Marija Belancic described the moment her daughter finally contacted her from Kaikoura after nearly 12 hours of waiting as a "blessing".
Ms Belancic's daughter, Jovana Nedeljkov, was travelling the South Island and staying in Kaikoura when the powerful earthquake struck.
Ms Nedeljkov, of Auckland, contacted her mother at 1:34am via text to say she was moving to higher ground, but her mother did not hear from her again until around 1:30pm with the news she was safe.
She said her daughter was one of many tourists feeling "stranded".
Other people are raising concerns for missing tourists via social media with one user tweeting "Looking for news on my brother Luke Bennett and girlfriend traveling in Kaikoura".
"Visitors can contact their local i-Site information for support with travel arrangements," said Tourism New Zealand spokesperson Deborah Grey.
"International visitors seeking additional assistance should contact their Embassy," Ms Grey said.
Tourism New Zealand recommend tourists should keep an eye on news sites for the most up to date information.
A Civil Defence spokesperson said, "If you need to get hold of someone, use your usual means (i.e. text message, social media, the emergency plan you may have had in place). If you still can’t get hold of them and are concerned, call the Police."
