The Ministry of Social Development expects to start moving into its new Napier office block next month.
The move involves Work and Income, Oranga Tamariki and housing operation Kainga Ora.
MSD East Coast regional director Michelle McNabb told Hawke's Bay Today the building on the corner of Kennedy and Wellesley roads will be completed and ready for occupation in mid-August.
The current MSD Service Centre in Vautier House and Dalton House, at the southern end of Dalton St, will close on August 13, with a new Service Centre open to the public in the new building from 8.30am the following Tuesday, August 17.
McNabb said the move will be done in stages, with teams from the three agencies progressively moving into the new centre between mid-August and mid-October.
