A new study shows artificial intelligence could displace up to a million jobs.

The New Zealand-based artificial intelligence report considered 58-worldwide AI studies - applying them to a New Zealand landscape.

But Tech Industry Association CEO Graeme Muller told Mike Hosking any job changes would be over a 20 to 40 year time period - and normally more than 10 million jobs would be lost and changed in that time anyway.

"It's not something that we should be afraid of, there will be jobs going, there will be changes to jobs but that's happening all the time.
