In 1945, Greta Kuckhoff re-joined the KPD and in May 1945, was appointed the leader of the postwar reconstruction Bureau of Denazified and Abandoned Factories (Amtsstelle für die entnazifizierten und herrenlosen Betriebe) in Berlin.
In April 1946, she became a member of the Socialist Unity Party (Sozialistische Einheitspartei Deutschlands, or SED) when the KPD leadership forced a merger with the East German Social Democrats.

She, Adolf Grimme and Günther Weisenborn attempted to gain legal redress against the former Nazi judge who had convicted them all, Manfred Roeder.
After years of delays by the Lüneburg state's attorney, the case was dropped at the end of the 1960s.

Beginning in 1946, Kuckhoff worked in business and government within the German Democratic Republic (GDR), working within the SED and organizations.
From 1949 to 1958, she was a representative in the provincial Volkskammer; from 1950 to 1958, she was the president of the central bank that preceded the GDR's Staatsbank.
In 1958, she had a disagreement within the SED and was forced out of the bank, though officially, she stepped down for her health.
Following her removal from the bank, she became active in the Peace Council of the GDR.
In 1964, she became vice president of the Council and a member of the World Peace Council.
In 1972, she published her memoirs under the title, Vom Rosenkranz zur Roten Kapelle.

Kuckhoff died in Wandlitz.
Her ashes are buried at the Memorial to the Socialists.
