A nearby resident of Gloriavale told the Greymouth Star newspaper they had been informed of the Covid-19 outbreak.
"They're just good neighbours, they let us know they had Covid, that they were isolating and asked us to keep our distance," the resident said.
When approached by the Herald for comment, Gloriavale was tight-lipped.
"We're not interested in speaking with the press," a member said.
In a response to Herald inquiries about the Gloriavale outbreak, a Ministry of Health spokesman said: "We are aware of many exposure events related to faith-based gatherings but do not comment on individual ones due to privacy, unless there is significant and widespread risk to community public health."
Gloriavale had been slow to get the Covid-19 jab, with vaccinations not being part of their belief system.
But when the Government introduced vaccine mandates for the education and health sector late last year, threatening to close Gloriavale's on-site schools, costing them funding, it appears senior leadership had a change of heart.
Gloriavale's teachers and midwives later accepted their Covid vaccinations.

Last week, medical and virus experts said they feared the true extent of the Omicron strain's spread in New Zealand might not be known because some Covid-19 positive people weren't recording their test results.
"If you test positive with a rapid antigen test, it's essential you register your positive result," the ministry said.
A strain on the health system is beginning to show, according to doctors around the country.
At Waitematā DHB, the entire legal team had been redeployed to support security guards, anaesthetists at Auckland Hospital were working as phlebotomists and taking blood, while members of the executive leadership team were working in the emergency department, making beds, answering calls and clearing linen skips.
Regional chairman of the Australia and New Zealand Intensive Care Society Dr Craig Carr said the demand on intensive care was a real challenge, but teams were holding up reasonably well.
