The islands presently known as the Cook Islands was briefly visited by missionaries on a few occasions in the mid to late 1800's. Missionaries arrived in 1899 but left by 1903 due to lack of interest in the church. In 1942, Fritz and Maudina Kruger, a newly married couple, was assigned to establish the church in Rarotonga. They established a bakery business in Avarua. On May 12, 1942, the Cook Islands first converts, Samuel Glassie and his family, was baptized. In 1943, church meetings were held in the northern Puaikura District. Later that year Sunday meetings was relocated to Muri. By June 1946, there were 37 members. Around this time, Kruger and his family returned to New Zealand, briefly leaving no priesthood leadership.Trevor and Mildred Hamon arrived on September 12, 1946 with instructions to build a chapel. On October 6, 1946 a branch was organized. Early meetinghouses were mostly native hut-like structures. More permanent structures were built starting in 1955. On January 17, 1955, church president David O. McKay visited with members in Rarotonga. The Book of Mormon was translated into Cook Islands Maori in 1966.
