He was greeted by a big crowd in the Split port. This marked the end of Vicko's war campaign. In December 1944, Vicko was made the commissioner for industry and trade of ZAVNOH. He stayed in Split during the first few months of liberation. In April 1945, he became the minister of internal affairs of the newly established Federal State of Croatia. He moved to Zagreb after the Ustashe government fled from it in May 1945. In January 1946, he became the minister of labour and maritime affairs in the Federal Executive Council of Yugoslavia. He then moved to Belgrade with his family. In April 1951, he became the president of the regional committee CP Croatia for Dalmatia and in February 1952, he became the President of the Presidium of the Croatian Parliament which was at the time the highest governing body in SR Croatia. After his term ended, he became the member of the Federal Executive Council in February 1953. From 1954 to 1958, he was the committee president in the SR Croatia parliament and a representative in the parliament from 1945 to 1963. From 1963 to 1967, he was the president of the budget committee in the Federal assembly and a representative in the assembly from 1945 to 1967. Vicko Krstulović was one of the designers of the SR Croatia coat of arms. Thanks to him, the sea was put in there. He also did much for his native Split and Dalmatia. As a committee president of Dalmatia, he was sent to Split in order to stop the chaos which was being done there. He helped on creating transportation systems in Split and connecting it more with the rest of the country. Vicko represented the idea that the new railway should go from Sarajevo to Split, and not to Kardeljevo but his idea was rejected. Vicko wrote the "Adriatic Orientation of Yugoslavia". It was a book about the sea potential that Yugoslavia has and how it should be used. He tried to persuade Tito on reading it but it was never seriously taken. Vicko criticised the new direction of the Communist party of Yugoslavia. He was against changing the party name in 1952 to League of Communist. He believed that the party was rejecting its revolutionary path and that it was starting to accept a bureaucratic-dogmatic way of functioning. He knew that the party was slowly becoming open to extreme careerism and it was ignoring all the old party members. The party members who were longer in the party than Tito were especially ignored and put aside.
