The Christian Brethren Church of New Zealand is the name by which churches in the Open Brethren movement in New Zealand are publicly known. It is not a denomination in the organizational sense, but a loose network of like-minded autonomous local churches, or "assemblies", as Brethren churches are generally known. According to the Evangelical publication, Operation World, there are 202 Brethren congregations in New Zealand with 16,164 in regular attendance (including children). Some Brethren sources claim this number to be an underestimate, with internal surveys indicating as many as 38,000 adults and children attending Brethren assemblies — almost one percent of New Zealand's population.
