We address border security between Aotearoa New Zealand and Australia as a matter of an ascendant relationship, based on coordination and cooperation. By interrogating shared and divergent attributes between the nations, we are able to provide an overview of approaches towards regional threats. Behind these approaches are socio-political contexts, including drivers and authorities for cooperation as well as cultural and political identities. Importantly, the evolution of shared practices between the nations and a future scan of security in the region lead to important geopolitical considerations.Border securityTrans-Tasmangeopoliticalintergovernmentalsecurity threatsJournal article10.1080/14662043.2021.1992944449712Massey_Dark1606 Political Science
