“Originally settled by Polynesian emigrants from surrounding island groups, the Tokelau Islands were made a British protectorate in 1889. They were transferred to New Zealand administration in 1925. Referenda held in 2006 and 2007 to change the status of the islands from that of a New Zealand territory to one of free association with New Zealand did not meet the needed threshold for approval.”
CIA's The World Factbook (2013)5
As a territory of New Zealand I do not have many specific statistics for this territory in its own right.
Data from the Pew Forum, a professional polling outfit, states that in 2010 the religious makeup of this country was as follows in the table below6:
The CIA World Factbook has slightly different data, and states: Congregational Christian Church 70%, Roman Catholic 28%, other 2%. note: on Atafu, all Congregational Christian Church of Samoa; on Nukunonu, all Roman Catholic; on Fakaofo, both denominations, with the Congregational Christian Church predominant7.
There isn't much information in the database for Tokelau, most likely because it is either a part of another country (i.e., a territory or posession) and therefore most international statistics are counted for the country as a whole, or, this is such an exotic place that little data exists about it.
