There are 49 new cases of Covid-19 in New Zealand today - all in Auckland

It's our lowest case number in six days.

66-percent of new cases to 9am yesterday were household contacts of an existing case.

77-percent of yesterday's 53 cases didn't create any new exposure events.

23-percent were infectious in the community, which could be a visit to the supermarket or being an essential worker.

33 people are in hospital, eight in ICU, with two being ventilated.

Ashley Bloomfield says based on updated modelling, the reproduction rate is remaining under one, which is successfully breaking chains of transmission.

He says it's sobering that six cases in Auckland are under the age of one.
