The brother of an English tourist who has been missing in New Zealand for five days has spoken of the family's concern for her.
Grace Millane, 22, from Essex, came to New Zealand about two weeks ago and had been staying at a hostel in central Auckland.
She had been keeping touch with her family back home through instant messenger, but has not been heard since December 1.
Her family, who said they spoke to her "most days", became concerned when she failed to reply to birthday messages on Sunday. They said her silence was "completely out of character," BBC reports.
Graces' brother, Michael, told the BBC his sister graduated from the University of Lincoln in September and had planned to go travelling around the world.
Before coming to New Zealand she travelled as part of an organised group through South America for six weeks..
However she was travelling alone when she came to New Zealand about two weeks ago.
"It was what she wanted - she wanted to see the world," Michael said.
Her family reported her missing to New Zealand Police who are in the process of investigating her disappearance.
Michael said his sister last spoke to family on Thursday and has not posted anything on social media since.
Michael said she had not travelled alone before and it was "completely out of character for her not to have been in contact with us and her friends".
"We are really, really worried and concerned about Grace. We just want her to get in contact," he said.
The family have posted on Facebook in the hope that others travelling in New Zealand can help find her. Thousands of people have shared the post.
Grace's father will fly to New Zealand, Michael said.
