During the 1987 general election, conservative Christian elements including the Society for the Protection of Unborn Children (SPUC), Women for Life and the Coalition of Concerned Citizens tried to infiltrate the National Party by running conservative Christian individuals as candidates. Conservative Christian groups and periodicals like the "Coalition Courier" and "Challenge Weekly" also attacked the Labour government's policies towards peace education, sex education, abortion, and Maori biculturalism. However, they met little success in this effort and the National Party leadership responded by quietly centralizing its candidate selection procedures. Increased evangelical political activism did, however, set the stage for the emergence of several evangelical Christian political parties during the next twenty-five years (see below).
