There are 3805 new cases of Covid-19 and 466 people in hospital with the virus.

A further 16 Covid-related deaths have been reported today.

Eight people with Covid-19 are in ICU.

One person whose death was reported today was from Northland, two were from Bay of Plenty, one was from Tairawhiti, two were from Taranaki, one was from Whanganui, two were from Wellington region, two were from Canterbury, one was from West Coast, three were from South Canterbury, one was from Southern.

One was in their 60s, two were in their 70s, 10 were in their 80s and three were aged over 90. Four were women and 12 were men.

"This is a very sad time for whānau and friends of those who have died and our thoughts and condolences are with them," the Ministry of Health said in a statement.

There have been a total of 1815 deaths confirmed as attributable to Covid-19 to date (either as the underlying cause of death or as a contributing factor).

In the past seven days, there has been an average of 11 deaths confirmed each day as being attributable to the virus.

Of today's 3805, 144 people had recently travelled overseas.

Today's numbers come as new wastewater results from ESR have revealed Omicron variant BA.5 has continued its takeover and is now by far the most dominant strain across New Zealand.

The research from the Institute of Environmental Science and Research shows BA.5, which was first identified in travellers in late April 2022, is now at 91 per cent and has overtaken the previous Omicron variant BA.2.

According to the ESR data, BA.2 now only represents 3 per cent of cases.

The findings also show BA.2.75 and BA.4.6 are still very rare in New Zealand at the moment.

The results are part of the most recent Covid-19 genomics report released by the ESR in conjunction with Massey University, The University of Auckland and The University of Otago.

The recent ESR genome sequencing

In the two weeks from July 30 to August 12, the ESR analysed the genome from 1394 cases.

There have been 18,000 cases tested this year.

In a post on Twitter, ESR genetics expert Professor Michael Bunce described the community genomes data as "a solid surveillance net for Aotearoa".
