A trans-Tasman spat has erupted with the Prime Minister criticising Australia for revoking the citizenship of a suspected Islamic State terrorist.
The 25-year-old New Zealand-born woman was arrested with her two young children when they were stopped at the border between Syria and Turkey.
She had dual New Zealand and Australian citizenship, but her Australian citizenship was revoked last year -- meaning she could be deported here.
Jacinda Ardern has accused Australia of abdicating its responsibilities.
Robert Patman, Professor of International Relations at Otago University, spoke to Corin Dann.
