We are committed to complying with the 'notifiable data breach' scheme (the NDB Scheme) in Australia and the privacy breach notification regime in New Zealand (as may apply under the relevant Privacy Act).
In Australia, a data breach is notifiable to the Office of the Australian Information Commissioner (OAIC) when an 'eligible data breach' occurs which is when:
In New Zealand, a 'notifiable privacy breach' means a privacy breach that it is reasonable to believe has caused serious harm to an affected individual or individuals or is likely to do so. The assessment of whether serious harm has occurred, or is likely to occur, considers factors such as measures to contain the information, the nature of the harm that may be caused, whether the personal information is sensitive in nature and whether any unintended recipient of that information may cause harm to the person that the information is about. Types of serious harm include:
An organisation may take remedial steps to prevent the likelihood of serious harm occurring for any affected individuals after a data breach has occurred. In which case, the data breach is not an 'eligible data breach'.
Where we have reasonable grounds to believe that we have experienced an eligible data breach (and remedial action cannot be used), we will notify affected individuals and the OAIC about the breach in accordance with the Privacy Act.
Where you upload information via our Platform, by the very act of your upload you consent to us keeping your Personal Information for the purposes of dealing with your inquiries and our supply of goods and services to you.
