Philosophiae Doctor - PhD / Muslims and non-Muslim consumers regardless of who they are or from where they come, whether natives or foreigners in a particular country are much concerned with consuming food products. However, not any researchers in South Africa (SA) have addressed the consumers who buy food products labelled halal. This doctoral dissertation primarily aims to explore and bring new knowledge towards halal food purchasing behaviour. It specifically focuses on understanding the current purchase intention and behaviour of halal consumers in Cape Town, South Africa. For this purpose, the Theory of Planned Behavior (TPB) was utilised as the theoretical framework to measure the purchase intention and subsequently the buying behaviour of halal consumers. An exploratory sequential mixed method was adopted. A qualitative approach formed the first phase of the study, while a quantitative approach formed the second phase of the study. For the qualitative phase, data was collected purposively through 9 intensive semi-structured interviews. Nonetheless, for the quantitative phase, data was collected by means of 516 self-administrated questionnaires using a stratified random sampling. In analysing the qualitative data, thematic analysis was applied. However, for the quantitative phase, data was analysed using multivariate statistical analysis known as the Structured Equation Modelling (SEM).
