The 27-year-old man appeared Thursday in Auckland's High Court. His lawyer argued his name should continue to be kept secret so he can get a fair trial, according to Radio New Zealand. A judge said he would announce a decision later.
The case has highlighted the difficulty of courts maintaining secrecy in an age when information is quickly disseminated around the world. Last year, some British media decided to name the man in defiance of New Zealand court orders. Search giant Google then emailed the name to some users who were signed up for alerts on what was trending in New Zealand, resulting in a rebuke from Justice Minister Andrew Little.
Google later said it would review its processes. The death of the 22-year-old backpacker last December struck a deep chord in New Zealand. Prime Minister Jacinda Ardern made an emotional apology to Millane's family and more than 1,000 people attended candlelight vigils.
Millane had been traveling in New Zealand for less than two weeks as part of a planned yearlong trip abroad that began in Peru. She was staying at a backpacker hostel in Auckland when she went missing Dec. 1.
Detective Inspector Scott Beard said she met a man for a couple of hours in the evening before surveillance cameras showed them entering the CityLife hotel together. Police have declined to comment on reports she met the man on the dating app Tinder.
Police found Millane's body in a forested area a week later. The man's trial is scheduled for November.
