The main building of Wairoa House on Spa Rd in Taupo has been temporarily closed following the removal of asbestos from two basement areas at the weekend.
Taupo District Council said this was to allow further testing to take place. The Ruapehu and Tauhara wings would remain open.
Specialist contractors are due on site tomorrow to undertake further air monitoring as a precautionary measure.
Facilities manager Garreth Robinson said the removal was completed successfully but some asbestos specialists would be undertaking further testing to confirm whether the site was safe for occupation.
Worksafe NZ has been notified and tenants were making alternative arrangements until the all-clear was given.
