As we become more globally connected more than half the world lives in cities which are becoming more ethnically diverse.
Immigrants overwhelmingly choose to migrate to cities because that's where opportunities exist on a large scale. Cities feel urbanisation and immigration profoundly.
They can be contentious policy issues at national level. But at city level, they are lived realities.
Having listened to many great examples from speakers from around the globe at the Cities of Migration conference in Berlin, I am convinced Auckland - with more than 40 per cent of our population born overseas and 12-14 per cent of children born to immigrants - has a huge competitive advantage over other cities.
As one of the most migrant-rich cities in the world, we must court diversity to build on our strength, vitality and innovation. But the growing negative conversation around migrants in this country is threatening the very positive progress as we grow.
