Tararua residents are being encouraged by MidCentral DHB to utilise the Covid Tracer app and check-in at all places they visit.
It is now mandatory for businesses to display a QR code for the NZ Covid Tracer app.
MidCentral DHB Medical Officer of Health Dr Robert Weir said it was important for people to track their movements to allow for easy contact tracing if the Covid-19 virus re-emerges in the community.
"The best way for us to quickly trace close contacts of any confirmed Covid-19 cases and break the chain of transmission is if people keep track of their movements," Dr Weir said.
"If everyone is using the NZ Covid Tracer app, our public health teams can easily and quickly let people know if they have had any risk of exposure directly through the app.
