At least one Waikato school has cancelled its assemblies and postponed a disco to prevent the spread of measles.
Te Awamutu Primary School has not held an assembly since the beginning of term three, 11 days ago, because 25 of the school's 500 pupils were not immunised against the highly infectious virus.
And a fundraising disco planned for tomorrow night has been postponed while the school awaits an update on the outbreak.
A second wave of measles cases brought the total number of confirmed cases in the Waikato to 17 following an outbreak in Te Awamutu at the end of the school holidays.
The six new cases were unimmunised teenagers and children who were siblings of the first victims. One of the 17 infected was admitted to hospital.
