Auditors know exactly where to look. They walk in, grab your relief roster, and cross-reference it against your safety-check register. Any name missing from the register is an immediate breach. The documentation for relief staff is almost always the weakest in the workforce—fragmented between HR, booking systems, and payroll. That fragmentation is a gift to any compliance officer.

The Audit Trigger

The method is brutally simple. Auditors compare timetables or payroll records with your safety-check register. A reliever who worked Tuesday but has no file? Breach. A file that contains only a police vet from an agency but no interview notes, no identity check, no risk assessment? Incomplete check—still a breach. The Licensing Criteria for Centre-Based ECE Services 2008 (GMA106) is explicit: a full safety check requires identity verification, work history, professional organisation checks, an interview, referee information, a police vet, and a final risk assessment. Missing one component means the check has not been completed.

Even when an agency does the heavy lifting, the school must confirm every component meets the standard and then conduct its own identity check and risk assessment. Schools that rely solely on agency assurances without maintaining local records are caught cold when auditors ask for evidence of independent verification.

And the three-year re-check cycle? That is another trap. Relievers work irregularly, so schools often let re-check dates slide. Auditors start with the casual workforce when checking dates because expired checks show up there first.

The Regulatory Hook

This is not a grey area. The Children’s Act 2014 safety-checking regime applies to all “children’s workers,” and Ministry of Education guidance explicitly states that relief teachers are core children’s workers—they have regular contact with children without a parent present. The Education and Training Act 2020 and the Health and Safety at Work Act 2015 are also directly engaged. GMA106 makes it an offence to employ a children’s worker without completing a full safety check before they start work, and an offence not to re-check every three years. Serious non-compliance can be referred to Police for criminal investigation, with fines of up to $10,000 per person not safety checked.

The emergency exception—up to five consecutive working days with a current Police vet—is narrow and easily abused. Auditors examine patterns of “emergency” relief to see if schools are using it routinely for convenience rather than genuine, unexpected situations that increase risk to any child. Repeated use of the same reliever beyond five days is a red flag.

Beyond safety checks, induction and information access are separate compliance triggers. The Education Review Office (ERO) talks to staff. When relievers cannot describe child-protection policies, emergency procedures, or behaviour-management expectations, that signals inadequate induction. The Health and Safety at Work Act 2015 requires schools as PCBUs to train and supervise workers. Incident or near-miss reports involving relievers who were not briefed on hazard controls or emergency responses give auditors concrete evidence of systemic failure.

Teaching Council certification adds another layer. A current practising certificate means the police vet component is covered, but the other safety-check elements must still be completed and documented. If a certificate lapses, the teacher cannot continue as a children’s worker until either the certificate is renewed or the employer obtains a fresh Police vet and updated risk assessment. Auditors check certification expiry dates as a matter of course.
