The men’s teams were unbeaten, but at the time there was not a national competition. After the Dutch national volleyball federation, Nederlandse Volleybalbond, was founded in 1948 the women’s team started winning prizes. The team became in the second year (1949) national champion. The women’s became again national champion in 1955, 1956, 1958 and 1959. The team also played internationally, including to Moscow in 1962 during the Cold War. In later year, when Blok still had an assisting role, the team became national champion in 1964, 1965, 1966, 1967, 1969 and 1972 (the later two under new club name Haag ’68).
