The Prime Minister has announced a new initiative to research social media algorithms, but does not yet appear to have buy-in from some key tech players.

Jacinda Ardern made the announcement in New York this morning, after co-hosting a summit with the French president Emmanuel Macron.

The initiative is backed by New Zealand, the United States, Twitter and Microsoft, but is notably missing the giants Facebook and Google.

Internet NZ's interim chief executive Andrew Cushen spoke to Māni Dunlop.
