Foreign Minister Julie Bishop said Australia's relationship with New Zealand was the closest and most comprehensive of all its bilateral relationships, and was built on a foundation of strong historic and cultural ties.
"Together we work to promote economic growth, stability and security in the Pacific region and beyond. We are committed to further deepening our relationship and to continuing collaboration on the basis of our shared values and interests," Bishop said.
Bishop said McDonald was a senior career officer with the Department of Foreign Affairs and Trade. Most recently he served as a deputy secretary overseeing the Australian government's aid and development work, which has a focus on the Pacific region where over 25% of the aid budget is spent.
In Canberra he has held a range of positions as well as working in a range of departments for the Victorian state government.
"I thank previous high commissioner Peter Woolcott for his contributions to advancing Australia's interests in New Zealand since 2016," Bishop said.
