Lord Victor Olufemi Adebowale unveiled a commemorative plaque at the Rivers Centre Hub in Hellesdon.
He described the centre as “somewhere going forward” during the ceremony.
The three new wards form part of a £55 million development at the Hellesdon Hospital site, operated by the Norfolk and Suffolk NHS Foundation Trust (NSFT).
Zoë Billingham, chair of NSFT, said: “We are delighted he was able to do the honours and officially open the Rivers Centre.”

The new centre has been designed with patient wellbeing and recovery in mind, featuring therapeutic spaces, a gym, a community hub with a café and private en suite bedrooms.
Sustainability was a key focus in the design, with power supplied by solar panels and heating via air source heat pumps.
Service user Beatrice, who helped shape the project, said: “To have single rooms with a shower is amazing.
“It really makes a huge difference to people getting better.”
