The family of a British woman who went missing in New Zealand nearly a week ago are appealing for information on her whereabouts.

Grace Millane, who turned 22 on Sunday, arrived in Auckland two weeks ago.

Her brother, Michael Millane, told Sky News the last person to speak to his sister was their mother last Thursday, and that not hearing anything from her was unusual.

“One of us would usually have a chat or a text every day,” he said.

“It was her birthday on Sunday but we hadn’t heard from her.”

Mr Millane told Sky News their father was due to fly out on Wednesday evening and that they are receiving assistance from UK and New Zealand authorities.

“The Foreign Office are helping, phoning every two hours with an update and requesting further information. It’s difficult with the time difference but the police out there are working round the clock. I just spoke to their night staff and they are reviewing their social media and looking at CCTV.”

Ms Millane, from Essex, is taking a year out travelling and arrived in Auckland two weeks ago after spending a month in South America.

She had been in South America with friends previously but set off on her own to New Zealand where she was staying at Base Backpackers in Auckland.

Ms Millane graduated from the University of Lincoln in September after studying advertising and marketing.

A Foreign Office spokesman said: “We are in contact with New Zealand police and providing consular support after a British woman was reported missing in Auckland.”
