New Zealand’s Data Breach Response Plan: A Guide to Effective Management

In the event of a privacy incident or breach, having a tested response plan in place is crucial for minimizing harm and ensuring compliance with legal requirements. The Office of the Privacy Commissioner (OPC) provides guidance on how to respond to privacy breaches, and it is essential that agencies have a comprehensive plan to deal with such incidents.

NotifyUs: An Online Tool for Determining Breach Notification

NotifyUs, an online tool provided by the OPC, can help determine whether a breach requires notification and reporting. If an agency has a privacy breach likely to cause serious harm, it must notify the OPC and affected individuals as soon as practicable.

Creating an Incident Response Plan

A well-crafted incident response plan should provide clear instructions on how to respond to a privacy incident effectively and in a timely manner. It should be concise, accessible, and flexible enough to be applied to different incidents. The plan should also be reviewed and approved by the senior leadership team to ensure effective leadership and governance.

Key Components of an Incident Response Plan

• Roles and Responsibilities: Clear roles and responsibilities are essential for effective incident response. This includes designating who will:
  • Assess whether a breach reaches the level of serious harm
  • Notify affected individuals or the OPC
  • Input information into NotifyUs
• Communication Tree: A communication tree is a useful tool for gathering and collating contact information for key individuals involved in incident response, staff, third-party providers, and government agencies.
• Containment and Assessment: The plan should include clear instructions on how to:
  • Contain the breach immediately
  • Assess its severity
• Risk Evaluation: The plan should evaluate the risks associated with the breach, considering factors such as:
  • The type of personal information involved
  • Potential harms
  • The likelihood of each risk occurring
• Notification: The plan should outline a process for determining whether notification is necessary and include guidelines on how to:
  • Notify affected individuals or the OPC
• Prevention of Repeats: Following a privacy breach, the agency should:
  • Investigate its cause
  • Update processes and practices as needed to prevent similar incidents from happening in the future

Best Practices for Data Breach Response

• Be open and transparent with individuals about how their personal information is being handled • Consider each incident on a case-by-case basis whether to notify affected individuals or not • Account for mandatory breach notification provisions included in the Privacy Act • Provide a process for engaging with third parties, such as Police and insurers • Include a communications plan that includes managing media and public enquiries

By following these guidelines and best practices, New Zealand agencies can ensure effective management of data breaches and minimize harm to individuals.
