Catherine Isaac is the president of the New Zealand political party ACT, and managing director of Awaroa Partners.
[3] Isaac was communications and public affairs manager for the National Provident Fund through its extensive restructuring from 1988 to 1991.
Her bid for the presidency was support by the founders of ACT, Sir Roger Douglas and Derek Quigley.
[9] Isaac was one of a handful of people that Richard Prebble confided in prior to announcing to the ACT caucus on 27 April 2004 that he intended to retire as leader of the party.
She was ranked second on ACT's party list, but did not stand as an electorate candidate because of her husband's illness.
