New Zealand’s offer to resettle refugees from Australia’s offshore immigration detention system remains on the table, and the imminent end of Australia’s long-running US refugee swap could bring it under more urgent consideration from Australia.

The office of Jacinda Ardern confirmed to the Guardian that her country’s position had not changed – the longstanding offer to accept 150 refugees from Australia’s offshore islands each year still stood – but declined to confirm whether it was on the agenda for the New Zealand prime minister’s meeting with her Australian counterpart on Sunday. “We don’t discuss the content of bilaterals before they take place.”
