Elizabeth Cecilia Wark QSM (née Te Wheao, 6 June 1924–16 May 2001) was a New Zealand social worker and politician.
Wark was born at Omanaia in 1924 to unmarried parents; Cyril Chapman and Nau (Mabel) Rini Te Wheao who was of Ngāpuhi descent.
The nuns who taught her provided her strong female role models, crediting them with giving her a moral base, integrity and social conscience.
She moved to Waihi, where her second son was raised by a local family while she continued to work, returning to Auckland in 1950 was employed in a clerical position.
She divorced Powell and married Jim Wark on 21 November 1966 at Auckland which gave her a stable home life for the first time.
She helped establish a hostel for young Māori who had been uprooted by urban renewal which was supported by the MWWL and the Catholic church.
In 1974 Wark was part of the establishment of Arohanui Incorporated, a community-based organisation to provide accommodation and assistance to youth referred from the justice and welfare system.
The hostel grew and with government funding literacy and numeracy classes as well as rehabilitating people with substance addictions.
