In 2016, all people who answered the religion question on the Tokelauan census gave one of the major Christian denominations as their religion- Congregational Christian Church (Ekalehia Fakalapotopotoga Kelihiano Tokelau) and Roman Catholic.
In 2016, the majority of Tokelau’s usually resident population on Atafu (78.3%) and Fakaofo (62.7%) identified as Congregational Christians.
While this denomination has remained the largest on both islands, the proportion of residents identifying with it has declined.
Roman Catholicism has remained the dominant denomination among Nukunonu residents.
In 2011, 93.9% of the usual residents were Roman Catholics, a slight decrease from 96.9% in 2006.
