The Research Collections and Nga Wahi Rangihau on first floor of Tauranga Library will also remain closed.
Wallis also reassured people that there would be no overdue charges for items due during the lockdown.
"74,000 items were out at the time of lockdown and although these can now be returned, there's no rush. To avoid people returning all their books at once, we have extended the due date to June 30, 2020."
So they don't have to browse the library, members can pre-order items by placing them on hold through the library's online catalogue, or by calling staff on 07 577 7177
Opening hours will be (7 days) 9:30am to 3:30pm for the first two weeks, and normal hours will resume on Thursday June 4.
