HUNTER exposure sites have grown again, with more than half a dozen additions and amendments to the region's risk list overnight.
Testing capability in the region is also due to grow, with drive-thru clinics opening at Belmont and Anna Bay.
It comes as the Hunter added three fresh cases on Monday amid concerns about unknown chains of transmission in the community.
The casual sites Hunter New England Health added overnight include:
Health authorities had earlier identified BP Cessnock, at 36 Wine Country Drive, as a casual exposure venue between 9.30am and 9.40am on Wednesday August 25.
Big W, Market Place, Raymond Terrace on Tuesday 24 August from 9am - 5pm and Wednesday 25 August 9am - 5pm was also flagged as a casual exposure, but Hunter New England Health said it was likely to class specific people who attended as close contacts.
"Urgent review of CCTV footage is currently occurring. NSW Health will contact these people who are considered close contacts," the health district said in a statement.
Foodworks at Whitebridge is also a casual contact site between Friday 27 August from 4.40pm - 4.45pm.
Anyone who visited the exposure sites during those windows must get tested and isolate until they receive a positive result.
Authorities also upgraded a previously identified site, at Subway in Raymond Terrace's Marketplace shopping centre, from a casual to close exposure between 11.55am and noon on Wednesday August 25.
Close contacts must get tested and isolate for 14 days, and await further advice from NSW Health:
Wallsend-based Medtech Services and partner 4Cyte Pathology will add an Anna Bay drive-through testing site to its growing stable from Wednesday.
The Port Stephens site, in the HopeUC church car park at 4326 Nelson Bay Road, will be open 7.30am to 3.30pm Monday to Friday starting September 1.
It follows a Belmont pop-up clinic at Barton Oval that opened on Monday, and is open 7.30am to 3.45pm.
Both sites may expand their operating hours if demand requires, Medtech Services said.
The sites join the firm's testing clinics at Charmhaven, East Maitland, Speers Point, Wallsend, Warners Bay and Wickham, as well as a Lake Macquarie clinic for emergency services workers.
