O'Connor said the number of test kits would not stop someone being tested at alert level 4.
"They would not be tested if they did not meet the case definition as it stood at that time," he said.
"However, even people who were not swabbed, as they did not meet the criteria, were still managed by our team, being advised to isolate as per alert level 4 restrictions and supported by follow-up phone calls to track their progress."
As of August 2, the DHB has tested 5176 people within the region.
The CBAC is still operating out of the hospital campus from Monday to Friday, 8am to 4.30pm and on Saturday and Sunday from 9am to 1pm.
Alternatively, people can phone their GP and may be able to get tested there.
"Whanganui DHB is confident in its procedures and is working to make sure it is prepared should there be a return of the virus," O'Connor said.
