Jacinda Ardern is meeting with survivors of the mosque shootings and their supporters at a Christchurch marae this morning

The Prime Minister was greeted by Maori elders and Muslim leaders at the Nga Hau E Wha National Marae.

The private meeting coincides with the release - probably on Tuesday - of the Royal Commission's inquiry on last year's atrocity.

Islamic groups are already calling for the Government to appoint a dedicated minister to oversee its recommendations.

They say a single point of Government contact will streamline the response.

Mosque survivors have expressed concern about how the terrorist was able to get a gun licence, and want hate speech addressed.

Ardern is expected to talk after the marae meeting, but appears reluctant to speak about details of the report before it's released.
