A mystery illness - which forced Westport North School to close after a third of the pupils became ill - remains unknown as health officials wait for results.
Sixty-six pupils at Westport North School were away sick yesterday, forcing the school to shut until at least Friday.
West Coast District Health Board medical officer of health Ramon Pink said the DHB could not comment on the cause of the illness until it has the results.
Dr Pink said an influenza-like illness was currently circulating throughout the West Coast, and advised people who were unwell to stay at home.
Westport North School said it would decide tomorrow whether to reopen on Friday or not.
