A potential solution to the growing need for building materials is the use of reclaimed and recycled building materials (RRBMs) in New Zealand. Therefore, it is important to understand the attitudes and behaviour of the key stakeholders. This paper looks at the behaviour of three key construction industry stakeholder groups in New Zealand—architects, builders and consumers; and was conducted through the lens of the Theory of Planned Behaviour (TPB) by the means of an online survey questionnaire. While environmental attitude was always a strong predictor for intention and behaviour, the study found that the detailed considerations differed for each group. Architects found perceived behavioural control to be more important than consumers and builders, while the behavioural intentions of the latter could be predicted by the subjective norm. Reuse and recycling behaviour was more predictable based on the TPB components, and specific use of RRBMs was predictable for architects and builders. Policymakers can enhance perceived behavioural control by increasing designers’ awareness with help of educational programs and using new ways of communication.

Keywords: reuse and recycling; building materials; stakeholders; Theory of Planned Behaviour.
