An aggressive and fast-moving gastro bug has struck a Hawke's Bay primary school, forcing more than a hundred students to stay away from classes.

Greenmeadows School principal Mark Johnson said he was told at the weekend a number of children in one class had fallen till with a vomiting bug.
The bug typically lasts a couple of hours.
The school's water supply has tested clear and cleaners have been through the school buidlings.
Mr Johnson said about 150 children are off today, some as a precaution, but he was confident the worst was over.
He said they did consider closing the school, but decided they didn't meet the threshold.
