Covid-19 Response Minister Chris Hipkins has announced that voluntary daily Covid-19 saliva tests will be offered to quarantine workers in Auckland, Wellington, and Christchurch, Stuff reports. The saliva testing is a new precautionary measure put in place by the government, due to higher rates of infection overseas and the advent of more transmissible variants of Covid-19. Meanwhile, Minister Hipkins said that the saliva test is voluntary and will not replace nasal swabs.
