Leavers' trust manager Liz Gregory said the Employment Court evidence warranted another investigation.
"There was so much undisputed evidence in the employment hearing that Charities Services must be concerned," she said.
"I think it's a no-brainer. I don't think they match up to what New Zealanders would expect the charitable sector to look like and behave like. We do not believe they meet the standards of charities in New Zealand."
In February, the Employment Court heard evidence about working conditions at Gloriavale, in a case brought by three leavers seeking a declaration they were employees, not volunteers.
Last year the Labour Inspectorate said it could not investigate alleged employment law breaches at Gloriavale because its members could not legally be considered employees.
Chief judge Christina Inglis has reserved her decision.
Six women who are former Gloriavale members have also won the right to have their case heard in court later this year.
'Allegations of massive misconduct'
In a letter to Charities Services, Gregory said the "emerging evidence" validated leavers' concerns.
"Delays in appropriate outcomes from various agencies to date have resulted in untold sexual harm, violence, coercion, manipulation and exploitation of labour over this time," she said.
"A number of agencies have re-evaluated their position over recent years, and we ask that the Charities Services looks again at the allegations of massive misconduct."
More than 75 people had left Gloriavale over the past 18 months, Gregory said.
Charities Services general manager Mike Stone confirmed the agency had received the request for another investigation.
"We are presently assessing that request and expect to make a decision shortly and will then convey that to the trust," he said in a statement.
Records show the Christian Church Community Trust has eight companies and reported revenue of $20 million.
