The National Remembrance Event for the March 15 terror attack has been cancelled due to coronavirus.
A large crowd, including many who travelled to New Zealand from overseas, was expected at Sunday's national event in Christchurch to mark one year on from the attacks on two mosques that took 51 lives.
Prime Minister Jacinda Ardern said while there was still no community transmission of Covid-19 in New Zealand, a precautionary approach was being taken to protect the health of all New Zealanders.
She said it was a "pragmatic decision".
"We're very saddened to cancel, but in remembering such a terrible tragedy, we shouldn't create the risk of further harm being done.
"The advice we received for this event, is that based on people travelling from different parts of the country and from overseas, if there was a case it could be difficult to trace those who had come into contact with that person, so we are taking a cautious approach."

Ardern said March 15 had now become "an opportunity for every New Zealander to reflect in their own way on the events of a year ago", and to recommit to the values of inclusion and love demonstrated so clearly after the attacks.
Tony Green, media spokesman for Masjid An-Nur (also known as the Al Noor Mosque) said they accepted that the event was cancelled over health concerns.
"Our consistent position is with regards to security we take police advice, and it would be unwise not to take health advice on this."
Green said it was said in Islam that every action is to be judged by its intention, and the intention of the cancellation was to look after the health of the community.
The event was planned for Horncastle Arena, and would have featured speeches from the imams of the Linwood and An-Nur (or Al Noor) mosques, a short film, several musical performances, and an address from Ardern.
The cancellation was announced at about 1pm on Saturday. A sixth case of coronavirus in New Zealand was confirmed in Auckland at that time. There were currently no confirmed cases in Christchurch.
