Ethical conduct within consulting has become increasingly important since management consulting has developed into an independent profession. The objective of this research was to determine if differences exist in client consultant relationship ethics within a defined group of management consultancies in South Africa. A questionnaire was developed to assess ethical behaviour across five dimensions, namely the client consultant relationship, financial and contractual concerns, delivery of expectations, orientation and competence of consultants, and ethics in consultant behaviour. Thirty-nine respondents completed the questionnaire. Significant differences on ethical dimensions in relation to job level, between consulting firms, the level of senior management commitment to ethics and the existence of a code of ethics were obtained. Opsomming Namate bestuurskonsultasie as ‘n onafhanklike professie ontwikkel het, het etiese optrede binne hierdie professie algaande belangriker geword. Die doel met hierdie navorsing was om vas te stel of daar verskille ten opsigte van etiek tussen bestuurskonsultasie-ondernemings in Suid-Afrika is sover dit die kliënt-konsultantverhouding aangaan. ‘n Vraelys is ontwikkel om die etiese dimensie van bestuurskonsultasie oor vyf dimensies te beoordeel, naamlik die kliënt-konsultantverhouding, finansiële oorwegings, voldoening aan verwagtinge, oriëntasie en bevoegheid van konsultante, en die etiese gedrag van konsultante. Nege-en-dertig respondente het die vraelys voltooi. Beduidende verskille in die etiese dimensies ten opsigte van posvlak, die konsultasie-onderneming, die graad van senior bestuur se toegewydheid tot etiek, en die bestaan van ‘n etiese kode is gevind.
