Kāpiti Coast District Council has closed the Waikanae Library and Service Centre as a precaution, following air quality test results showing the presence of toxic mould.
Regulatory services group manager Natasha Tod said the closure isn't an ideal situation, but they take seriously any potential risk to the health of staff and customers.
"We recently carried out air quality testing at the Waikanae Library and the results show that two types of mould are present that are of concern - one is non-toxic (penicillium/aspergillus) but has the potential to cause hay fever-like symptoms, and the other is toxic (stachybotrys).
"The testing was carried out to assess whether leaks and water damage in the library building posed a risk to the health and safety of staff and customers.
"The toxic mould was present in three of the four sites sampled within the building.
