English: showing trends in religious affiliation (or non-affiliation) in New Zealand according to the 1991-2006 Censuses. "Maori Christian" is included within the "Christian" total. The "Other" figure was derived by subtracting all the other figures from the total number of people with valid responses. This avoids double counting people with more than one "Other" religion, but excludes "Christian" people with another religion from the "Other" total. In 1991 and 1996, only a single religion was recorded for each person, so this problem does not affect those years.
