There are 20 venues of concern linked to two positive COVID cases in Port Macquarie.

Mid North Coast Local Health District released the extensive list on Sunday night (September 26) after the two cases were confirmed, along with another case in Kempsey.

Anyone who attended the following venues at the times listed is a close contact and must get tested immediately and isolate for 14 days regardless of the result:

United Projects is a building and development company and owner Joshua Daley said the news was devastating.

The development on Gore Street employs about 50 local workers in Port Macquarie and all have been forced to isolate for 14 days.

"My company has been forced to shut down and we can't do anything productive for the next two weeks," Mr Daley said.

Mr Daley was site manager at Gore Street on the days the site was impacted but said none of his staff were positive COVID-19 cases.

United Projects has followed all NSW Health safety regulations and were alerted to the news via a QR code notification.

Bills Fishhouse and Bar posted on their Facebook page stating their emotions are rife for their family, team, guests and the community.

"We will continue to work with NSW Health and follow advice," the post said.

"We will see everyone soon, until then be kind and stay safe."

The business has been forced to close its doors after a COVID-19 positive case visited the restaurant on Saturday, September 18.

Meanwhile Blue Cow Gelato manager Daryan Scott said staff who were on shift on Saturday, September 18 have gone into isolation and are being tested, in line with NSW Health regulations.

The store opened to the public on Monday, September 27 after being deep cleaned.

Ms Scott said herself and the owner were providing ongoing support to their staff.

Anyone who attended the following venues at the times listed is a casual contact who must immediately get tested and isolate until a negative result is received. Please continue to monitor for symptoms and immediately isolate and get tested if they develop:

If you are directed to get tested for COVID-19 or self-isolate at any time, you must follow the rules given to you by health staff, whether or not the venue or exposure setting is listed on the NSW Health website.

The two cases are from the Port Macquarie area and are close contacts of a positive case who visited the region last week.

They have been isolating since being identified as close contacts.

The North Coast Public Health Unit is currently investigating these cases and contact tracing is underway.

The third case is in Kempsey and is a household close contact of a case reported on Saturday, September 25. This person has been in isolation and has not been infectious in the community.

Positive cases in the Mid North Coast Health District now total 10:

There have been 16 cases reported in the MNCLHD since the beginning of the current NSW outbreak in June.

Port Macquarie Airport and two businesses in Nambucca Heads have also been listed as venues of concern after two other confirmed cases of COVID-19 visited the region separately.

These venues of concern are not related to any of the current cases at Coffs Harbour and Kempsey.

All residents in the Kempsey LGA must stay at home unless it is for an essential reason, which includes:

People who are fully vaccinated can attend an outdoor gathering of up to five people for exercise or outdoor recreation, as long as all of those aged 16 or older are fully vaccinated.

To determine the extent of the risk and detect any further potential COVID-19 cases in the area, the MNCLHD is calling on the communities to come forward for testing in large numbers.

Kempsey commenced a seven-day lockdown at 5pm, Tuesday 21 September. Cases numbers will determine the outcome of a review after this seven days is complete.
