Passage: Christianity is the predominant religion in New Zealand, although its society is among the most secular in the world. In the 2013 census, 55.0% of the population identified with one or more religions, including 49.0% identifying as Christians. Another 41.9% indicated that they had no religion. The main Christian denominations are, by number of adherents, Roman Catholicism (12.6%), Anglicanism (11.8%), Presbyterianism (8.5%) and "Christian not further defined" (i.e. people identifying as Christian but not stating the denomination, 5.5%). The Māori-based Ringatū and Rātana religions (1.4%) are also Christian in origin. Immigration and demographic change in recent decades has contributed to the growth of minority religions, such as Hinduism (2.1%), Buddhism (1.5%), Islam (1.2%) and Sikhism (0.5%). The Auckland Region exhibited the greatest religious diversity.
