the Young Nats have been at odds with those in the senior party. National is affiliated to—and plays a leading part in—the International Democrat Union (IDU) and the Asia Pacific Democrat Union (APDU). Former National Prime Minister John Key was the chairman of the IDU from 2014 to 2018.
