"There were 282 swabs taken in managed isolation and quarantine facilities yesterday," the ministry said.
The Ministry said these testing numbers were strong - "Please continue to seek advice on getting a test if you have cold or flu-like symptoms."
The statement reiterated that it isn't necessary for the public to wear masks at Alert Level 1, because there's no evidence of community transmission in New Zealand.
"Masks will be most useful when Covid-19 is present in our community and people are in situations where they are in close proximity to each other."
Meanwhile, the ministry said pop-up testing centres continue to be popular and are playing an important part in helping the country rule out any potential for Covid-19 in the community.
Taranaki District Health Board is holding a pop-up in central New Plymouth today from 1-3pm at the New World carpark for members of the public to get swabbed.
Mid Central are running two testing stations in Palmerston North today – one in the carpark of New World Pioneer and the other at an event at the Pasifika Community Centre at Bill Brown Park.
The metro Auckland DHBs will be providing free COVID-19 swabbing at a pop-up surveillance testing site in Manurewa this weekend.
The drive-thru/walk-thru testing centre will be set up at the Southmall car park, entrance via Weymouth Road, Manurewa, on Saturday 8 August starting at 9am until 4pm.
There will be a pop-up testing clinic for Canterbury people without symptoms who wish to be tested for COVID-19 – again this Saturday 8 August.'
The Ministry also today reported that 641,400 people have downloaded the Covid-19 tracer app.
There have been 86,224 posters created, and 1,987,955 poster scans. There have been 65,803 manual entries recorded in the app.
"The Ministry has received feedback that some businesses have stopped displaying their QR codes. We are getting in touch with every organisation that has generated a code to provide another copy of their poster along with guidance on where to display it."
Yesterday Health Minister Chris Hipkins recommended that all Kiwi households should add masks to their earthquake emergency kits.
"It is not necessary for the public to wear masks at alert level 1, because there is no evidence of community transmission in New Zealand," the ministry said.
