There are 49 new cases of Covid-19 in the community today, with all of these cases in Auckland.
This brings the total number of cases to 725 with 709 in Auckland and 16 in Wellington. There are also four new cases to report in managed isolation and quarantine.
Dr Ashley Bloomfield says the lower cases numbers today are encouraging and show the alert level 4 measures in place are working.
He says the numbers could still bounce around a little.
There are 42 cases in hospital with 8 in North Shore, 19 in Middlemore and 15 Auckland. Six of the cases are in ICU or HDU.
Prime Minister Jacinda Ardern says the case numbers moving around is not unusual and was seen last time.
She says there are some positive trends, the rolling day average of cases is decline it is 61 today and was 77 five days ago.
There are also fewer cases that were infectious in the community, of the 49 cases announced today only seven were infectious in the community, says Ardern.
She says the people aren’t breaking the rules with most of the exposure events being from visiting a supermarket or dairy.
Cases of in-household transmission would continue to be found, says Ardern, but lockdown is necessary for extinguishing those last chains of transmission.
"If you are a contact, if you have been at a location of interest and advised to stay home as a result you absolutely must do so. It is such an important message."
Ardern announced Northland will move to alert level 3 at 11.59pm tonight.
Earlier: Prime Minister Jacinda Ardern, Director-General of Health Dr Ashley Bloomfield and Minister of Defence Peeni Henare will provide an update on the current Covid-19 outbreak.
They are expected to be live from Wellington at 1pm.
