It's sadly ironic that it is exactly 70 years since the last time we made the mistake we seem to be making all over again.
In 1945, one of the biggest historical events of the modern world was only weeks from drawing to a close. Peace was a breath away. Years of fighting were nearly over.
New Zealand told itself it had done its bit in World War II. We had sent brave boys to their deaths. We had sent comfort parcels to Europe. We had rationed and scrimped like everyone else in the world.
But we didn't pull our weight in rescuing refugees. The US, England and even Australia opened their doors to Jews fleeing the Holocaust and we sat like a child with crossed arms at the end of the world refusing to participate.
Back then our immigration policy was aimed at keeping New Zealand white. It's ridiculous to think that now, when you consider our Asian faces, Indian accents and Pacific Island citizens. But as recently as the 1970s, this country was not keen on anything browner than an Englishman straight out of a Northern Hemisphere winter.
