A NSW Service Centre will be established at Miranda by the end of next year.
Finance and Services Minister Dominic Perrottet announced new "one-stop shops" for state government transactions would open at 34 more locations, including Miranda, over the next 18 months.
Mr Perrottet, who promoted the expansion with Liberal candidates Eleni Petinos and Mark Speakman, was unable to be more precise about the timing.
At present, there are 26 NSW Service Centres and Hurstville is the closest to Sutherland Shire.
The centres take over the functions of motor registries and also handle many other transactions, including boat registrations, birth certificates and Seniors Card applications, owner builder permits and public housing payments.
Mr Speakman said the location of the Miranda centre had not yet been decided.
He said Service NSW would work with the local community, council and other relevant parties over the coming months to ascertain the best location.
Specific criteria, including accessibility, parking and proximity to public transport, had to be met, he said.
