Australia's closest ally has raised alarm at the coalition's leadership turnover, even joking it may not be worth building a relationship with the new shadow foreign minister.
New Zealand foreign minister Winston Peters says he is "aghast" at the "inexcusable" turmoil in Australian political ranks which he attributes to "ego".
Mr Peters is in his third stint as New Zealand's top diplomat, having served in the governments of Helen Clark, Jacinda Ardern and, currently, Christopher Luxon.
