Northland teacher James Parker was able to continue his offending against young boys partly because of his close relationship with his principal and his role as deputy principal and kapa haka leader, a report has found.
Parker, the former deputy principal of Pamapuria School, 10km south of Kaitaia, is awaiting sentence on 49 sexual abuse charges.
He was due to be sentenced next Thursday, but that is likely to be delayed due to fresh complaints since his crimes became public.
An independent report, released yesterday, aimed to find out why the school failed to keep its children safe and what could be done to prevent other cases. It is separate from the ongoing police investigation.
It found warning flags had been raised several times since Parker started teaching at Oturu School in Kaitaia in 1998, including about his habit of showering with boys staying at his home or sharing a bed with them "marae-style".
