Wastewater test results update

Wastewater testing continues to be a part of New Zealand’s testing and surveillance strategy in the fight against COVID-19. Recently, weak positive results were detected in Wellington, Christchurch, Rotorua and Queenstown. The Ministry’s assessment of these results is that there is a low risk to the New Zealand community.

We reported yesterday that subsequent testing from Queenstown and Wellington have returned negative results. We can now report subsequent testing for Rotorua returned a negative result.

We are awaiting the result from further testing in Christchurch and we will report this when available.

The Ministry’s current assessment remains that the weak positive results are likely from recent positive cases in managed isolation or due to recently recovered cases who are not infectious but continue to shed the virus after returning home or while travelling. There is no risk of infection from COVID-19 in wastewater.
