Ecokids teacher Linda Gedye said the Hastings childhood care centre had taken extra steps to ensure the bug didn't spread after a few cases of children being sick.
"It hasn't been bad. Our policy says 48 hours but when a few cases came we asked if parents could keep them another day to try and keep on top of it."
Ms Gedye said the long weekend, where the children were kept apart for four days, had helped, along with cleaning and disinfecting the centre's facilities.
Te Mata School principal Michael Bain said very few children had been affected by the bug.
"It would be less than handful, I would have thought, that would have rung or notified us that they had some sort of gastro. We've got typical coughs and colds and numbers of kids that are away on that stuff."
The principal said the bug had largely evaded the school's patch and there hadn't been any indication that the school needed to notify the community further.
"When we had as mother ring saying her two-year-old was down and she was keeping their sibling home we contact the DHB and our public health nurse who made an inquiry around the local GPs to see whether we needed to put out anything with urgency."
Beststart deputy ceo Fiona Hughes said there had been no confirmed case of norovirus within the childcare facilities, which included ABC centres, but they had a few children with upset stomachs.
"We've got as strict policy about staying away for 48 hours during any kind of an outbreak. Parents are adhering to that and we're also reminding them about good health practices of hand washing to prevent infection."
The HBDHB said careful attention to hand washing and drying would help prevent the bug spreading, adding people with stomach bugs should not swim in public pools for two weeks as they could remain infectious for that period of time.
Parents were encouraged to ensure their children consumed plenty of fluids to prevent dehydration and have oral rehydration drinks while they were ill.
