In New Zealand, Christianity is the dominant religion with just under half (48 percent) of the population at the 2013 New Zealand Census declaring an affiliation to. Around six percent of the population affiliate with non-Christian religions, with Hinduism being the largest at over two percent, while 42 percent of New Zealanders are irreligious. New Zealand has no established church although Anglicanism is required to be the religion of the Monarch of New Zealand (who is described as "Defender of The Faith") and freedom of religion has been protected since the signing of the Treaty of Waitangi.
