Editor's note

Nau mai, haere mai - and welcome to this week’s New Zealand newsletter.

First-generation New Zealanders - people who were born elsewhere but have settled in New Zealand - make up a quarter of the population. This makes New Zealand super diverse, and Auckland in particular is “more diverse than London”. But as AUT cultural studies researcher Arezou Zalipour writes, this diversity is not reflected on our screens.

Globally, more people live in a country other than their place of birth today than ever before. The number of migrants is expected to grow, but Akhteruz Zaman and Jahnnabi Das explain that a clear definition of who is, or isn’t, a migrant remains a challenge.

Last week’s Christchurch Call summit has achieved tangible outcomes, with tech companies and world leaders signing an agreement to eliminate terrorist and violent extremist content online. But Massey University lecturer Kevin Veale says it was only a first step and needs to be followed up with systemic change.

For those of you who are now experiencing Game of Thrones withdrawal, I have resurfaced an earlier article, in which Victoria University of Wellington psychology lecturers Christel Devue and Gina Grimshaw describe how the popular show lives on as a face recognition research tool.

You’ll find more about GoT in the collection of articles from The Conversation’s international editions, which also includes the latest on the Australian elections.

If you’d like to read more interesting articles by New Zealand authors, you’ll find them all on this page. Feel free to forward this email to anybody you think would enjoy this newsletter. They can sign up here. Thank you for reading. Ngā mihi nui ki a koutou.

Migration is a growing issue, but it remains a challenge to define who actually is a migrant

Akhteruz Zaman, Massey University; Jahnnabi Das, University of Technology Sydney

Officially, the number of migrants globally reached 258 million in 2017, increasing by 49% since 2000. But the lack of a clear definition of who is or isn't a migrant complicates the issue.

The ‘Christchurch Call’ is just a start. Now we need to push for systemic change

Kevin Veale, Massey University

While the "Christchurch Call" summit has made concrete progress, we need to keep up the pressure on social media companies to become more transparent and accountable.

It’s vital we clamp down on online terrorism. But is Ardern’s ‘Christchurch Call’ the answer?

Dan Jerker B. Svantesson, Bond University

Being seen to lead is clearly an important political aspect of managing online content. But internet regulation must focus on creating policy that is clear, accountable, balanced and open to appeals.

Why do we mix up faces? Game of Thrones might help us find the answer

Christel Devue, Victoria University of Wellington; Gina Grimshaw, Victoria University of Wellington

Facial recognition is a crucial skill, but difficult to test accurately. Researchers are taking advantage of the popularity of Game of Thrones to test the limits of our ability to identify a familiar face.
