What is wastewater testing for Covid-19?
Wastewater testing for Covid-19 first started in April 2020, with the aim of giving an early warning of outbreaks or an additional surveillance tool. The science has been developed since then, with a test in November 2020. The number of sites has steadily expanded and ESR now does regular wastewater testing across sites in Auckland, Wellington, Christchurch, Rotorua, Hamilton and Queenstown. The samples are processed in ESR s laboratory in Wellington, and checked for accuracy – including adding a cat coronavirus and a mouse norovirus to every sample as controls.
