Police had earlier confirmed Irene’s killer was a man known to her, and confirmed the Herald’s reporting when contacted.
The Herald understands Katsougiannis owned the property where she was found. She had worked as a piano tutor at Queen Margaret College, and also coached netball in the community.
She had lost her husband six years previously.
The principal of Queen Margarets, Jayne-Ann Young, told the Herald she was deeply saddened at the loss of Irene.
“Queen Margaret College is saddened to learn of the passing of our very dear colleague and friend Irene Katsougiannis,” she said.
“Our thoughts are with her family. As always, we remain focused on the wellbeing of our staff, students and whānau throughout this difficult time.”
