Twitter's boss is in New Zealand on the latest stop in his global tour.

He'll meet Jacinda Ardern in Wellington today. The pair first met in Paris prior to the launch of the 'Christchurch Call', where the social media platform was among the first to sign the voluntary set of guidelines.

Gorilla Tech CEO Paul Spain told Mike Hosking the social media boss has been regularly admitting to audiences that Twitter faces a range of challenges.

"There seems to be a lot of work going on behind the scenes at Twitter to try and address some of those things that have been a challenge." 

He says building relationships is a key part of creating change.

"This is an indicator that Twitter are they're keen to talk, they're keen to be seen as doing the right things and making the right manoeuvres and changes."
