Traces of Covid-19 infections in wastewater samples are declining nationally, indicating a move out of the country's fifth wave.
Wastewater detection peaked on January the 7th at 8.46mil genome copies per person per day - today that figure has more than halved, equating to a total of 957 active recorded infections.
University of Canterbury's Professor Michael Plank says the data means hospitalisations should follow the trend down over the next couple of months.
Plank spoke to Ingrid Hipkiss.
