This guidance provides an update on the use of Bluetooth tracing functionality in the NZ COVID Tracer app and provides information for health professionals regarding the management of individuals who receive a close contact notification following exposure to a case of COVID-19.
The use of Bluetooth functionality allows us to provide timely information to those that may have been in contact with COVID-19 and ensure they promptly self-isolate to reduce the risk of onwards transmission.
Bluetooth exposure notifications can be disseminated rapidly in comparison to manual contact tracing processes, and could also potentially notify close contacts that are not known to the case such as someone that travelled on public transport or attended a festival who was in close proximity to the case.
It's important to note that Bluetooth exposure notifications do not include any location or personal data so it will not be possible to definitively state where or with whom the exposure occurred. It will provide a date that the last exposure occurred, which is needed to calculate quarantine dates.
