The Auckland central library will partially reopen this weekend and is undergoing further precautionary testing to air quality after an "unpleasant smell" was noticed.
The central library closed last week.
Air quality testing has shown there are no indications of adverse health and safety impacts.
"All results from that round of testing have come back clear and we can assure people who were in the library at that time that whilst the smell was very unpleasant, there was no harm to health."
However, futher independent testing has been requested.
As it waits for the results of the independent testing, customers will be able to use a 'pick-up and returns' service from Saturday 10 April.
Customers will be able to collect books they already have on hold and return any books that are due back.
The service will be available 10am - 5pm on weekends and 1pm - 6pm Monday to Friday.
Staff numbers will be limited and customers will not be able to access other services or areas in the building.
