Brooking said "rapid and efficient" contact tracing is one of the most important tools to find and stamp out Covid-19 from the region.
"Please turn on Bluetooth in the NZ Covid Tracer app and scan QR codes wherever you go. You will receive instant notifications about possible exposure to COVID-19," she said.
"Also, you should wash and dry your hands often, and cough and sneeze into elbows.
"Stay home if you're unwell and get advice on whether you need a test from your GP or Healthline.
"If you are told to get a test, do so immediately and isolate yourself until you receive your result."
Graham said the forum, which represents the HBDHB, local councils, emergency services, iwi and government departments, is working collaboratively.
"The Regional Leadership forum has been supporting and guiding Covid-19 resurgence planning, to make sure we are fully prepared if there was to be a community outbreak here," he said.
The Hawke's Bay Civil Defence Emergency Management Group also cited "rumours and misinformation", urging the public to only share information from official sources including The Unite Against COVID-19 and Ministry of Health websites, as well as the Hawke's Bay District Health Board.
