A teacher who was stabbed in the back in a classroom at Avondale College, is still in hospital.
David Warren, 49, was due to be released from hospital on Tuesday night.
However, the Auckland District Health Board says he remains a patient due to a separate medical problem, which cannot be disclosed for privacy reasons.
Mr Warren has thanked people for the support he has received since the attack.
A Korean student, 17, is due to appear in the Auckland District Court on Wednesday, charged over the stabbing.
