Police are working through hours of CCTV footage, as they investigate the disappearance of a British tourist

They've revealed 22-year-old Grace Millane was last seen at the City Life Hotel with a man last Saturday night.

Police have spoken to that man and have been working in an apartment at the hotel.

Detective Inspector Scott Beard says his team still has a lot of work to do this weekend.

He says the images have to be checked in real time, as if you go too too fast, you'll miss something.

Grace's father has travelled to New Zealand and appealed for public help in the investigation.
