Prince William has arrived at the scene of the first Christchurch mosque shooting as he visits the city's survivors.

Joined by New Zealand Prime Minister Jacinda Ardern, the Duke of Cambridge on Thursday morning was greeted by Imam Gamel Fouda at the Masjid Al Noor, where 42 of the March 15 attack's victims were killed.

The Prince expected to give a speech for city's Muslim community, whose members were steadily streaming in during the morning.

The second day of the Prince's sombre and low-key visit to New Zealand began with an appearance at Christchurch Hospital, where a five of those injured in the attack are still in care.
