The authority's audit looked at 366 of 436 reported results from 25 students last year. It found the grades awarded were not all at the national standard for 105 of the marked results (28.7 per cent). In almost all cases, the school's "achieved grade" was lowered to "not achieved".
Other concerns identified included:
-NZQA said students had access to exemplar material, and the same exemplars without any change were used to assess the students.
-More sophisticated student work being generated followed by more simplistic and error-prone work.
-Some work was word-for-word identical to text on Wikipedia.
-Some work was written by another person, later identified as another student.
Ms Parata said she was "extremely disappointed to hear about the powhiri" as the students' "education and futures are at stake".
"I really feel for the learners but the truth of the matter is Moerewa School has let these students and their whanau down.
"As the NZQA audit found, work was copied from Wikipedia, exemplars were not altered and some of the work was completed by other students.
"That will not be tolerated from any school. Our learners deserve better."
Ms Milne-Ihimaera said the school did not condone copying from Wikipedia but the concern related to a small amount of work. She maintained staff could have turned the situation around quickly but were not given the opportunity.
"We've had no opportunity to work with NZQA or work with the ministry. You can't get too much more of a sledgehammer than those two."
A community meeting to discuss other options for the senior students is scheduled for 6pm today at the school.
Ms Milne-Ihimaera accepted that the satellite arrangement was at an end. Asked if students would be taught from tomorrow, she said: "I'm not sure what will happen on Tuesday yet, we're still working out some solutions within our community."
