The Kohanga Reo National Trust says its students who gained an unrecognised qualification will in the meantime receive a kohanga approved tohu (certificate).
An audit earlier this year discovered it had students enrolled in a course, Te Takaimatua, which had not received approval or accreditation by the New Zealand Qualifications Authority.
It left the trust out of pocket by nearly $800,000 after having to repay funding it gained from the Tertiary Education Commission for the course.
The trust's co-chair, Tina Olsen-Ratana, says it has informed kohanga that those who did complete the Takaimatua programme will get a tohu from the trust.
She says the trust has completed the first step towards getting accreditation for the programme, so once that happens, it will reassess students and hopefully give them the accredited qualification.
