The government last month announced a loosening of COVID restrictions in several stages.
Shopping malls, DIY stores, museums and art galleries around Poland were allowed to reopen in early May after a fall in fresh coronavirus cases.
Officials on Friday reported 1,679 new infections, down from a high of 35,251 single-day cases on April 1.
As of Friday, Poland had injected around 12.37 million first doses of COVID-19 vaccines, while more than 5.2 million people had been fully inoculated, according to the health ministry.
