The Pacific Islands Province was formed in 1981 when the former Pacific Province split into two halves. The southern half (Australia and New Zealand) took the name of Australia / New Zealand Province, while the northern half (Papua New Guinea and Solomon Islands) was named Pacific Islands Province.
This province split further in 2008 into the Papua New Guinea Province and the Province of the Solomon Islands.
