Ahead of the 1999 general election, Wyngaard was listed 32nd on the party list of the New National Party (NNP), the NP's successor party, in the Western Cape. Wyngaard, along with Glen Carelse and Pauline Cupido, reportedly complained to the party leadership about their low ranking on the list.[3] Several weeks later, in January 1999, he and the others announced that they would resign from the NNP to join the Democratic Party (DP).[4] However, Wyngaard was not re-elected under the DP banner when the general election took place.[5]
