When “Proof” Crosses the Line
A restaurant chain overseas recently told staff they had to take a photo of themselves at the medical centre before their sick leave would be accepted — and banned the use of medical certificates issued after telephone or online consultations. The backlash was swift, and the policy was withdrawn.
It’s a good reminder for New Zealand employers: even well‑intentioned HR rules can cross into unlawful territory.
Under NZ employment law:
• You can ask for proof of sickness — but it must be reasonable and lawful
• You can’t demand photos or other privacy‑invasive evidence
• Medical certificates issued after telephone/online consultations are valid
• Policies must be applied in good faith and respect employee privacy
If you want to reduce sick leave misuse, start with culture, not control. Early upfront conversations go further than surveillance ever will!
