There are 13 new cases of coronavirus, the Ministry of Health confirmed on Saturday.

That brings the total number of cases to 1422, while the number of recovered cases sits at 867, up 51 on Friday.

The new cases today are made up of eight confirmed and five probable cases. This is an increase on Friday's tally of eight, the lowest number of new cases to be announced since the level 4 alert began.

The new cases were confirmed after a record breaking number of tests were processed on Friday.

Twenty people are in hospital with Covid-19, three of them are in intensive care and of those, two are in a critical condition.

The number of fatalities stands at 11, after the deaths of two more patients which were announced on Friday.

The Government took a one day break from its usual schedule of 1pm press conferences and instead delivered a written update.

Health officials have expanded their targeted testing of communities that may have been exposed to Covid-19 to two Auckland supermarkets.

Targeted testing for undetected community transmission has already taken place in Queenstown, Waikato, and Canterbury.

All of the Queenstown and Waikato tests have now been processed and returned negative.

Not all of the tests for the Canterbury site have been processed yet, but the ones that have been have all returned negative results.

HAGEN HOPKINS/STUFF Director-General of Health Ashley Bloomfield will be taking a break from press conferences on Saturday.

The Auckland testing began at 8am with the goal of taking 150 swabs at each site.

On Friday, labs processed a record 4677 tests for Covid-19, bringing the total number of tests to 79,078.

The number of new cases announced this weekend will help guide Cabinet as it decides on whether or not to relax lockdown restrictions by moving from a level 4 to a level 3 alert.

Finance Minister Grant Robertson said on Friday that all options were still on the table, including remaining at alert level 4.

He remarked that similar lockdowns had recently been extended around the world.

"I share this as a reminder that this is a long game — a marathon, not a short sprint," he said.

This decision will be made on Monday, two days before the initial four week period spent in level 4 is due to expire.

The Ministry of Health has not yet delivered an update on the death of an Invercargill man of suspected Covid-19.
