In March 1946, the School became a civil institution, named The Australian School of Pacific Administration, and was transferred to Georges Heights, Mosman, NSW, and later to Middle Head. ASOPA was given statuatory recognition under the Papua New Guinea Act in 1949 and continued to function as a responsibility of the Minister for External Territories till 1 December 1973, when the International Training Institute (ITI) came into existence as a result of the Australian Government’s decision to integrate ASOPA into the structure of the Australian Development Assistance Agency (later AIDAB), under the Minister of Foreign Affairs. ITI closed in 1997.

Paton Memorial Hospital was formally opened on 14 January 1911, located on Iririki island just off Port Vila, on Efate, Vanuatu (then New Hebrides). The hospital closed after Vila Central Hospital was opened in 1975.

The Foreign Missions Committee was established by the "Southern Church" of the Presbyterian Church in New Zealand. The Southern Church was represented by the Presbyterian Synod of Otago and Southland and was based on the Free Church of Scotland ideals.
The Foreign Mission Committee was elected to take charge of missionary activities for the "Southern Church" of the Presbyterian Church in New Zealand. This included administering all foreign mission appointments and matters and organising an annual mission collection to support missionaries in the field.

The Teachers Training Institute, later Tangoa Training Institute, was located on Tangoa, a small island off the coast of Santo, Vanuatu. Established by the Presbyterian church mission to the New Hebrides, it was established by synod in 1887 and officially opened in March 1895. It's first principal was missionary Reverend Joseph Annand from Canada, followed by Reverend Frederick G Bowie, who was principal until his death in 1933. At the institution, young men and, later, women from different islands in Vanuatu were trained in the Bible and taught technical skills, which, in the early decades at least, largely involved plantation work for the mission.

The Diocese of Kavieng encompasses the two provinces of Manus and New Ireland. Out of a total population of 96,000 about 45,000 are Catholic. Missionaries of the Sacred Heart (MSC) arrived in New Britain in 1882. By the turn of the century, evangelisation had begun in New Ireland, and ten years later the first missionary priests reached Manus. In both cases, Catechists preceded the missionaries. By 1935 parishes had been founded throughout the two major islands of Manus and New Ireland and on most of the larger adjacent islands.

During World War II/WWII the Vicariate of Rabaul lost over 40 priests and 40 brothers, and most buildings in many parishes were destroyed. After the War came a new influx of missionaries from the German, Irish, and American provinces of the MSC. Schools, churches, convents and health centres were quickly rebuilt from scrap materials salvaged from installations left by the American forces. At the same time, the mission made a strong commitment to education and began training large numbers of local teachers.

In 1957 Kavieng was separated from Rabaul and made a Vicariate under Bishop Alfred Stemper, MSC. In 1966 Kavieng and other Vicariates were made Dioceses, and more conscious attention was given to the development of the local church. The first two national priests from Kavieng Diocese were ordained in 1968.

Bishop Stemper retired in 1981, handing over the Diocese to the care of Bishop Hesse. Bishop Stemper died in Kavieng on 20 February 1984.
Transportation and communication remain the main difficulties due to the size of the Diocese (136kms square).

The LMS Samoa District was the London Missionary Society mission church in Samoa. The governing body was made up of the European missionaries in Samoa. Throughout the 19th Century the LMS Samoa District evangelised Niue, Tuvalu, and the South of Kiribati (which was known as the Northwest Outstation). The missions and emerging churches in Niue, Tuvalu and South Kiribati were under the control and administration of the Samoa District Committee. Samoan missionaries looked after the churches in Niue and Tuvalu under the supervision of European LMS missionaries.
