Accredited Employers Programme (AEP) - ACC Tina, I work for an organisation that is an accredited partner. Firstly, it is designed for large organisations - as a thumb rule, say with a workforce of over 400 or so. Secondly, if you want to become one just to pass the audit and to get some discount on the ACC levies, forget it. That should not be the motive. The audit is WSMP + Injury Management, so the audit is not too dissimilar to WSMP audit.
