Anyone who was at New World Kaikohe between March 20-30 may have been exposed.

However, people will only be tested if they display symptoms of Covid-19, health officials say.

"Testing well people can create a false sense of security," Northland DHB Medical Officer of Health Dr Catherine Jackson says.

"Just because you test negative today, doesn’t mean you won’t get Covid-19 and test positive another day. The best time to be tested is if you have symptoms."

No one has been hospitalised in Northland, Northland DHB says.
