British backpacker Grace Millane and the man accused of her murder were spotted kissing on CCTV while on a Tinder date, a court heard.
Footage shows them in bars and at the hotel where Miss Millane is alleged to have been killed in New Zealand.
Miss Millane, from Wickford, Essex, was on a round-the-world trip when she died in Auckland, last December.
During the date Miss Millane messaged a friend about the defendant, saying “I click with him”, the jury heard.
Referring to the footage “just short of six terabytes of data, which is a significant amount” was examined, detective Adam Bicknell told Auckland High Court.
It shows Miss Millane leaving the Base Backpackers hostel and walking to the Sky City entertainment complex, where she met and embraced the 27-year-old defendant, who cannot be be named for legal reasons.
The suspect denies murder.
Miss Millane, was last seen in Auckland on 1 December, before her body was found a week later.
Referring to the messages she sent during the date, a letter by her university friend Ameena Ashcroft was read to the jury.
In it, she said Miss Millane told her she was “getting smashed” and the date was going “really good”.
In the hours before she disappeared Miss Millane and the defendant were seen at a burger bar and a Mexican cafe, before going to the Bluestone Room – all venues that are part of the Sky City development.
Footage shows they spent just over an hour at the venue, during which time the defendant leaned across and kissed Miss Millane lightly, before then putting his hand on the back of her head and kissing her in a more sustained manner.
They continued kissing and talking for a while, before leaving and walking arm-in-arm down the street and into the lobby of CityLife at 21:40.
They entered the lifts and Miss Millane followed the accused out of the lift to his apartment on the third floor of the hotel.
Prosecutors allege she was strangled to death in the apartment.
The defence team argues Miss Millane died by accident during consensual sex, saying “acts designed to enhance sexual pleasure went wrong”.
The court has been told he buried her later in a suitcase in the Waitakere Ranges, near Auckland.
Miss Millane’s death prompted an outpouring of public grief in New Zealand with the country’s Prime Minister Jacinda Ardern apologising to her family.
The young woman had been on a round-the-world trip, travelling alone in New Zealand for two weeks, following six weeks in South America.
The trial is expected to last one month.
