The Ministry of Foreign Affairs and Trade (MFAT) is still trying to contact 50 New Zealanders who may have been in Samoa during Wednesday morning's massive earthquake and subsequent tsunami.
Five New Zealanders have been confirmed dead and there are grave fears for three others.
MFAT said they had received inquiries about the 50 New Zealanders, some of whom may no longer be in Samoa.
It urged anyone who had heard from loved ones to call 0800 432 111.
New Zealanders still in Samoa should contact friends and family in New Zealand to allay concerns.

"Grave concerns" were held for Matamata sisters Petria and Rebecca Martin, who were staying at Taufua Lodge resort in Lalomanu, the worst-hit area.
The sisters' bodies are believed to be lying in a Samoan morgue, but they have not been formally identified.
Their parents, who arrived in Apia yesterday, did not wish to see them because it was not the way they wanted to remember their daughters, the Herald on Sunday reported.
They instead planned to visit today the beach where the sisters were swept to their deaths.

Officials hoped to formally identify them today using dental records.
