Parts of Glenholme School in Rotorua have been contaminated by raw sewage after storm water drains on the surrounding streets overflowed.
In a post on its Facebook page tonight, the school said it had "fallen victim to the torrential rain and continuous bad weather".
It said council storm water drains on Ranolf St and Malfroy Rd had overflowed and "caused havoc" at the school.
"Raw sewage from surrounding homes has contaminated some of the school.
"The school entrance, the hall and some [of] the field has been hugely impacted by this and a massive clean up will be taking place tomorrow. The Council and Ministry of Education will be involved in this process."
