However, the NCEA marks do not seem to have made much difference to schools' overall academic rankings compared with previous years.
The girls' schools to reach the 10 are St Cuthbert's, Diocesan, Rangi Ruru, Samuel Marsden, Chilton St James, Columba College, and St Oran's. Only two state schools feature: Cambridge High and Auckland Grammar, the only boys' school among the 10.
A private co-ed school, the Senior College of New Zealand in Auckland, made it to sixth place despite not having entered students into NCEA.
St Cuthbert's principal, Lynda Reid, put her school's success down to quality of teaching, enthusiastic students and a culture of innovation and willingness to change.
She did not think it was fair to compare her girls and students at a state school in a poorer area, with fewer resources and lower expectations from parents.
"In the end I'm not going to apologise about the success of our kids. I'm really proud of all of them," she said.
But Otahuhu College principal Brian O'Connell said St Cuthbert's and other private schools had a head start because they could pick from the best students.
