Harrap, 27, failed to return home from one of her frequent early morning walks up Mt Albert, prompting a search.
Her body was found later that day by a member of the public and police launched a homicide investigation.
A man has been charged with her murder and sexual violation and is next due to appear in court on October 13.
Harrap's death rocked the community and left women in the area feeling unsafe to walk alone.
"It's going to take an awfully long time to build that sense of security and trust back up because even though [a man] has been caught ... what's to stop it from happening again?" one local told the Herald.
Many are hoping they can grieve together once Covid-19 restrictions in Auckland ease.
Meanwhile, Harrap is being mourned by her wide network of family and friends.
She is being remembered for her involvement in disability and vision impairment charities such as Star Jam and Heart Kids.
A number of people spoke to the Herald about how Harrap's smile and infectious positivity will be sorely missed.
