National population growth is predicted to slow to less than 1 percent each year for the next decade.

But what growth remains will be highest in Northland, Auckland, Waikato, and Bay of Plenty.

And it will also continue to climb in the 65-plus age range, growing by 3.2 percent each year between 2021 and 2031.

Infometrics' chief forecaster Gareth Kiernan spoke to Charlotte Cook about the projections.
