The Ministry of Heath are encouraging people to download and use this app.  If COVID-19 re-emerges in the community, fast and effective contact tracing will be key to breaking the chain of transmission and minimising the risk or extent of any further lockdowns.  NZ COVID Tracer supports this by giving contact tracers a head-start and by allowing them to send contact alert to people who may have been exposed to the virus.
