A school on the South Island's West Coast has been closed due to a mystery illness.
Westport North School had 66 students off sick on Monday, out of a roll of around 189 students.
"There are some very nasty bugs doing the rounds. Please do not send your child to school if they are unwell and keep them home for 48 hours after they last show any symptoms," the school's Facebook page said on Monday.
The school website says the Board of Trustees has decided to shut down the school for three days.
It will be disinfecting and cleaning all of the schools' surfaces and will decide whether to reopen on Friday.
