This paper examines the models of internationalisation adopted by thirty firms from New Zealand. Analysis of the international model is based on five key dimensions: firm sector and size; international market scope; market entry and servicing strategies; and speed of internationalisation. Drivers and constraints to internationalisation are also considered in the analysis. Evaluation of these dimensions over time finds evidence of both traditional ‘stages’ and emergent ‘born (again) global’ models of internationalisation, and reveals that over one third of these firms experience dramatic change to their international activities and resources initiated by divestment or change of ownership. We refer to the alternative internationalisation trajectory adopted by these firms as the ‘transformational’ model of internationalisation. The paper makes a contribution to the extant literature by providing synthesis of the New Zealand internationalisation and by building on our understanding of how patterns of internationalisation from a small open economy are changing in response to global environmental pressures.
