What power would allow Ministers to close down a community?

The Herald reports:

Senior Government minister Louise Upston visited Gloriavale in late January, months after refusing to rule out closing the religious community following allegations of child abuse in the community.

Newstalk ZB has confirmed Upston visited the sect on January 30, alongside officials from the Ministry of Social Development.

This story is puzzling. As far as I know a Cabinet Minister can’t close down a religious community. The Government can close schools etc, but if a group of people choose to live together, and follow a religion together, that is not something a Minister needs to approve.
