Thirty-four people survived, with 31 still receiving treatment in hospital.
Two British women were among those receiving treatment, said the UK High Commissioner to New Zealand, Laura Clarke.
Also among those listed as missing or injured were Australian, US, Chinese, Malaysian and New Zealand citizens.
Prime Minister Jacinda Ardern said she shared the "unfathomable grief" of those who had lost loved ones.
In a press conference on Tuesday morning, she said further rescue efforts were now "very sadly a recovery operation".
