Australia has been given another chance to transfer refugees from Manus Island in a renewed offer from New Zealand to resettle 150 people.

New Zealand Prime Minister Jacinda Ardern says her government remains willing to accept the refugees on humanitarian grounds, confirming the number of places during her visit to Australia last Friday.

Prime Minister Scott Morrison has rejected the chance, saying it would weaken border security, despite calls for urgent action from Papua New Guinea Prime Minister James Marape and Manus Island Governor Charlie Benjamin.
