He did not speak but appeared to be listening intently to proceedings.
His lawyer James Rapley QC entered a not guilty plea on behalf of the accused.
A tentative trial date has been set for June 2023.
The Crown did not oppose the ongoing suppression.
The man was remanded in custody until his next appearance in April.
After her death, Herrera's family paid tribute to her online.
One relative said a lot of people admired Herrera for her "value" and because she decided to make her life in New Zealand.
She moved here about 10 years ago to study and fell in love with the country.
"Although you were far from your loved ones you always had a positive and strong attitude facing challenges," her relative wrote.
"You were not only a great professional but a tireless warrior.
"You taught us that there are no impossible goals. You lived to the fullest enjoying this world with a lot of attitude full of affection towards others and always being a great daughter, sister and friend.
"I join the pain of your mother, your brothers and other relatives. We will always remember you."
