It said the figure marked the third straight monthly drop in joblessness as the economy emerges from the coronavirus crisis.
There were around 1,028,300 people without jobs across the nation at the end of May, down by 25,500 from a month earlier, according to the Polish labour ministry.
The state-run Central Statistical Office (GUS) reported last month that the Polish jobless rate dropped to 6.3 percent in April, from 6.4 percent in March.
Meanwhile, the European Union’s Eurostat statistics agency, which uses a different methodology, estimated last week that unemployment in Poland held steady at a modest 3.1 percent in April, the lowest rate in the 27-nation bloc.
Polish Deputy Prime Minister Jarosław Gowin has said that the government has spent tens of billions to save more than 6.9 million jobs since the coronavirus crisis hit the country in March last year.
Support for businesses throughout the country has exceeded PLN 200 billion (EUR 44 billion, USD 52 billion) over the past year or so, he added.
President Andrzej Duda in late January signed into law Poland’s budget for 2021, which expects the country's unemployment rate to rise to 7.5 percent by the end of this year, from 6.2 percent at the end of 2020.
