Brad Olsen: Infometrics Principal Economist on the lack of information on the skills being lost due to migration - The Mike Hosking Breakfast

There's an unclear picture of what New Zealand's losing from people moving overseas. 

About 70 thousand Kiwis left the country last year. Of those, 38% were people aged 18 to 30.  

New Zealand had a net migration gain of 27,000 migrants in 2024, just a fraction of the 128,000 gained in 2023. 

Infometrics Principal Economist Brad Olsen told Mike Hosking while there's clear data on the people arriving, it's not the same story for departures.  

He says there's no strong evidence of what skills are leaving, only anecdotes.
