A Whangaparaoa College staff member is in self-isolation after their partner tested positive for COVID-19 on Wednesday morning.
The person is one of the eight new cases that was identified on Wednesday, which brought New Zealand's total number of cases to 20.
College principal James Thomas says the school has been in touch with the Regional Public Health Service and there is a low risk of infection for the community, local paper Hibiscus Matters says. This is because the staff member has not been at school for two days and is in "good health".
"I have been asked by the Ministry of Health to emphasise that contacts of contacts are not at risk and do not need to be worried," Thomas says.
A letter was sent to parents on Wednesday afternoon informing them of the positive case.
It says that the news may cause anxiety among parents and students. Parents are asked to explain to their children that the teacher doesn't have the illness and they haven't exposed anyone else to this virus.
Whangaparaoa College had previously taken a number of measures to help stop the spread of COVID-19. This included cancelling assemblies and postponing meet the teacher events, the school production, and other events, according to their website.
