Can my employer monitor my emails and computer activity in NZ?

In New Zealand, employers can monitor work email and computer activity, but there are important restrictions.

What the law requires:

Written policy (Privacy Act 2020, IPP3): Employers must tell employees that monitoring may occur and for what purpose. Monitoring without disclosure is likely a breach of the Privacy Act.

Good faith obligation (ERA 2000, s4): The Employment Relations Act requires employers to be open, honest, and communicative. Secret monitoring that is later used in disciplinary action may be challenged as a breach of good faith.

Personal use on work devices: If employees are permitted to make limited personal use of work devices (or if personal use is tolerated in practice), courts have found that employees retain some reasonable expectation of privacy even on work equipment.

What employers generally CAN do:

• Monitor work email for business purposes (with a disclosed policy)
• Access work systems to investigate genuine misconduct
• Log system activity on employer-owned devices

What employers generally CANNOT do:

• Monitor personal email or personal accounts (even on work devices) without strong justification
• Use surveillance data for reasons unconnected to the original monitoring purpose
• Conduct covert surveillance without specific legal authority

Best practice for employees: Do not use work devices or accounts for personal communications you want to remain private.
