Born in Jerusalem in 1952, Noked studied law at the Hebrew University of Jerusalem.[2] She became a legal advisor to the Kibbutz Movement in 1986, a job she held until 1992. Between 1996 and 2002 she served as director of the movement's legal department. She has also been a member of the Jewish National Fund's directorate, the Agricultural Association's secretariat, the National Council for Environmental Quality and the board of the Israel Lands Authority.
In the 1999 elections Noked stood as a Labour candidate within the One Israel list. Although she did not win a high enough spot for a Knesset seat in the party primaries, she entered the Knesset in August 2002 as a replacement for former Foreign MinisterShlomo Ben-Ami. She retained her seat in the 2003 elections, and briefly served as Deputy Minister of the Vice Premier[3] under Shimon Peres between January and November 2005. In the run-up to the 2006 elections she won 17th place on Labour's list (a slot reserved for kibbutz members - Noked lives in kibbutz Shefayim). With the party winning 19 seats, she retained her seat and served as a member of the influential Finance Committee.
