A church is a building or a congregation of people, primarily associated with the Christian religion, where people gather for worship and religious activities. It can refer to the physical structure itself, the group of believers who regularly meet there, or the broader Christian institution.
A charity is a non-profit organization established for a charitable purpose, primarily to benefit the public. In New Zealand, to be considered a charity, an organization must have a purpose that provides a public benefit, must not operate for private profit or benefit, and must have sufficient rules in place to ensure it stays within its charitable purpose.
