With record migration and a fast-growing population, Aotearoa New Zealand is changing. How that will look depends upon the interplay between people here now and those who want to come. So who is coming and does it matter?

With record migration and a fast-growing population, Aotearoa/New Zealand is changing.

How that will look depends upon the interplay between people here now and those who want to come. So who is coming and does it matter? What is the ideal number of people, what benefits will we see and where are the potential flashpoints? Can we rely on political leadership to steer us in the right direction?
