In 1988 Corporate Investments Limited took over the business and several routes were withdrawn. In 1991 an agreement was reached where competitor Mount Cook Group ceased operating in the North Island and Newmans ceased operating in the South Island. This step was not enough and in 1992 TTRB Ltd, a consortium of four coach operators (Tranzit Group, Taranaki Coachlines, Ritchies Transport and Bayline Group), took over Newmans Coach Lines. By 1994 two of the consortium members had withdrawn and the remaining two shareholders Tranzit and Ritchies operated it as a separate business until the Auckland power crisis in 1998 when Newmans was integrated into the InterCity Group business.
