The latest summary of wastewater testing results for COVID-19 detected the virus in 22 samples tested over the week to 18 December. Sampling has taken place in 122 sites this week.
Currently, ESR conducts testing of samples collected from locations around New Zealand. When there are known cases of COVID-19 in the community ESR may increase the number of tests being undertaken, while, when the risk is considered to be lower, it may reduce the number of sites being sampled.
The frequency of sampling will vary depending on the local population, access to wastewater collection points and risk factors.
ESR says a huge 'thank you' to everyone involved in this important work in the lead up to Christmas.
