A shocked friend of Ms Pert told the Herald today she was a "kind and gentle person".
Dr Rona Wang became Ms Pert's friend when she was teaching her at the New Zealand School of Acupuncture and Traditional Chinese Medicine. Ms Pert had been studying for her Health Science masters degree in Traditional Chinese Medicine.
Dr Wang said it was "very sad news".
"She was so very kind and beautiful. A very intelligent woman with much knowledge," Dr Wang said.
"She was a great mum to her daughter and son, I am thinking of her family."
Dr Wang, a gynaecologist and pediatrician, said Ms Pert became interested in Chinese medicine when she was pregnant and had some growth issues.
Ms Pert went on to edit papers Dr Wang had written on Chinese treatments for issues such as miscarriages and mouth ulcers.
"I wrote articles about Chinese medicine and she would edit them for me in English," Wang said.
Dr Wang had a healing centre in Birkenhead but moved to Sydney three years ago. Her New Zealand-based accountant called her in Sydney to deliver the news about Ms Pert's death.
The building manager at the Auckland city apartment building where Ms Pert lived said he had known her for a while and she was a lovely woman.
"She was fantastic. She just was," he told the Herald.
He would not confirm whether Ms Pert's two children lived in the apartment with her.
Family of Ms Pert travelled to Auckland today and met police investigating her death.
At the Whanganui home of Ms Pert's parents this afternoon, a visibly upset man said they did not have any comment.
Mr Hooper said the Operation Solitaire homicide investigation team had a lot of work to do piecing together the events before and after Ms Pert's death.
"Our sympathies are obviously with Joanne's family and friends and we are committed to making every effort to ensure a robust prosecution is achieved. Staff were back at the Shore Rd scene earlier today and others are carrying out background inquiries into the accused."
Several other inquiries will take weeks to complete, he said.
"We are relieved that we are able to reassure members of the community that the alleged offender acted alone and is remanded in custody."
The occupants of the property where Ms Pert was found have returned to their home. They would not comment when approached today.
Ms Pert's name was suppressed this morning when the man charged with her murder appeared in the Auckland District Court. The suppression lapsed at 4pm.
The 24-year-old Mount Roskill accused was remanded in custody until his next appearance in the High Court in Auckland on January 27. His name suppression will be revisited then.
He appeared wearing a blue boiler suit.
Judge Claire Ryan ordered a number of reports including a psychiatric evaluation. The accused did not apply for bail.
He appeared calm during the short hearing. He smiled once towards the end of the appearance.
Ms Pert was either walking or jogging along Shore Rd when she was allegedly attacked and killed by the Auckland man yesterday.
The stranger allegedly used a weapon to fatally attack her, and she tried to get help at a nearby house.
