Haase's career began 1952, when she introduced herself at 18 years at the SC Dynamo Berlin, which looked for high-speed ice skaters to the world and married thereupon her coach Helmut Haase.

From 1957 to 1967, Haase (hare) reached 15 GDR master skating titles on separate distances (Einzelstrecken), an additional seven titles in combination results (samalog, or Mehrkampf in German) and a further four on a very small indoor rink (Kleinbahn), a fore-runner of present indoor short track skating.

In preparation for the Olympic Winter Games of 1960, she went to Davos with the ladies of the unified German team and broke the multi-combination world record in Davos, Switzerland.

She also won the silver medal over 1000 m and finished at a respectable 8th place over 1500 m, and all of this despite the prohibition of the entry for her husband/coach.

In the Olympic season of 1964, she reached again peak performance,[peacock prose] with a fourth place in the 1000 m and a fifth place over 1500 m with the Olympic Games in Innsbruck.
