Asymptomatic testing is when you're tested for COVID-19 but don’t have any of the symptoms commonly seen in COVID-19. Asymptomatic testing is only done to certain groups of people and is directed by the Ministry of Health and Public Health Units.
It's used in groups where there's a higher risk of having COVID-19. It can pick up the small number of cases that don't develop symptoms or are in the early stages of the infection. It's used alongside infection prevention measures to keep you, your whānau/family and community safe.
People who work at the border will be told by their employers how they can be tested and how often they should be tested.
Members of the public usually don't need asymptomatic testing. But the Ministry of Health may sometimes ask for a sample of people to be tested. This is to let them know if there's any undetected spread in the community. This is known as community surveillance.
