Nawrocka assumed the role after her husband Karol Nawrocki was sworn in as Poland's next president before both houses of parliament.
The ceremony ended Agata Kornhauser-Duda's decade as first lady alongside President Andrzej Duda.
Rafał Leśkiewicz, spokesman for the incoming president, said Nawrocka was planning use her time in the presidential palace to focus on shielding children and teenagers in the digital world, expanding equal education opportunities and combating online abuse.
Issues affecting people with disabilities are also close to her, he added.
Born on March 7, 1986 in the Baltic city of Gdańsk, Nawrocka has worked 18 years at the National Revenue Administration, dealing with fuel-market oversight and illegal gambling.
She plans to take unpaid leave after becoming first lady. Her initial initiatives will be outlined shortly after Nawrocki’s swearing-in, according to Leśkiewicz.
The new Polish presidential couple have two children, Antoni and Katarzyna, and also raised Daniel, Nawrocka's son from a previous relationship.
On Wednesday, Karol Nawrocki was sworn in as Poland’s new president, officially beginning his five-year term after taking the oath of office before a joint session of parliament.
Kornhauser-Duda accompanied her husband on official visits during his two-term presidency and backed civic efforts, including more than 717 social and educational initiatives and 463 charitable campaigns, according to the Polish President's Office.
Her work emphasized education, disability and senior issues, and volunteering. She largely avoided media engagement, giving few interviews—her last official press interview was in 2015—with public remarks mainly at official visits and state ceremonies.
