A school in Napier is telling all its pupils to stay home because there is so much sickness.
About 150 pupils are off sick at Napier Intermediate School - that's about 40 percent of the roll.
Six staff are unwell too.
School principal Wendy Gray said it has caused difficulties trying to teach on site, so pupils will have to learn from home for the next three days.
The Hawke's Bay DHB said a combination of flu, Covid-19 and other viruses is circulating in the community.
A spokesperson said the illnesses were putting significant pressure on the hospital and GPs, leading to a massive increase in school absences.
