To ensure the work is completed on time, both the Stratford and Hāwera service centres will temporarily close, but at different times.
Stratford Service Centre in Miranda St closed on Monday, June 28 with plans for it to reopen to the public on Tuesday, July 13.
The Hāwera Service Centre in Union St will be temporarily closed from Monday, July 19, reopening on Tuesday, August 10.
Gloria Campbell says people will continue to receive help.
"The centre is closed but all services continue regardless. We found during lockdown that many people adjusted to accessing our services remotely and options such as the 0800 number and MyMSD give them greater flexibility."
