John Key has imported to New Zealand one of the longest running arguments in Australian politics with his concession to Prime Minister Gillard at the weekend that will see New Zealand accepting 150 "boat people" a year from Australia's off-shore processing centres. To critics, New Zealand will be complicit in an inhumane and punitive system of detention beyond the protection of law.
Julia Gillard's Labor Party used to share that view. When it came to power in Canberra it closed the centres on Nauru and Manus Island in Papua New Guinea that had been established under John Howard's Pacific Solution. But under the pressure of illegal immigration the Labor Government soon re-opened them and built additional processing facilities on Christmas Island and at Darwin.
These tropical holding pens are undoubtedly hot and unpleasant. The United Nations High Commissioner for Refugees has criticised the lack of air conditioning at Nauru and the inadequate health services for those who may be suffering from previous torture and trauma and likely to be in delicate mental and physical condition.
But it is hard to see what else Australia can do. Its northern coasts are within reach of unapproved migrants as well as genuine refugees. The island camps are undoubtedly intended to deter people from setting out, and the conditions in the camps can hardly be worse than those refugee families would face if they made it to shore in the outback.
