She had believed she had been talking to a "decent guy".
"At the time it was just legitimately all normal. The only weird thing I thought about him was that he asked me for feet photos and of me with my high heels on."
On the day she claims she was due to have met the accused man, police allege he met Millane at SkyCity in central Auckland.
Millane's body would be found a week later 10 metres from a roadside in the Waitakere Ranges after 18 police officers, including forensic experts, scoured the bush.
Accused's former flatmate
The claim about the proposed meeting comes as a former flatmate spoke to Radio NZ about feeling uncomfortable living with the man now charged with Millane's murder.
She said her living companions had interviewed him over a video call before he took up the last room in their four-bedroom flat.
The man was a regular user of dating apps and the flatmates began wondering if he was employed, she told RNZ.
After two weeks the group "finally built up the courage" and asked him to leave.
He said his mother had died and he needed to return to Sydney, she said.
"So he left that night, on the pretence that he was going to Sydney, and then when we came home from work the next day he'd cleared out all of his stuff," she said.
"The way that it happened, the way he left so abruptly, we actually got the locks changed the next day," she said.
