The Police Commissioner and his top executives have undertaken a crash course on Islam for the first time.

The Federation of Islamic Associations invited them to the Kilbirnie mosque in Wellington this week.

Police say the federation asked them to consider taking an orientation on Islam and Muslims in New Zealand in the group's submission to the Royal Commission of Inquiry into the Christchurch terror attacks.

Maria Rawiri, who directs police commissioner Andrew Coster's office, said it was an opportunity to improve cultural understanding, empathy and confidence through learning and experience.
