Visitors were being asked not to leave their cars on arrival and to follow directions for traffic management.
"Our staff will take you through a checklist and if you do fit the criteria, we will register your details and make a time for you to come to an isolated section of our Northcross clinic for testing," the centre said on the website.
"You may receive a txt update if your time changes.
"You will be directed to the testing station and our staff will come to your car.
"If you arrive without phoning first, you will be given these same instructions and directed away to call and make a time with our team.
"Please note there will be very limited parking available due to site constraints."
The clinic said staff assessing patients were required to wear a gown, mask, glasses and gloves.
"You may need to explain this to young children in advance to avoid them getting frightened."
The Herald contacted the medical clinic for comment but they declined.
A Ministry of Health spokeswoman said: "We can not provide an answer to your questions today but you can expect more on community testing clinics in our updates tomorrow."
The Herald reported this week that community testing centres for Covid-19 would operate throughout Northland from Thursday but people were being advised that they will not provide medical assessment or care.
Northland DHB Medical Officer of Health Dr Catherine Jackson said if people felt unwell or were sick enough to normally see their GP, they should make an appointment with their doctor rather than going to a testing stations.
"The centres are for testing only and will not be providing medical care or assessment.
"The aim of the centres is to take the load off general practice teams and emergency departments and reduce exposure risk for healthcare workers in other walk-in care locations."
