Northland DHB is continuing Covid-19 testing with increased hours at their community-based testing centres and across the rohe, with Māori health providers' mobile services reaching into the smaller communities they currently visit.

Since the beginning of March more than 12,000 Northlanders have been tested via community testing.
Ortega added that good hand hygiene and covering coughs and sneezes were still important, particularly coming into the winter months.
"Influenza and other seasonal illnesses present very similarly, if yourself or anyone in your whānau become unwell call Healthline on 0800 611 116 or your GP for advice."
