Wishart continued working on the project as a special investigation for TVNZ, to be carried out in secret with the assistance of "Frontline" journalist Michael Wilson and producers Carol Hirschfeld and Mark Champion. The documentary was originally scheduled to air in December 1993, but was prevented from going to air by TVNZ management after the intervention of the TVNZ board of directors. Wishart and his colleagues decided to leak details of the banned programme to other news media, turning the blackout into a public issue.
