About 900 people were tested for Covid-19 in the Bay of Plenty region yesterday, the Bay of Plenty District Health Board estimates.
Incident controller Dr Joe Bourne said there was a "dramatic increase" and they were still waiting for final figures.
"More than 250 people were assessed at Accident and Healthcare on Second Ave and 150 people attended the Te Puna Ora O Mataatua mobile clinic in the Eastern Bay of Plenty.
"The vast majority were tested at general practices and Pathlab facilities following a referral from general practice."
