Foreign Affairs Minister Winston Peters will host Australian Minister for Foreign Affairs Marise Payne on Friday and Saturday as part of their six-monthly foreign policy discussions.
"Australia is New Zealand's most important bilateral partner and our relationship is overwhelmingly positive," Peters said in a statement.
"For two independent nations, Australia and New Zealand enjoy an unparalleled level of connection and integration. Our discussion will help ensure the trans-Tasman relationship is working effectively.
"We will discuss in depth the global and regional issues where we have shared interests."
Issues likely to be brought up include the treatment of detained New Zealanders in Australia, and trans-Tasman co-operation in the Pacific amid Australia's increasing concern over the influence of China in the region.
Beijing has poured billions of dollars in loans for infrastructure projects in the Pacific under President Xi Jinping's "Belt and Road" initiative.
