Christchurch terror attack: 'We are here' - Ardern speaks to Muslim community

Prime Minister Jacinda Ardern is pledging the New Zealand government's enduring support for victims of the Canterbury terror attack.

Ardern spoke to members of the Muslim community at the Canterbury Refugee Resettlement Centre in Linwood on Saturday afternoon.

She once again expressed her condolences to the community for the incident and said the country is grieving together.

"You'll see here with me today is the Deputy Prime Minister, also the leader of New Zealand First; the co-leader of the New Zealand Green Party, James Shaw; the leader of the Opposition, the Honourable Simon Bridges.

"Members of Parliament from across the political divide, because New Zealand is united in its grief and we are united in our grief."

She pledged the government would continue to provide support to those affected, not just in the immediate aftermath but for the coming days, weeks and months.

"We are here now, but we will be here whenever you need in the coming days, the coming weeks, the coming months.

"Our show of solidarity is just not in the here and now. New Zealand is a place that we cherish equally for its inclusiveness, for its diversity and I will consider it my personal mission as Prime Minister to defend that so long as I have the privilege of holding this office."

Forty-nine people were killed in the attack, which targeted two mosques on Deans Ave and Linwood Ave in Christchurch.

Canterbury DHB says 48 people are being treated for injuries, including two who are in critical condition. One of the critically-injured people is a five-year-old girl, who has been flown to Starship.
